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.

i was a GM mechanic for many years, the problem you are having is one of your mode door actuators has gone bad, most of the time it is the actuator on the drivers side that causes the problems, i have seen this many times, sometimes you can take it to the dealer and they can hook the computer up to it and recalibrate it but most times it has to be replaced , it is located under the dash in the area above your gas pedal.

The problem is most likely a bad dual climate control valve. This component is located on the right side near the radiator under the hood. It will have several coolant hoses hooked to it and 2 silver cylinders protruding from it. You can clamp off the heater hoses at the heater core and see if both sides cool then and this will tell you that the valve is letting coolant thru when it shouldn't be.

This will narrow it down to either the valve or the control head inside the car,or wiring in between them. The only way to narrow it down further is if you have a scan tool that could access the climate control data. Have seen several of these valves cause this concern and have only seen one control head cause it.

SOURCE: Air/C, blows hot air on drivers and cold air on passenger side?

The vent actuator my need to be reset, this can be done by removing the HVAC fuse from the fuse panel for 5 min or disconnecting the battery. If the vent actuator does not correct it self, then it's most like going to have to be replace due to internal parts have broke in the actuator.
Thank you for using fixya and it's common for the vent actuators to go bad after a few years, the internal parts are made of plastic and get brittle after time.

SOURCE: 2004 Chevy Silverado AC is blowing warm air on passenger side.

You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

SOURCE: a/c blows hot air on drivers sde

The actuator door on the driver's side is out of position and needs to be reset. Remove the negative battery cable for 1/2 hour to reset the computer. Start the HVAC system and you should be able to hear the door adjusting itself and cold should come out of the driver's side vent.

Driver side vent is blowing out hot air,passenger side is blows out cool air


Damper/flap for driver's side is probably stuck. Try moving the selector from cold to hot several times. Also, move the recirc/outside air control if the previous doesn't work.
