Been a while since I updated this but I wasn't getting any heat. First I tried to replace the blend door actuator. is like $15. I am almost positive it wasn't working. For that you have to disconnect the batter, remove the upper glove box and the air bag. It is on the left almost behind the radio. This is on the model with no electronic climate control wish single zone. Also, notice how my dash is cracked. I hate that. That is the bled door actuator way over there on the left. Now it was definitely working but that didn't fix the problem. The air was not as cold but definitely not hot. I was researching replacing the heater core - not something I want to do - when I saw videos of flushing it. So I gave that a shot. -
I purchased my 2021 Yukon AT4 brand new in June. I haven't had to use the heat until recently (I live in TN). The front heat blows warm air while I'm driving, but when I stop at a long light or put it in park, the air starts to blow cold until I start driving it around again. Also, in the rear of the cabin, it's never blown hot air...ever. Even after running the controls on full blast on HI for an hour -- air is still ice cold. I've tried it with the Auto Stop On and Off and it makes no difference. Anyone else have this issue? -
2015 chevy 1500.. 3400 miles. A couple of times the heat didn't work. It always did "next time".. the other day I had to take a 3 hour drive.. it didn't work the whole way there...stopped for an hour..headed back still with no heat (it was 42* so it was not pleasant) Took to dealer - they said they cant find anything wrong, of course, and of course the he was working fine. Its only done this a couple of times in the past 2 months now. Anyone experienced anything similar? It blows out air, and it will adjust the fan speed properly (or what I'm guessing WOULD be properly if it was blowing out heat) based on the temp of the cab. Even when taken off of auto and just turned temp to hi and fan speed up, with AC button off, it was still blowing cold air. Any ideas? Could it somehow be user error? (doubtful) Also when the AC button is on, even when its on heat, is the AC really still running? seems dumb that lights always on even when you have the temp high and its blowing heat.

Hey all. I bought another ride and it came with some HVAC issues . I’m not very good with wiring related trouble shooting so I need your help. Its a 2002 suburban with the base hvac. No digital display and no dual climate. The issues *hot to cold switch doesn’t work *vent change doesn’t work (blows out of front vents only) [The Fan speed knob works fine And all fuses are good] After reading up on the common actuator problems, I decided to try the relearn/calibration of the actuators. This literally did nothing and the part that has me stumped is that the actuators didn’t move at all during this calibration (you should hear them moving and calibrating) So here is my thought on the problem. It’s either... a) Both/ all actuators are bad and need replaced b) The switch panel/ control unit is bad c) There is something else and I’m lost. Please help guys! Is there something I don’t know??
