Got to be careful with latches that don't work and then work all of a sudden, a common problem can be wiring issues in the area between the door and the body where the wires flex with opening and closing of the door. Have been caught out with this issue before and paid for a new door latch when the fault was actually an open circuit problem. Wiggle test at the flex. :)

Nice diagnosis Tom and changing door lock actuators on Hyundai Sonata's are a pain with the module setup!

So... What did you figure out? And what was done to fix it?

Nice one Tom.. I know someone would have thrown a module at it just because they would have guess and not believe 2 latches would go bad.. Only to find one out.One went bad early,customer didnt care for it.till second one goes...

First! 😃 Good to see you back Tom, seems like every one is ultra busy lately 👍 good video bud

Nice to see that other manufacturers (besides VW) also have problems with door actuators! =)

How do I get the door open to work on it? Seems impossible to remove the panel while the door is shut.

Great video man we missed your videos i hope to comeback soon .. thanks

Very nice info and would be more grateful if you could be specific on locating the lock and locking wires for all doors lock of the input connector of the BCM module? Thanks.

What brand are those wire pinch test leads and part number of you have .. Thanks.

Fantastic video great to see you back.

Thanks Tom, nice to see you doing videos again!

Pity there wasnt a stored code for the locks. Then maybe you could see how long theyve been broken before they brought it to you. Im guessing one went bad a while back so they were using one rear door untill that went bad too..

Very good information... Sir, could you show videos on i20 driver side window wiring diagram???? I'm very curious about the auto roll up window features of this car. Would be pleased to hear from you soon. Thanks.

Awesome work Tom and a nice straight forward diag.. Keep up the awesome work Brother I would like to more from you

Good Job Tom..Always enjoy your videos

Always learning from you, thank you!!

Well done sir. Good to see a new video from you

Thank you Tom. Good job. Appreciate your videos.

Fantastic video 💜💚❤️💙👍❤️💙

heh, tha harnesses to the rear doors almost never break in them, the actuators break for sure, lack of overall latch usage and no lubrication lets them gum up and self destruct ;)

awesome excellent way to approach and thanks for sharing MR Tom. cheeeeeers

Thanks, great video!

Please make a video for Hyundai i20 elite car front right door handle button doesn't work when pressed to lock/unlock

Nice diagnosis bro.

Nice job Tom! 👍

It would not have affected your diagnosis but this car has a door jam switch to tell if the door is open. Also the door latches on hyundai/kia vehicles do not communicate or have the ability to set codes. I've done quite a few on kia sorentos and they're all wired the same

Bro, is it possible to get a Hyundai Accent 2005 car central lock and alarm wiring diagran ?

nice video all the best

Nice job on the video.

I am having the same problem with my car as well I got Hyundai i30 so I do I contact you pls reply

Tom, could you tell me where those relays are located on this vehicle?

hi tom, just a quick question. I understand the reverse polarity system. but i dont understand the purpose of the door lock unlock switch in the first diagram. ( in the box that says rear door lock actuator lh). what does that switch do? how does it relate to the motion of the motor. Because from what i can see the motor motion is dependent on the lock unlock switch in the second diagram that controls the relays. Basically if this makes it any clear, not sure what the purpose of the rear door lock/unlock signal from the ip junction is. Thanks for your help!

Same problem with the 2012 Hyundai Tucson. All doors even the truck cannot lock/unlock all the way.

Mine is doing the same thing but mine is the front driver side and the back passenger side how much is it to fix

How did you get the door open?

Sir my car i20 center locking system works only when locked from driver side. However, when locked or unlocked from passenger side, only this passenger door is lock or unlock respectively. The remaining 3 doors are not locking or unlocking!!!! Please help.

When you say "door latch" do you mean the actuator? (Just asking for clarity).

Hi, I have the same problem (front and back, passenger side). So, I don't need the actuators everyone is trying to sell me? Sometimes they work, and sometimes they don't, but even of they don't lock or unlock, they still click and move, just not enough. When it first started, it would only happen when the air temp rose above 98. I thought something had melted, and maybe it could be cleaned. But of course, the mechanic wants the $300 fix

There you go. Verification is a good way to sleep well at night. :)

What if the door lock module fails and the door is shut and will not open? How would you open the door to even diagnose?

ahh, he returneth :))

Interesting how both failed. Wonder how long it was acting up?

Where do I get those wire piercing probes?

In the one that is stuck in lock

CAN THIS BE CAUSED BY SLAMMING THE DOOR? THANK YOU

Within 8 months, 3 of the 4 went bad in my '13. These cars and every part in them are absolute garbage!

Nice beard

door latches dumb stupid common issue. kia and Hyundai.
