THE FIX!!! As mentioned in the video the "Driver door module" was bad. This is the window switch panel. I replaced the switch panel and issue has been resolved. Video removing panel here: kzfaq.info/get/bejne/edSBp9STvMmaqGQ.html

As a veteran Mechanic of 19 years, this is by far the best test proceedure I have ever come across on youtube. Well done!

My man! 3 years in and this video is still complete gold! Not only did you walk me through the entire process successfully, but you also diagnosed my exact problem all the way down to the wife!

Dude, this is one the best videos tackling this subject I’ve ever watched. Not only are you thorough, but you are clear. I’d love to see you do more electrical troubleshooting stuff personally. I love it. And I love wiring. It is one of my favorite parts of working on cars. I know that probably sounds crazy to most of these folks, but I recall you saying that with your bg, you had an affinity for it as well. So please, sensei, teach away!

Old video, but a 45 year tech here. You did it correct, but there is a faster way. Your DVOM will let you test for voltage drop at each fuse, any fuse that has a voltage drop is drawing current.

I know we all want to save money,but based on this it makes you understand why they charge so much trying to find issues like this. Brilliant video 👍

You’ll never know truly how much this video makes my heart scream with hope

Don't hang out or listen to people that tell you it's better to disconnect the positive battery terminal. They have NOOOOO idea what they're talking about. YOU are correct in why you disconnect the negative cable FIRST.....and for the exact reason you stated. Thank you for thoroughly explaining exactly why patience is VERY important when troubleshooting electrical probs.

Got me headed in the right direction. I’ve had a conversation with the other drivers in the house, that if anything looks weird or not right, let me know to help avoid two days of troubleshooting. Great video...you’re an excellent instructor and teacher.

It’s a great example how to stay calm, think problems through step by step, to find a resolution. I think too many people panic, either thinking they don’t know/can’t fix issues or stressing how much it cost to have others do the work. Many times, if people will have enough faith in themselves to try they can be successful! 👍👍👍

My friend I’ve been a master tech for 45 years and I thought I was best but you blow me away that was great

Great basic info video. Plain. Simple and understandable. Useful for more people and not over complicated. Too many people make videos for "look how smart I am" instead of "let me help you."

Huge thanks to your wife! Without her not mentioning the door lock upfront, we would not have got such a useful vid. ;-)

FINALLY SOMEONE WHO EXPLAINS IN DETAIL!!! Thank you for the help you rock!! 😎😎😎

I appreciate your straight forward and thorough approach to the troubleshooting you did. Thank you for sharing those little details that make it simpler and can keep you sane if your having trouble with things. Good job and thanks. Ill approach things that way next time and with patience! Lol

I really appreciate you taking the time to thoroughly explain the function of the multi meter and explain how the computer takes time to shut down. Very helpful and appreciated. Thanx!!!

Great comprehensive video! Well done and thanks so much for the effort put into this. Patience is key with this issue.

Hands down the best video online on how to track down a parasitic draw. Anyone with the slightest mechanical/electrical inclination should be able to follow along step by step. Thank you for taking the time...

I came across your video among many others on battery draining...and I must admit that I tried others video on trying to find out what was causing my battery drain but had no luck at all...going through more videos I came across yours and figured what the heck and low and behold you showed me something different...to turn the ignition on to rest everything and I seen a difference in my readings but the kicker was the detail about the door lock...I bought my truck used and the back hatch never locked which wasn't a big deal but turns out to be my battery drain I've been having since I purchased the truck...thanks for the informative video!!!

One of the Best video, a higher level from the basic techniques of diagnosis for parasitic drain!! Surely a beneficial knowledge for DIYers!!

Bubba, You're golden. 5 minutes into your vid and you demonstrated, described, and detailed your video title immediately and clearly. Thank You For Your Time, Effort, & Generosity!!!

Saw on another video, the chap tricked the vehicle by keeping the door switch closed. Then you don't have to wait for the cycle time. Cheers

I typically work on old non computer cars and this just opened up a world of knowledge on how to track an electrical problem. Thank you very much. Never would have thought to power up then down like I was driving in order to charge the system then wait until it sleeps again to track down an issue. I will for sure use it on my 2001 VW which has a drain but one that takes about a week or two to drain the battery. I have the time to wait. I had always assumed it would just go to the proper level right away.

