2004 Pontiac Grand Prix air fan not working at all

Yesterday monring I started my car to leave for work and noticed the fan did not work at all. I could hear the a/c working, but no air was blowing out regardless of the speed or vent setting. I looked at the fuse box under the hood and the only fuse that is blown is listed as "battery main 4". It is size 30 with a pinkish looking base. I have no clue if this has anything to do with the problem, but I went to Autozone to attempt to replace it. I purchased a Bussman Female Maxi Fuse 30. It looked exactly like the one I was replacing but it would not fit in the box. No one at AutoZone could figure it out so they gave me a refund. It rained extremely hard the night before so I also wonder if that had anything to do with it. Also, in the days prior to it quiting, form time to time there was a whistling noise coming form the fan when it was turned on. This noise only started after I got it back from the dealership.

My car was in the dealership shop from March 9th - April 10th because I was rear ened. I have had nothing but problems ever since, including soaked passenger side floor boards(front and back) just a few hours after I got the car back. It rained that afternoon and water myteriously came from underneath because nothing else was wet (not the doors, windows, seats, or any area around the floor). The dealership said they could not figure out where it came from and kept implying that I left a window down.

If anyone can help me avoid going to the dealership with the fan issue that would be great.

Hello nathan...GM issued a service bulletin for the blower motor problem, i will post if for your reference.

GM Service Bulletin No.: 05-01-39-001A

Subject:
Blower Motor Inoperative or Intermittent, Blower Speed May Drop or Blower Continues to Run After Key Off (Install a Capacitor at Blower Motor Control Module Connector)

Models:2004-2005 Pontiac Grand Prix

Condition
Some customers may comment on an inoperative or intermittent Heating, Ventilation and Air Conditioning (HVAC) blower motor. Others may comment that the blower motor speed may momentarily drop or that the blower motor continues to run after the key is turned off.

Cause
This condition may be caused by a voltage spike from the wiper motor. The voltage spike may cause a logic lock up in the blower motor control module that may be either momentary or permanent.

Correction
Install a capacitor at the blower control module connector.
DO NOT replace the blower control module, blower motor or the HVAC Control Head

Call your dealer and get some feedback, see if they mention the service bulletin (which i doubt) if they don't, bring it to their attention that you are aware of it. This could possibly cause a fire and needs to be corrected.
The blower motor fuse is the square pink fuse second from the left. Take the blown fuse to NAPA and match it up. If it blows again the blower motor or the blower resistor is shot.

The blower fuse is the pink one second from left.
Let me know how it goes, if the blower works and sounds ok, not making any abnormal noise it's the resistor, i can help you with that.
Good luck...i hope this helps.

Take it back to the dealership and tell them that you are having issues with this things and that they need to fix it now. I know you want to stay away but this is there problem and they need to fix it and pay to have it fixed, not you. If you do not want to do that. Then you go to the dealership and see if they can get you that fuse. That fuse controls your A/C so you need to get another one for it to work. But that doesnt explain water and other things

Check for a vacuum or air leak. Possibly a hose or intake manifold. Odd that it runs better on default MAF settings with MAF unplugged, but if no codes indicating a circuit problem, IDK. Could be a vacuum leak.

Yes that is what the code means. GM usually uses two, one that makes the gauge work and one that tells the ECM what the engine temp. is. You need the one for the computer.

My a/c will not blow any air in my 2004 pontiac grand prix when i turn it on i hear it click but no air will go thru.


Sounds like the blower motor is seized if you here a click it is most likely the relay. you can remove the lower panel on the passenger side and tap on the blower motor with the key and the blower switch on it may start working again
