2004 Grand Prix blower

One month ago, my blower was staying on in my 2004 Grand Prix, even with the key out of the ignition. I replaced the blower motor resistor and that solved the problem.
Now, I have a different problem. When I turn the dial for the fan, I get nothing. The blower does not work at all. Is this a different problem, or do I need to get another blower motor resisitor?

Assuming you know where your blower motor is you can check the motor for power with the switch on and see if you have battery voltage at the connector. if you do then it is a bad blower motor. Most of the time when a resistor goes out it will work on high only but no other settings. with it not working at all seems to be motor. Hope this is helpful.

Usually a break down in the Blower Motor "resistor" the resistor is bad, not the blower may need to unplug the blower motor until you find and install the resistor...your parts store can confirm the right part, and location. Hope this helps.

2002 pontiac grand prix,no running lights,noblower motor,no back window defogger

I've been thru this mess... Replace the ignition switch (not the key portion) located inside the steering column. Don't waste your money replacing the blower motor and/or blower resistor. This is a common issue on this make/model Pontic.

Replace the relay. Look in your owners manual for the location of the relay panel.... should be under the hood near driver's side.

There is a heater resistor module, it is located on the passenger side under the dash by the blower motor. It is a bit tricky to get to but isnt to hard to replace. I just dealt with this issue in May. The unit cost me about 86 dollars from the dealer. But be careful becuase normally the resistor goes due to a short in another component in the syste, so this may not be the complete fix for you. My main culprit ended up being the blower motor.

Good Luck

Blower motor resistor

If you were looking at this from under the passenger side of the dashboard it is on the left side of the blower itself it is a 2" x 4" black block. You will need to have a heat welder to remove this and install a new one since it is secured with heat type plastic rivets.

to guest: this resistor is what applies power to the blower so when it shorts out it will make the blower motor run non stop even with the key out of the ignition.
