Re: Heat blows hot on passenger side but cool on driver's...
Most likely it is the climate control unit. Had the same issue with my 99 Regal, replaced the climate control unit and haven't had any issues since. Might try Digital Dash Solutions on eBay, they will ship you a refurb at1/3 price of buying from a dealer if they have one available. If not, they also have a climate control repair service. I'm not certain that they fix Pontiac products, but it wouldn't hurt to ask.

Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.
have someone check the driver's side temperature control doors, in behind the radio. there are two push rods attached to a plastic piece. the connector on one or both of these push rods, become unattached. leaving you with cold air. once that temperature door is closed you get hot air. passenger side still mixes, but not drivers. All or none for heat on Driver's side
There is a damper that controls whether heat or cooling or somewhere between that is controlled by the temperature controls. A separate system is controlling the passenger side and the driver side heating and cooling. I hope this is still under warrantee. If not it might be a big job to diagnose whether the problem is in the heat and cool controller, the wiring or the damper device. I hope this helps.
Hello, this is cused by the drivers side temp door actuator. there are two electric motors that move the temp doors from cold to hot. there is one on the drivers side and one on the passenger side. you will need to replace the one for the drivers side.
Remove the left instrument panel (I/P) insulator.
Remove the knee bolster bracket bracket. Disconnect the electrical connector from the left air temperature actuator.
Remove the mounting screws from the left air temperature actuator.
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!
Is it leaking antefreeze?
The thermostat might be gone or needs a bigger thermostat
It could be a vaccum leak for the drivers side blowing cool air and the passenger side blowing warm air
Does it have dual air control switches one for drivers side and one for passengers side?
