Why with the heater on does the 1999 Olds Intrigue blow cold air through the drivers side vent while hot air blows through the passenger side vent?

There is, I think, a TSB on this condition that says the temp control door inside the dash air box warps over time and causes it. Common problem. The culprit is a design flaw in the temp controller, admitted by a GM engineer I spoke with. The sensor gets "confused" with the temperature in the car and decides the driver needs heat. The system diverts a flap that routes warm air and AC to the driver, while the passenger side gets only AC. If you can stand it, the system usually adjusts correctly after several minutes. There are several reset sequences floating around the net, such as pulling fuses, disconnecting the battery, leaving doors open, etc.. None of these worked for me. I have found that avoiding the "auto" setting by turning on the system by first hitting the outside air button, then the ac, then adjusting the fan brings the system up correctly, especially on a hot day (thank goodness). Make sure the driver temp is turned to 60
