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!

#119 of 216 Heater fan by mkn1

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

mkn1 continuation:
In reading this forum further there are a few more symptoms;
I no longer have to depress the brakes to shift into gear.
There has been times that my radio display flickers.
I can't get my ignition key out unless I physically release it by going under the steering column.
Any help would be appreciated.....

#121 of 216 blower motor problems and ac problems by auauau

Feb 17, 2009 (8:35 pm)

so we know that the rain draining on the passenger floor could be the caused of the problems to the wiring and possible the blow motor had same issues except that when blower was working for me that 1 to 4 was working and the 5 wasn't on occasion, also don't know about my lights if they were woking when the blower motor was working I have one of my fog lights out but seems all my lights are working when the blower isn't as I took a look tonite tried various things but no blower tried turning over ignition playing with the wiggling the key lock to see if it was a short to see if blower would come on it didn't. It seems that had difference with other peoples problems which I may think it could be the blower. I checked all the hoses to see if was running hot seems all of them were also changed thermostat wasn't the problem checked fuses under hood they seem all ok not to sure about the relays also took a look at the blower itself looks like water all over it from rusty water marks from the rain and probable washing the vehicle. Cause everything is fine except the blower and also had the dimming and then ok on occasion within a split second or two so anybody have sugestion on that problem? a 1997 grand prix GTP model

#122 of 216 Trouble with my 98 Grand Prix GTP heater/AC blower motor by az_98gtp

Mar 07, 2009 (6:17 pm)

Hello there, I am having trouble with my 98 Grand Prix GTP heater/AC blower motor. To begin with, I was having trouble with only getting heat from the passenger side vents and cool air on drivers side as well as my blower motor was having extremely loud screeching noise coming from it. I still had all 5 motor speeds the best I can tell or remember.
 
After hunting around for answers on the Internet at different web sites, I found this link saying to change the left/right side door actuator. http://www.w-body.com/forum/index.php?topic=41201.0 After taking my actuator out and finding the gear was broken like shown at the link, and thought I had myself a quick fix and ran down to the local wrecking yard to get a good one.
 
I replaced that and proceeded to fix the blower motor noise. I took the motor apart and cleaned and oiled the bearing on it and put it back together. After I plugged it back in, the blower motor would only turn on for a few seconds and then turn on for a few more seconds real soon there after. It does this every time I turn on the heater control and shut it back of again. I have tested 12v to the motor and it does run just fine.
 
I proceeded to replace blower motor control module and still no luck getting the blower motor going. Also I do have heat in my seat, HUD works fine and no other noticeable problems besides the blower motor not coming on.
Is there a way of resetting the system in any way at all?
PLEASE help! Thanks!!!!