This is one of the clearest, easiest to understand videos on troubleshooting electrical issues on KZfaq. Outstanding job!

Wow! Thanks for the great pointer. Good analysis and investigation skills. You help us be better and get better at looking after our cars. Thanks a lot!!

Correct, ALWAYS disconnect the negative first. Most EXCELLENT video, perfect diagnostic approach. Many thanks. I happen to have the same vehicle, but not with any problem. My GMC, however does have a parasitic draw that I will track down with my new-found confidence from your instructions. Good stuff, thank you.

Great vid, well explained. I happen to have a 2000 Super Duty with a loss.....and drivers door power lock doesnt work properly. I would have never guessed the door lock could cause a long term loss but now I know how to check....THANX!!!

Thank you for this video! Going to be looking at mine because it seems to always be weak after a new battery been put in. Love the patience you've put in to this to help anyone that is fighting this.

Very handy, and the most well explained on this difficult subject. Be patient, so says the master.

I was so glad to find someone using the exact same multimeter, so I could follow along without assumptions or guesswork. Thank you forcall that you do...

Thanks!!! I've been worrying with an electrical issue on my ride for over a week now.. just got it fixed after watching your video!

Holy Cow! After watching your video, I went outside and locked my passenger door manually from the inside and after closing, testing from the outside to ensure it was locked. Then, I got inside, turned the ignition twice and IT STARTED!!! It hasn't started for a while. I too have had a locking issue with my passenger side thinking it was the locking mechanism. Turns out it was! The irony. Thanks Iron Man!

As a retired, certified electrician who also tinkers with low voltage systems it's refreshing to see someone use common sense to troubleshoot a problem. I don't have a parasitic drain but the title caught my attention. And I did learn something about vehicle systems, they need time to shut down. Thanks, good video.

Excellent tutorial, thank you. I have had parasitic battery draws on numerous occasions and they drive you crazy. I have one currently on my son's vehicle so I will try this method. Thank you again.

You helped me brother. My Silverado 1500HD started draining the battery. I was two days into this process and when I saw you find your driver door module fault. I jumped ahead to that step. GM like you , door switch like you, BINGO! I GOT LUCKY. Thanks a bunch. I subbed👍

One of the best videos I’ve watched on finding parasitic draw on a vehicle. Thank you!

Thanks. I learned so much, especially about patience. I had been using a clamp meter, which was just too erratic. I can also see that a lot of work was put into making the instructional video itself. Really appreciate it. I might be able to find the problem now. Just takes a rudimentary knowledge of amps on my part.

This was an amazing walk through, much appreciated. I’ve been the guy before chasing draws that we’re “normal” thinking they were the issue 🤦🏾

Thank you! Great video. It addressed a couple of reasons why I had not been able to identify the source of my battery drain. Excellent!

A very well presented and explained video showing methodical troubleshooting techniques...proper use of terminology too...a big compliment! and cheers from Connecticut!

Thank you so much I have been chasing my shorts instead of actually having a process that I should have considered God Bless & be safe

Like everyone else has said the best parasitic draw video I have seen. I have been looking at the ranger videos from the start and they are all good. But I can tell from this video that this is your speciality. I have a 2000 Silverado and this could help me someday. Thanks Eric

You may have just saved me thousands of dollars because I live in a different country with demonstrably shitty mechanics, especially when it comes to electrical issues. Thanks so much for sharing. Subscribed so I can learn more.

That is weird.. Great analysis. Useful techniques, including patience and thoroughness. Thanks Guy.

I've watched probably a dozen parasitic draw vids on KZfaq and this is the best. I'm still trying to find the issue on a 2001 Lexus RX300 but I think your tip "WAIT" is probably exactly the thing I'm missing. Kudos and thanks for the video.

Hit every button the driver can reach (door buttons, dome light door sw, etc, ask driver about any issues prior to dead battery, lesson learned. Been there, the "oh by the way" the next day, oh THANKS for letting me know THAT in advance, CHEERS to your technique, good to watch video, keep them coming!

