Re: 1995 Grand Prix (teal in color). The "knob" on the dash panel that controls the positioning of the air in the vents is broken. Where can I get a new one? Also, the glove box latch broke and I am unable to find a latch. Any help here? Oh, the car runs fine!

C Craft, it could be a couple of different things but from what you stated my best guess is it's going to be a issue with the door that diverts the air to the position that your selector knob is in on the climate control on the dash. If you can turn the selector knob and actually hear the actuator moving the door but the air doesn't change vent positions, then I would say the door is broke.
Now, you also want to check and make sure that there is vacuum going to the control. The main vacuum line coming from the engine is located around the passenger side firewall under the hood. Make sure the line is not broke or come unhooked. You can pull the control head out of the dash and actually crank the engine and check to see if it's getting vacuum that way by unplugging the vacuum line assembly from the back of the control head. If your getting vacuum to everything, then it will have to be a problem with the door itself which is in the air box behind the dash and it is not a easy fix. I would suggest having a qualified mechanic look at it if what I have told you don't check out. Hope this helps you.
what position is the control switch in? does this occur when accelerating?
the door that directs air flow is controled by a vacuum motor. the default position for the door directs air flow to the defrost vents in the event of vacuum loss to ensure the windsheild will be clear of mist. if there is a small leak, vacuum will temporarily be removed when accellerating and the motor will revert to the default position. there are vacuum lines from the control knob to the motor you must check these lines for leaks. the diaphram in the motor may be bad. also check the main vacuum supply line to the control knob. usually red in color. if there is a vacuum storage cannister. it may be leaking. this cannister will maintain vacuum for the circuit when accellerating. engine vacuum decreases when accellerating.
The vacuum switch is right behind the mode control knob on the climate control panel, but make sure it is getting vacuum from the engine before replacing it. There is a vacuum line that goes from the engine intake manifold through the firewall to the control panel. This line may have come loose from the engine, which is the most likely cause of your problem.
If the blower is blowing air just fine, but you cannot control the temperature, you need to listen to air coming from the vents while turning the temperature from hot to cold. If you do n ot hear any change in airflow, then you may a temperature door in the dash broken. this is becoming a common problem on the Equinox
linkage inside dash or relay for electric front vents went bad
linkage sometimes comes off its holder from usage this is normal there only held in by a upin under the dash
if electric the relay for the the top vents needs replacing this i believe will be with rest of the relays in engine compartment
