Going over most common car heater problems, and how to fix them. If you're getting no heat coming out the vents, either your heater core is not warming up your your air distribution system is not redirecting the flow of air properly. In this video I am showing how the heating system works to help you narrow down what part of the heating system needs further attention in your car.

I love your videos. I showed my mechanic my over flow tank was rusty and foamy like in your video and he said my radiator was no good and I need to replace it that was during the summer. Now about six months later in the winter I have no heat and over heating problems. I am going to show him your video. Thanks a bunch.

You are the best! Excellent presentation, graphics, showing car insides, deeply appreciated. Wish I could buy you a tall beer! I'm female, know nothing about cars, but when mechanic said $400 heater core diagnosis/repair, I came here. Not paying that! Toyota Yaris 2008, stick shift. Heater blows fine but no heat. I must clean out radiator and overflow tank and do a coolant flush. I have 71K miles on this little car and probably overdue. I have to check everything else you mentioned. Very very grateful for your excellent video! THANK YOU!!!!!!!!!!!!!! 😃😃😃

I'm not a mechanic, so this was super helpful. I didn't know that there were so many parts that made the heat/air work. Very impressive! Thanks for the amazing breakdown. I replaced the blower motor. I probably didn't even need to because it stopped working a few weeks later. I found out that it was the pigtail. One of the prongs on the resister was a little burned, so I carefully cleaned it. I had to change the pigtail that I bought from a local automotive store. The wires were pre-coded by letters. I did them one by one. I had trouble getting the original wires into the connector. I taped it up pretty well with electrical tape. One by one, and then together. Please done run the heat/ac on full blast all of the time for long periods as this seems to cause it to burn out quicker. I saw that mine had been replaced before. I hope this helps. God Bless

@ME-pg3sw 6 ай бұрын

@dedebaby2459 Hello, my problem ended up being the pigtail. The hardest part was getting underneath the glove box to get to the wires. I had trouble fitting the wires into the connectors but it did fix the issues. I did replace the blower motor. Very easy to replace. I did check the resister. Only one section was a little burned but I carefully cleaned the prong. Be careful not to run the heat/Ac on high all of the time as it will cause it to overheat. I did get the part from the local automotive store. Advanced Auto Parts. Autozone sells them fairly inexpensive. The Ford Dealership wanted a few hundred dollars just for the resister. Not including labor so I did it myself

And all i could find were suggestions that my water pump was bad. Or might of been the heater core But neither of the ahove suggested the "at idle no heat but while driving have heat" issue as a direct symptom. Thank you thznk you thank you.

Last week, Car Smart told us that it needed a new fan blower and resistor. A nice mechanic in Walmart auto (when I got an oil change) said to order the parts on Amazon and watch a youtube video and do it ourselves. So I ordered a resistor for $14 and a blower for $37 at Amazon. The one company sent the WRONG blower, too small. So my 23-year-old son was only able to put in the resistor. And it did the job!!! We now have heat! It's incredible! I'm just sharing this because my son has never worked on cars before, but replacing it wasn't that difficult of a job. I wish everyone the best at having heat, so they don't blow their circuits like I did trying a portable window defroster! :P Maybe do like me-- take it to a shop and pay a $50 diagnostic fee, and then just do it yourselves. (I don't know why they said it needed a blower though. I'm hoping it wasn't Car Smart being dishonest---- but that it's just hard to diagnose which one is the problem. (Does anyone know if it's hard to tell which is bad?)

Why is your son doing the job? Why not you? Also why ask others - check it out yourself. You do have two hands, eyes, and a brain, same as any man, right? I'm female. I learn how to do everything myself. I got tired of being dependent on men. Now they ask me.

@alohachristine Жыл бұрын

@@mjremy2605 thanks for the comment! I understand where you're coming from about the need for women to develop skills and not only rely on men, but no worries there! I'm definitely not the traditional female. For example, In college, I was the only girl in the welding class! :)) I'm currently remodeling my basement, starting a woodworking business, singing in 4 choirs, am an artist and writer, mom of 5 kids (4 so at home), etc... I could most certainly do car repair so (my son gets his mechanical ability from me), but there's only so much of me to go around! :P so I like to give my sons' and daughters' a chance to learn skills to. My oldest child studies computers and engineering, has the tools to repair the vehicles, and he lightens my load substantially in these things! I'm sure I could do it, but I really just don't have the time! I'm so glad to hear that you are developing skills that once we're notoriously considered male interests!:) God bless you in your endeavors. Christine

If I could give this video 100,000 likes I would. I have a 2000 Jeep Wrangler #WranglerTJ #noheat. Hands down the BEST video I have found if you don't know WHY you don't have heat. Because sure everyone could guess by watching all the videos who's title suggests they are going to help you diagnose the issue but then quickly or sometimes not so quickly the topic gets dominated by what their specific heating issue's solution was and now you van never get those precious minutes or accumulated hours of your life back. But hey look at the bright side, you know now how to solve the issue if you ever one day possibly potentially end up with it. Thanks "Make It Easy Mechanic" you are a rock star! Better then anything I have found even on Jeep Forums, jus dont tell the Jeep guys I said that
