Improper HVAC Temperature and/or Air Delivery Due to Failed Mode Door Actuator on Chevrolet Suburban 1500

One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

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
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
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.
is stuck on heat or cold seems to change when it wants to but not by the control assembly.
The door controlling the air to the defrosters and the floor will not work. Heat comes out but will not go to the defrosters.
front a/c blows hot rear a/c blows cold
actuator reprogrammed and relaced left temp. valve.
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.
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 reported this same problem months ago. Since then, mechanic tested 4 actuators and one was reporting an outside temp of over 150 degrees, but it wasn't the driver's side actuator. I don't recall which actuator it was. Replaced it, and have had no problems for the last two months.
My ac blows hot on driver side and ice cold on passenger side how do I fix it
on the driver side is blow hot air off and on
have to stop , put in park turn off engine and restart. Then it works for veriable time frame then do it again.. dealer wants 100.00 to look at it, no guarantee of fix. WHAT NOW?
Front vents blow cold/hot correctly, but all rear vemts blow warm-hot. Dials are missing on the temp controls, but i used a pliers to see if it was the dial setting & nothing changed. I j7st keep the vents as closed as possible for now, but its hard to cool the whole suburban from just the front.