Great detective work. I had a door control module issue with my 2000 Corvette. Instead of spending $500 on a replacement module, I took it to a guy who de-soldered and replaced three or four relays on the module with new (and improved) relays. Fixed the problem.

Common sense approach to a fix by observation and cycling the ignition circuit! You rock dude!!!

I have been a mechanic since I've been born hats off to you dude good job

Well done !! I did learn a lot watching your how-to. Thank you for your time.

I have watched all the video's available and this one gave me the best detail information. My truck is a Ram 2500 and I believe my problem is in the smog device circuit after using a plug-in computer that said there was an error message on that circuit. That is where I will begin to use what I have learned from this video to save time, as I am only so patient. I will refer to this video during my search for the parasitic draw killing my batteries. Thanks for the detailed information for me to use

Impressive job troubleshooting a difficult problem to isolate and resolve. Thanks for sharing your experience and knowledge on this topic. My challenge is with a 2001 Ford F450 with the 7.3L turbo-diesel.

4 year old discovery.. This is one of the best videos on this subject I've seen 👍 .. subscribing

You are a GOD!!!!!! Very nice explanation and demonstration. I now feel encouraged to try this on my 40 year old car. Should be a bit simpler I hope. 🙂

Brilliant video. Thanks so much, you make it so easy to understand what you're doing and why.👍

Very good how-to video!!! I love your patients and resolve. Thanks for posting.

Dude thank you for doing this, explaining it very well and especially the details of cycling to find the pattern, emphasizing patience. That is gonna save alot of time and cursing, so thank you.

Thanks for the video. You saved a lot of people, a lot of suffering. Thumbs up.

Very well done and fun to watch. I have a drain on my boat battery that I suspect is coming from the radio. I've always just unhooked the battery after a day of fishing, but this gave me the drive to do some troubleshooting. Thanks.

I troubleshoot electronics quite often… Just not on vehicles…. Hate working on cars!!!! I like the way you broke it down and the process of elimination!!!! Cut it in half, cut that in half, cut that in half and there is the problem!!! I also work with inverters… It take time for them to discharge…. You wait for it tactic is very good!!!!! Well done!!! I would watch more if your videos if you produced similar content… Again, nice job! Good video!!! Thank you!!!

Outstanding video, very well done. I think I was lucky enough to find this video first, don't think I need to waste any more time looking for other videos. Thank you.

This was brilliant, thanks for the clear instructions and reasoning behind doing what you're doing. Will hopefully help me find the drain on my car!

You’re very good at making your videos I’ve been a mechanic for years but you showed me things that I didn’t know and I appreciate your videos. Good luck to you brother.

Finally a good video that showed me exactly how to put the meter in series, thank you! 👍👍

Excellent! this is the best explanation/example and it shows how the computer cycling has the rest befuddled.

Wonderful video. I know zero but you explained enough I going to try. Thank you people like you make the world so much better and no real greed just helping fellow man or women.

thank you i just started working on the same style vehicle with a parasitic draw. thank you again. very informative.

Thank you for posting this video. I really appreciate the people that take the time and effort to create and post these type of helpful videos. I have solved so many problems using KZfaq video.

Patience pays, very logical approach. Good trouble shooting to a complex fault,…..thanks

Thank you. I have a 1999 Ford F350 7.3L Diesel Crew Cab Long bed. Isolated what I thought was a parasitic leak on fuse #15 (Generic Electronic Module (GEM) at 152.2 mAmp. But saw your video and filmed the multimeter for 1 hour. Sure enough, at 45 minutes the multimeter went from 152.2 mAmps to 9.27-12.67 mAmps. It took 45 minutes before the GEM went to sleep. You saved me an unnecessary replacement GEM purchase. Cheers!

Thanks for the video,perfect timing for me!! Added gauges and e fan to my Ranger and now I have a drain somewhere

Ahhh! So glad I found your video. I have the same issue with my Escalade battery draining ( and same meter lol) I will check to see if it’s my door lock first! I’ll be sure to watch it again! 👍🏼

Thank you sir. you made my day a lot shorter, and saved me a trip to the dealership

This was a great video never imagined you'll have to wait that long to let everything go to sleep. great job bro 👍

Best video I’ve seen on this subject by far, thank you sir.

