blower knob

[MAjor94]

I dont know if this problem is comon, but. When you turn on the heater (or any other setting) you can only have it run on 3-5. Settings 1 and 2 dont do anything. Also this summer it was hard to get the A/C light to caome on.

Thanks

Well if it only worked on high it would be your blower motor resistor. Not sure on 94's

I would say it is the resistor.

Blower Motor Resistor is my first thought.

But knowing Make, Model, Year, etc would help.

Im sorry....its a 2002 pontiac Grandprix gt 3.8L


Where do I find the blower motor resistor?

it should be close to the blower motor. im not totally sure. it should be a small black box held in with 2 bolts, and have a 4 wire connector on it.
