SOURCE: 1999 cadillac Deville cold air blowing out passenger side vents

Sounds like a Blend door issue, but could be the controller switch, Test ALL modes of operation to see what works and what does not. That should narrow it down a bit. The Blend doors are flap/ doors that regulate air flow, newer vehicles are plastic - electric assemblies ...prone to failure. Any clicking or thumping noises during switching modes and on-off suggest a bad Blend door. Hope that helps...good luck

SOURCE: 99 STS AC is blowing hot air

I had the same problem but it was blowing hot air on the passenger side of the car. I assume you have the dual zone controls that I have as well. The problem is most likely the damper that controls the flow of hot and cold air into the car. The motorized component of the damper is most likely not working and its stuck in the hot air position.

I had mine replaced by a repair shop so I cant tell you how to replace it but it may be something that you can do if you have the time and patience to work on it.

Good luck

i've been down here too myself, and discovered that the temp control motor, located in the bottom of the glove box, which you can access by clearing all your stuff in in and opening a small door.
you can adjust it manually, and see if it changes, if yes, the switch can be defective, as well as the motor, the switch is the most likely problem.
but adjust it manually first.

SOURCE: No Heat Passenger Side. I

Hello: You have a failed temperature control actuator for the passenger air mix door. Remove the glove box and the close out panel under the dash on the passenger side. You will see two silver rods going from the actuators (mounted on the top and bottom of the heater/a/c programmer) Turn key on (engine off) Turn the a/c heater control on. Go from 60 to 90 or 90 to 60 and watch the rods the one that doesn't move is the failed one. The actuator is held in place by two 7mm screws and one electrical connector. When installing the new actuator have the temp set at 60 when you hook up the linkage. The passenger side set at full cold.

Cadillac air condition


The passenger side air temp control has a problem. Check connections at switch. If you have a volt meter you can check the switch for continuity or ohms of resistance. No continuity, replace switch.

Could be that the hvac control module has an intermittent problem or the air mix door control for the passenger side is sticking. Check for error codes (DTCs) using a code scanner, but may not show an intermittent mechanical issue. If you can get at the air mix control on the hvac box under the dash on the passenger side, you may be able to check its operation.
