I already spent over $3000 dollars and my heater is not working. I will try your step by step video. Thank you so much for the video
Thanks for all your videos my guy
My truck lost its heater promptly when I used head gasket sealer. I've attempted to flush the core but it has still failed. It has a mechanical control valve that is hooked up properly. Every other possibility mentioned in this video has been investigated. I should have had my mechanic take a look when he was doing a gasket job for me but I didn't and here we are. Advice would be appreciated.
My truck barely has heat and it's not getting up to temp I'm replaced the thermostat also idles a little fast please help!
Thank you for your very detailed vehicle. I greatly appreciate it. It’s helped me a lot and save me a ton of money wasted from high shop diagnostics
Do you have a video on how to replace the blend door actuator if that's the problem.
very helpfull video . fixed problem in minute
Like 👍
My car about five months ago stopped blowing hot air. I floored it and it came back on and hadn’t stopped working ever again for five months until now. I tried flooring it over and over and it just wasn’t working. I can’t believe he mentioned revving your car might work lmao. Now I know my problem.
good job i myself a honda tech 25 years you explained well
I like your way of explaining things , its very helpful thx
I like how u explain step by step 🙌🏾
121k. i think that coolant came from the factory lol
Thx for the tip . My truck gained 50hp
Set it on fire?
Almost 10 years and 10 million subs keep up the good work 👍🏻
Excellent as always Chris!
When I turn on heater I hear it blowing but it's not coming out vents?
Chris..great video. But im stumped. Heater core works, i replaced the control valve, but just stays open. Seems no vacume but the lines are all intact. No heat at all in the cabin, so i expected this to be an actuator at the blend door. But since the vac line is not working, is this the controller maybe?? I now gave a generic vac leak check engine code active.
I have a 2003 ford crown vic i replace the heater core and theremso i get cold on heat setting idk where to look at
excellent like always Chris Fix
THANK YOU FOR SUCH AN INFORMATIVE VIDEO. IM A 46 year old widow and having this exact issue but on a very tight budget. Currently I am stranded due to a snow storm combined with no heat making it dangerous since I cannot see through the windshield due to ice.
Sadly im stuck until tomorrow afternoon when hopefully some sunshine will allow me to complete my 2 hour journey home but I cannot wait to follow your instructions and get my heat working again.
My poor dog is shivering so bad. That’s the hardest part for me.
We are soooooo cold but you’ve given me some hope so we never have to go through this again.
Thanks again.

Wow. I just subscribed! What great detail in your video. I appreciate you not being cocky like some people’s videos. I know about car motors, but would not consider myself a pro. So thanks for the easy to follow tutorial.
Thanks for your video.
Why the radiator it's dirty like that, my is same, and how we can cleaning.
Good job
Hey Cris, I was driving with no coolant on the highway. Going home from work. There was no heater and the temperature meter was going up and then down. And until a point where my car will shut down. It will lose power. Now there's no power. I tried to jump start but there was a mechanic that passed by and he said it's not the battery it was coolant that spilled all over and it got the radiator wet. That's why there's no power. And I asked him what it needed to be done and he said something and to dry up the alternator. What's your take on this?
This probably saved me a grand. thankyou dude.
This video told me why I can't get heat……nice job!!!!
thanks guy. jimbo dog😂
Would any of these also cause poor mpg ? I’ve went through almost a full tank and should have at least another 200 miles , give or take.
Thanks, great video
Thanks a lot!
I have heat but only blows out from the dash vents can't change it to blow on the floor and windshield?
@1:30 nastiest radiator I’ve ever seen
My thermal switch is bad what can I do for immediate heat?
يعني أنك لا تعرف اسمه
I got my heater core replaced by a mechanic, it was working the day he fixed it and it was fantastic, a week later back to how it was before i got it fixed heat not working when i put it on mix. What could it be???
I'm retired and can't afford the. Membership. But thanks for your service.
I got a car with AC deleted and even the blower fan. I believe heater core good when did the two hose touch test. How can I hook up my heater from here to work for my car? I don’t care for the AC at this point
YES FAIR PLAY TO CRIS HELPS THOUSANDS
A couple revs fixed mine after replacing a thermostat and not blowing hot air thank you sir!!
Thanks! it blows hard on my CTS. But only cold air! Even at turning the knob to 90 degrees. Always blows cold.please advise if you can 🎉
Amazing!!! Great tips!!
Thorough knowledge thank you
Still a great video to this day. I went through the complete video, replaced the blower motor resistor per the symptoms. The blower continued acting screwy throughout the different switch positions, then finally found that the culprit was the actual fan speed switch contacts had welded closed in the high speed position. Replaced the switch, and voila! Fan speeds work again! Thanks a bunch for stepping us through the entire system, definitely makes troubleshooting easy when you know how something is supposed to work. 👍
