The vent actuator has gone bad, you can try relearning the actuators by removing the fuse to your HVAC system for 5 min and reinstalling it or by disconnecting the battery for 5 min and reconnecting it. This will recalibrate the heater/ac vent actuator, if it does not reset the actuator. It has gone bad and will need to be replaced, very common for the actuator to go bad after a few years. The internal parts to the actuators are plastic and eventually wear out or crack, causing them to freeze on one spot.
Thank you for using fixya and hope doing the recalibration fixes the problem.

Would replacing a power steering pump in a 2002 Grand Prix GTP Supercharger cause the SuperCharger belt to break.


No.

The supercharger belt is on the main drive, the water pump is on the accessory drive. Provided that they are both properly installed of course.

2000 Grand Prix GTP supercharger fluctuates when accelerating


There is no wastegate.

Change the spark plugs and pay special attention to the plug on bank 3. Look for physical damage on the electrode...cracked, bent etc.
Use Autolite 605's copper core gapped to .055" and NEVER run less than 92 octane.

I have a 2002 Grand Prix GTP and i am having trouble with the supercharger. Most times only getting 1/2 boost on the guage and it runs like a regular 3.8l - the supercharger will ocasionally kick in but...


Check the vaccuum lines to the super charger boost control valve located on the back of the supercharger closest to the air cleaner opposite the pully. If you are not getting vaccuum to the boost control colenoide follow the vaccuum hoses back to the boost control switch and check for engine vaccuum at the switch.
