Question about 1996 Buick Regal Olympic Gold
Only the drivers side , on all positions only blows cool air out.
You need to open the vent assembly and clean up your direction flap that controls the vent direction. Also the seals that block air may be broken and letting air in vents you don't want cool air into. You can replace the seals with insulation tape made for doors. the very thin tape. good luck

Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

this problem is caused by a defective air temperature control blend door actuator motor, it is about center of dadsh in air ducting, it moves the door that diverts air for cold from ac or hot from heater, you must remove the dash to repace it, about a 15 hour job fotr a home mechanic with a factory repair manual, nearly imposs without one.

Hello. The side that is not operating properly has a bad temp door actuator located up under the dash. I am assuming this vehicle has driver/passenger(dual)climate control heat and cold settings. This is a very common problem on these vehicles. Hope you find this information useful!

I have the same problem exactly, if i turn off the ignition and then turn it back on it begins blowing cold air again. I would like to know what the problen is as it sounds like it is not unique to just my vehicle.

Your heater problem is more than likely a bad temp door motor.The seat heater problem is probably one of your elements.Either back or bottom.If your switch light is coming on then the element is bad.

I had the same issue on my 2005 Bonneville, and found that several other GM vehicles have the same problem. If you have Climate controls for driver and passenger, the first thought is that it is an actuator or actuator door problem.
But, it's most likely that you are low on freon. Your system only has about 2-2.5 lbs of freon. You may only need to add 0.5 lb to get cold air back on the driver side.
Of course, this means that you have a slow leak that will need to eventually get fixed. My leak is slow enough that I have to add 0.5 lbs each 4 weeks.
