Assuming it has duel temp controls, one for the driver and one for the passenger, one of the temp blend door actuators has failed.
heater hoses might have been disconected
wash your hair with cold water... and when its dry.... blow dry it(but with the cooler on...so cold air blows out) ive done it myself! :D
The dual climate control unit is malfunctioning. Most likely the soldered connections on the temp slider ar loose. You can purchase one from eBay for less than $50, and installation is very simple.
I had the same problem on my 2000 Bonneville, its low on refrigerant in the AC cooling system which means it has a leak somewhere. Have the pressure in the AC cooling system checked by a professional. They can inject a dye into the system and check it with a black light to find where the leak is and fix it.
No, Cold is not a Christian band.
There is a differential vane in the AC ductwork that regulates the flow of hot and cold air into the two halves (driver/passenger) of the system. Failure of this mechanism is one of the more notorious problems with the LS.
make sure both knobs are all the way up on red for heat...
One of the temp blend door actuators has failed.
Had the same problem. In my case it was the actuator motor inside of the panel in the passenger footwell. Check to see if the flap is binding or it is the actuator motor itself.
heater control valve is bad on the drivers side.
MY WIFE TOLD ME: THAT HAPPENS WHEN THE AC SYSTEM IS LOW IN REFRIGERANT, (IF SHE SAYS THAT , IT'S TRUE )
When my a/c system is low on refrigerant, it blows hot on drivers side, cold on passenger side of the dashboard. This is a 1997 Buick Ultra. Recharging the system solves the problem.
Dissconnect the battery for 1 hour and reconnect, should re-set the flaps!
get a new car. or better a new air con stupid
the problem is a part called the air temperature control blend door actuator motor, it is deep inside the dash and the dash must be removed to replace it.
Check the following items............... 1. A/C heater controller. 2. A/C heater controller doors.
My 1998 Intrigue did the same thing after battery was replaced. Found the answer online. Turn the AC and car off, disconnect the battery, wait 5 minutes, open both front doors, reconnect the battery, start car, turn on the AC full cold. This resets the computer and the AC works perfectly!
