Heating and AC Temperature and Air Delivery Mode Do

You may have a flapper door actuator bad, such that it never opens to heat position for one side.

My 02 Century has dual temp controls . One for driver for passenger. Make sure you don't have the dual climate enabled and just set for heat on your side and AC on the passengers

An electronic motor controls the temp door. Swap right for left to confirm component failure. Actuate the passengers side and look for the moving actuator

the motor for the passenger side
blend door is shot

Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

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.

fault temp sensors
still can be a worn or stuck shaft flap at the actuators
or actuators is still faulty

Go to heatertreater.net. I bought one for my jgc and now it's working great. It's the blend doors that are broken. My has dual temp controls but it still worked for mine. The only thing is, the passenger side heat and air temp stays the same as the driver's side. Who cares!!!!!! It's warm and a whole lot cheaper than what the dealer costs. It took approx. 1 hour and $120.00 for the part. I paid $20.00 extra for express shipping. It's getting cold in Tennessee.

On a w body car with a single temp adjustment control (not a dual zone) your problem should be a low refrigerant charge. Due to the design of this evaporator, a low refrigerant charge will cause the furthest areas from the inlet and outlet hoses (the drivers side) to not remove the heat from the incoming air. This allows the air on the drivers side to be outside temp but refrigerated on the passenger side. In cars with Dual Zone controls you must not only verify the refrigerant charge level, but also check the mode doors which control the air flow and regulate the temp. To check the refrigerant level do not use pressure gauges alone. Verify a proper charge level by checking the temperature of the two aluminum lines going in to the firewall of the vehicle. With the A/C set to high the temperatures should be within 5 degrees of each other. If not, then there is a charge issue. I hope this helps
