I have a 96 STS, the two passenger side vents always blow cold air even if the heater is on and the drivers side is hot. The Passenger temp control does not seem to be working but you can manually reach in from under the dash board and turn the control so that it changes the temp on the pass. side. Would this be a problem with the the temp control itself or mechanics under the dash?

Most likely the actuators under the dash. Try running the main temp control all the way up to 90, then back down. That seems to excercise a sticking actuator and free it up sometimes. Also look for cracked or disconnected vacuum hoses while you are under there.
