...I own a 2001 Pontiac Grand Prix The AC blows hot in summer the heather blows cold air on winter we can seem to find the problem to this deal ...when i turn on the ac the lights go off also. I have changed the switch and the resistor twice before it use to do it whenever it wanted to now is not doing the functions that it should ..AC or heather only air comes out the light on the AC button doesn't turn on either..I would like GM to recall these problem since it's a big problem not having air conditioner and heather when you supposed to.

Blower motor will only work on level 5 on switch, doesn't work at all on 1 - 4 levels, haven't had it looked at yet, hoping it isn't a big cost job. Hoping it may be a sensor, has anyone else had this problem?

Grand Prix GT 2DR Coupe V6 Non Supercharged

  • Automatic transmission
  • 81,000 miles

The Blower motor with the heating unit, will only blow hot or cold air, if it is on the high position(5). Not other selection works (1-4).

Is this happening to anyone else? A real pain in the as* due to the summer months and would like the ac on a little, not full blast you can hardly hear the radio. And in the winter months its great, until your skin wants to peel off your skull due to the excessive heat. I'm hoping its a sensor or something small.

When I start my car and turn on the heater, the blower does not come on. I live in -35 weather for 5 months out of the year, I need a fix for this problem
