My driver a/c doesnt blow cold air only my

This could be due to a fail temperature ( blend door) actuator for the driver 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

its likley to be the pipe has been riped off or fell off or its the flaps on the heater box its self not opening,,,have a look under the dash to fine any pipes that are off the heater box,,
anyhow, who cears if the passanger gets cold,,, its the driver who needs to keep warm!!!!
unless its the other half? or worse still its the mother in law!!!! ho ho ho!

have the refidgerant charge checked, if its low, it can cause this. There could be a blend door problem, also, but the charge needs to be verified full first.

Stuck blend door under dash.

either the heater rad is chocked up and its not hot all over,or its a flap opening problem

junk it its not worth it one of the sensors that open and shut the door are bad

U will need to replace the pass side air temp control blend door acuator motor.

Same problem as mine has. I just found out that it could be the LH Electric actuator, located under the driver side dash, just about straight behind the radio. I got mine in order so i do not knoe if that is the solution yet. just athought for ya.sounds like this should fix it though.

is the compressor turning on? when you turn thwe a/c? on,
and also locate the low side line on engine compartment and feel if is cold, if it is, then your blend door system is not working,
the blend door does control the cold and hot air coming to engine.