Thank You! That was tedious but I have located the offending fuse and circuit. It's the Stop lights. I also unplugged both of them in the trunk but with no joy. Time to start tracing wires etc. But I can pull a simple fuse and stop the battery drain while I locate the issue. I'll carry a pair of pliers with me and when I stop I'll pull the fuse. Don't need stop lights when parked 🙂 Thanks again for a comprehensive video!!!!!!!

Excellent video brother. I love how you stress the importance of patience. As with all things like this, slow and steady wins the race. Calm patience is the sign of a pro.

Thank you so much as a female who loves to work on her own cars I love to learn new things this video was the best and I understood everything and you where great explaining it thank you

Very much useful for the newbies among us (I for one) who try to DIY, thank you very much :)

This is the best video explaining and showing how to check and fix a draw I've seen. THANK YOU

Thanks for this pall . I absolutly hate electronics and start to loose my temper and kick dents in my car within 30 minutes or so . . . this vid helps a great deal with that.

This video is better than my yoga clases for teaching me about patience.

Electrical is always a challenge. Thank you for the video I'm sure it will be very helpful for me in the future

Thanks, I'm only just starting to wrap my head around the universe-within-a-universe of auto- and marine-electrical engineering and trouble-shooting, and your methodology/explanation has just changed the way I think about these circuits. Kind of like being dropped on a remote tropical island and deciding which direction to go hacking and slashing in search of resources, but being mindful that just because you didn't encounter anything along the paths you've just cut into the jungle, you can't infer that nothing of interest will ever be on those paths if you happen to be traversing one at a different time of day, or in particular after one of your party both discovers and reveals your presence to the islands only other predator (which your wife didn't think was significant enough to be worth mentioning to you at the time!).

Nice work! You said it but I'll say it too - it's critical to wait to see what the current comes down to. Just did a 2016 Elantra, and it got down to 100ma after a few minutes. Thought it was stuck there, but let it sit to be sure, and after about 40 minutes, it went down to 7ma!

Great video sir. I'm trying to track down a horrible drain on my daughters 2002 suburban that kills the battery in less than a day. Thank you for sharing.

I don't use this tool often and neither do most people, but when I see someone use it so wrong I just gotta go brush-up and make sure I'm good to go. Thanks for this video.

A good explanation on how to find a parasitic current draw, I have had a current draw on my vehicle since I've owned it 12 years now, watched a number of YT Videos in the past but they lacked the little things, fortunately your video contains the minute details those other videos were missing, thank you, my Vehicle is a 1994 model and is devoid of all electrical gadgets so this video should help in finding that 12 year current draw.

Fantastic video on how to, I'm on day two and was just told there was an issue with the rear window wiper. Thanks Honey, what else are wives and kids for! lol Thanks For a Great Video

THANK YOU for making this video. This is one of the best parasitic draw videos on KZfaq!

Thank you for this video. Even though I knew that you are supposed to be latient and wait for the various modules to go to sleep, I didn't realize that the wait times would be so long. Thank goodness I've got an ancient car with nowhere near as many electronics modules to wait for because patience is not one of my virtues.

Great video!!! I’m definitely not a mechanic but I’m having the exact same issues with my 05 Dodge Durango and it’s driving me crazy!!! I’m going to try to use this method to help me find my parasitic draw.

So accurately precise your video is Fabulous. Thank You for your step to step zoom.

You’re so clever mate … very well explained

Great video. My ASE Master Tech uncle with over 60 years experience told me always disconnect the NEG cable, so that's what I do.

As an Electrical Engineer I can say well-thought-out techniques. Thank you!

Best video on parasitic battery Drain EVER!!

Absolutely phenomenal video. I'll be using this soon on my Dad's Econoline van!!

I totally understand now how to check from this video so thank you so much! Watched many but this is 👍🏿👌🏿💯 one of the best!

I like your comment about you wife mentioning the issue after your second day of testing. My wife has done the same thing to me with her car.
