Heater Controls Dont Work

Post by NocturnalZ26 »

I just picked up a 1997 Grand Prix GT. Well the heater blows out of every vent. I put it on the feet or vents and it dont change to that. My beretta i had did that once but i forgot what it was i thought it was just a hose disconnected.

Beretta was likely the vacuum hose that lays under the battery tray.


Mostly you meet friends when traveling by accident, like by sitting next to them on the train, or in a restaurant, or in a holding cell.

Could be the heater control valve. If it's not a vacuum leak as said above.

It's a vacuum line busted or leaking. Start by the battery tray. Or from the CC unit. CC unit and vent change are almost run by the same set of lines on GM cars.
