SOURCE: Problem with AC, dual climate zones

The temperature blend door on the driver's side might be broken or stuck. Also, if this vehicle does not have the correct amount of refrigerant, it will do what you are describing.

SOURCE: Passenger side a/c blowing hot

There's a rod assembly that opens and closes the vents in the car for the automatic climate control. It's supposed to open all vents to the AC feed when in AC mode. BUT, if it slips loose, the default status is to feed heat through (you can open a window in the summer, but you don't want AC blowing in your face and on your windshield in the winter). In my case, the driver's side was working right, pumping cold air, but the passenger side was actually dumping hot air into the car. Friend who fixed it for me told me he just had to drop the glove box etc. on the passenger side to get to the rod and slipped it back into place. I'm not agile enough, but if you are, you can probably crawl around under there and figure it out - or get a friendly mechanically inclined young friend to do it for you. Probably in the mechanic's manual for the Caddy (I don't have one).

Think this will fix it for you - did for me.

SOURCE: Hot and Cold

The most likely cause of your problem is the blend doors under your dash. If they are not moving like they should it can cause this type of problem. You can look under the dash to see if there are any linkages that are disconnected. Some of these are very hard to change so you might want to take it to a repair shop unless you are very good with cars.

SOURCE: Cold AC but weak Airflow---Also Driver side not as cold as passenger

The air doors are controlled by actuators that on of them or so may need replacing.

The drivers side thermostate control will not change from cold to hot. The passenger side works fine. Is there a fuse or relay that I should check?


Hello, this is not a fuse problem. this is caused by a bad tempature door actuator. there are two electric motors called temp door actuators, these electric motors move the temp doors from cold to hot and back. the electric actuator for the drivers side will need to be replaced. once it has been replaced, then a recalibration will have to be perform with a scan tool

I have a 2004 envoy and my air will not blow through my front vents. The air blows fine through my top, bottom, rear and side vents, why is it not blowing through my front vents?


If you recently had a weak battery or replaced a battery the HVAC unit will perform a recalibration of all doors. This causes the door motors to be moved full cycle and the mode door will stick some times. Usually this is the problem. The actuator motor will need to be removed and replaced...sometimes they can be recalibrated, but not often.
Good luck, i hope this helps.

New battery install, now cold air willnot blow on passsanger side


The HVAC system may need to go thru a recalibration. Set all HVAC controls and switches to OFF or fully CCW postions, then either disconnect battery or pull fuse #36 in the rear fuse panel. Reconnect battery or reinstall fuse #36, turn ignition key to ON position (don't need to start) and wait about 2 -3 minutes. If this does not solve problem, there is a problem with the passenger side blend door or its actuator.
