Has anyone had this problem? Could it be a va*** line not opening a damper to drivers side? How about the console itself? Any idea`s!

 

Unlikely, need to know year and model you are dealing with.

 

I have that same problem in my 1996 Cadillac Seville STS can anybody help me with this problem????

 

i have the same problem on my 98 sls with it only being hot on the driverside and i basicly removed the automatic door contol box for the passenger side and opened the door to make it only blow out hot air. this is only a temp fix. but lately im having the problem where the air only blows out through the vents and it wont change to anything else.

 

Cars with "Dual" hvac systems(passenger side temp control) use electronic actuators to direct air flow. Many times actuators will set error codes - door position does not match commanded. So check for codes. Daddylac sounds like mode actuator concern - it can be somewhat viewed above gas pedal. Dash will have to be repositioned or removed to replaced. Temp actuators can be replaced by removing passenger side hush panel and glove box. Older models (non Dual) use vacuum systems and temp issues tend to center around air flow blockage or low coolant / restricted heater core. A/C - low freon.

 

do you think one of my doors are stuck open so it only blows cold air out. its winter and its too cold out in my car haha can someone help i have a 1996 seville sts.

 

Am I likely experiencing the same issue with my 2001 Deville? This is bringing back nightmares from a 1984 Fleetwood I had years ago... Uuugh...

 

i found the problem there is a sensor under the glove box you should see a plug going into a box with a **** on it and on the wire there is labeling saying dual climate control just turn the **** and unplug the wire for a quick fix thats at least what i did

 

Issue started after battery replacement, removed glove box and panel under box.
cannot see anything.
how do you remove radio/heater panels?
