#26 of 38 Fan turning off and on by bobbi209

Jul 23, 2012 (3:07 pm)

I have a 2004 pontiac gp. In recent months the internal fan has been acting up. It will turn off and on on its own and stubbornly refuses most of my coaxing. I have taken it into a mechanic as I dont have the ability to repair it myself at the moment but they keep giving me conflicting reports about what the problem is. So far I have been quoted at 50 dollars for a small fill up of coolant which I was told is not very low and no leak. Then I was told by the same mechanic that it was all my fans and my car would become damaged if i didnt fork over 400-900 dollars for a full repair. I sadly had to burst his bubble on that fact since I know the engine fan works fine as I can check it for myself without removing the dang dashboard. Then yet again was quoted 300 dollars to check the resistor which is now what he swears the problem is. All this after he has ran a diag on it. Is there anyway to get to the resistor under the glovebox without pulling the dash? I do not own a repair manual for this car yet so any help locating it would be awesome! thanks

your problem may not be your wiring, or your blower motor... it sounds like it's in the vent flap system. Your car is new enough to have that system electronically controlled (as on a 1993 Dodge Intrepid I once owned) It may need a simple calibration. On the Dodge you pressed and held three buttons at once (or some similar act) and the vent doors cycled through all their full open / closed positions. It's like calibrating a joy stick on a computer. You set the range of motion of the doors so they know where they're sitting.

I have a 2006 Grand prix. It has a musty smell from time to time. I know the A/C has a drain tube some where, but I can not find it. My 2000 GP had the typical rubber elbow on the fire wall and I could see it and maintain it from under the car. Can someone shed some light on this? Where exactly is the drain for the A/C on an 06, and is there any other things I should check regarding the odor. My car is not at all wet inside, cabin or trunk! Thanks for listening.

My fan does not kick in when Heater /Ac is on, Both AC and heater kick in but no fan, While i drive the car and if i hit enough bumps then the fan comes on, If i turn the dial when the fan is working only high and low settings work,

I have a 2004 Grand Prix and I was experiencing the exact same problem. I did some research and found out that there is a cabin air filter on the passenger side. You have to go under the hood to change it. Once we changed the cabin air filter (different from the engine air filter) the smell went away.

Thanks much. Did so, regarding cabin filter along with finding and clearing drain tube. Seems to have worked. Thanks again.

I am having the same problems with my 04. I haven't taken it to a mechanic yet but plan on doing that soon. Did you ever end up getting the problem fixed and if so what was it and how much was it?
