1994 Pontiac Grand Prix blows cold air on feet

I have a 1994 Pontiac Grand Prix, when the air conditioning is turned on, the cold air blows at your feet. I have torn the interior of my car apart in search of the problem and to this point I have been unable to pinpoint the problem. However, I think that there is not enough vacuum to control the air mix motors, because there is more than one motor that doesn't work correctly. There is an electronic devise that appears to produce the vacuum for these motors. How much vacuum should this produce? Could this be defective? Is there a way to check it?

2005 Grand Prix heater works fine when blower is off-air coming thru vent gets hot; once blower is turned on air turns cold. Why?


Sounds like a clogged heater core- insufficient coolant circulating through heater core, and as soon as you blow air past the core, it get cooled off.

Air Conditioning


I'm going to assume the fan louvers (that direct air from wind shield head to feet ect) are electronically controlled. If that is the case, then a motor may have died. You only have one AC system for the vehicle, so if its cold on one side, then the fault lies within the air ducting system. Maybe a mouse built a nest in there and is blocking air flow?
