Actuator door quit working and would only blow hot air on driver side and cool air on passagner side when in ac mode.
no heat from the front, but rear heat works great.
Drivers side a/c switches to heat, while passenger side blows cold. Replaced drivers side door actuator, did not fix problem. Turning the a/c off then shutting off car and restarting will reset all doors and actuators, fixing the problem temporairly.
had ac on and driver side started blowing extremely hot air
Cooling only works on upper setting. The heater will only work when the car RPM are increased and will not heat the back vents at all. There is a continuing clicking sound coming from the dashboard.
The door controlling the air to the defrosters and the floor will not work. Heat comes out but will not go to the defrosters.
Driver side Air cond turns to a high heat ---passenger side is fine --this is not a very good condition to have going across the Bonneville Salt Flats in 95 degree weather. I have had 10 suburbans and this one takes the cake -- I have had more problems with this one than all the others combine---the one that makes me most upset is the speedometer --with a $600.00 price take to repair plus removing the whole consul for a week or so. I wish the engineer that thought this one up had it stuff where the sun don't shine along with there fuel pump in the gas tank.
A/C and heat not putting out right temperatures, actuator making sounds. Replaced acctuator
is stuck on heat or cold seems to change when it wants to but not by the control assembly.
front a/c blows hot rear a/c blows cold
Occasionally hot air would start blowing on driver's side, but nowhere else. Stopping and restarting engine would fix it. This happened about twice to four times a month, until the alternator went out, and now it does it full time. This is the first day and after doing some research tonight I plan to disconnect the battery tomorrow to reset the door blend actuator and see what happens. But I haven't seen anyone else mention an alternator replacement being the trigger for this, and I want to educate myself before a mechanic potentially decides I need a new compressor.
actuator reprogrammed and relaced left temp. valve.
My ac blows hot on driver side and ice cold on passenger side how do I fix it
Heat coming out of drivers side and cool from left side
goes from cold to hot the door flips I replaced the door moter but it still does it
replaced door actuator
I had no heat on drivers side. Replaced actuator and now I have no a/c on drivers side.
First thing in the morning I'll have heat on the drive side then it turns cold. But I will still have heat on the passage side. It's a Chevy Silverado 2500 hd. 2003. 6.0 liter.
AC on driver side blows hot, while passenger side and rear seat AC blow cold
The AC is blowing hot on the drivers side, and cold on the passengers side. I have not gotten it fixed yet.
