#110 of 216 2004 Pontiac Grand Prix Blower Problems by KAY65

Dec 17, 2008 (10:51 am)

I have a 2004 Pont GP. My blower will not shut off even when the engine is not running. It will only blow on #5. I have pulled every possible fuse in both electrical panels and nothing shuts it off. I took it to a mechanic and the only thing that he could do was to disconnect the blower all together. Now, I am without heat & window defroster which is a necessity. Please give me the magic CURE that's not going to cost an arm and a leg. Thanks in advance.

1st the ignition switch would not go back to the off position but I'm able to stick a screwdriver up the hole under the column..works good
2nd gas gauge freaks out..up and down..have to watch my trip odometer
3rd the radio digits go haywire the come back
4th winter and I freeze windows up on inside
5th blower doesn't work..managed to " unthaw " it and worked..sort of
6th now it only works in the 5 position
7th Sell this 2001 Gran Prix???? Kinda depressing

I am currantly experiencing the same condition with exact automobile and have come to learn the problem is called blower motor resistor. Thats what NAPA autoparts use for nomenclature. Others call it a module. Price ranges from 65.00 to 100.00 at dealerships. The fasteners used are metal rivots which does not replacement as easy as i had hoped since it's 15 degrees outside and i have no garage.
 
hope this helps and you are able to enjoy the holidays.

Careful!
 
Although, apparently, the 2 things that are the most common to go bad (eg., the blower motor itself, or the resistor, just outside the blower), many people went & bought the resistor, only to find they spent money for nothing, as this wasn't the cause.
 
Don't install the new resistor,...just , carefully, plug it in, to see if this fixes things (that way, you can retiurn it for a refund, if it doesn't!).
 
I haven't had air/heat for 2 years (but live where climate is bearable).
 
And, same as most: fan speeds stopped working until only #5 setting would work,...but then, not even that!
 
It should be asimple fix (anyone know how to test the body control module, without removing half the dash???
 
There must be a way of feeding getting the blower to work, & still send power to work the neccessay vacuums, other necc systems for air/heat, without fixiing the ignition wiring (it's a BIG job!).

I have a 2004 grand prix gt.When I start the engine and turn the heat on the blower will only come on after about 10 minutes of driving.The blower works fine once it's running but if I shut the car and restart then I go through the same thing again.

I got tired of dealing with this problem so I took it to the dealership. They said that it is a common problem with the Pontiac Grand Prix. After inspection, it was determined that the Resistor shorted out the Blower Motor. Both part had to be replaced. The dealership cost of the Resistor Module $92.80 and the Motor $164.10. Labor $273.74.
 
As for over heating... More sure that you are using GM Parts ONLY!!! Other brand parts for this car causes problems. Stay out of Advance & Auto Zone!!!
 
Good Luck!

OK... this morning I turned on the heater and it started out being normal then started reducing in speed. I then went to the different levels 2,3 4 and 5 with the same results. At level 5 it was blowing at level 1 speed and finally quit entirely. Is it the motor or relay or aliens.... 2003 Grand Prix GT, 162000 miles.....
Thank you
