1999 Oldsmobile Intrigue: gls 3.5L..driver side vents..Passenger side

Resolved Question:

I have a 1999 Oldsmobile Intrigue GLS 3.5L engine. It has dual controlled air for Driver/Passenger. The driver side vents are blowing hot air and the Passenger side is blowing cold air. Both sides are set to 60 degrees. All fuses are good. What can be the problem?

Sometimes you can tap on them and they will start to move again, (like the one in my girlfriends 99 pontiac) A new one would have to be bought from a GM dealer and they are about $85. Being it is an electronic part, I don't recommend using one from a salvage yard, thanks

Reply to Super mechanic's Post: Right under the dash there is a little black box with wires connected to it that looks like something should plug into. Is this it?

Yes, that should be it. Right under the dash, around the middle of the heater box.
