1997 Pontiac Grand Prix GT from North America - Comments

First off - even though year built is 1997, mine is a 1998 purchased in 11/97.

Numerous squeaks and rattles - according to the numerous dealers I've been to, this is normal. My Grand Am did the same thing. I just thought improved structural rigidity meant something...

Headlights replaced under warranty due to condensation on the inside - no big deal.

A/C blower motor replaced twice in two years. Once for a chirping noise and second time for chirping and the fact that the lowest two speeds stopped working.

Front brakes squeal - will go to the revised pads soon. Even with the TSB, the dealer says it's normal.

While I'm disappointed with the brake squeal and squeaks/rattles of the interior, I still like the car. Performance and looks are great. I'm concerned about the HVAC blower since it's been replaced once a year for the past two years.

Can you contact me... I am having the same problems with my A/C blower motor with 1 and 2 speeds not working at all. I also have a fuel gauge which does not work when the gas level drops below 1/2 tank. My steering pump has just gone out and I am wondering what exactly that problem is and what is costs.

Overall this car is poor.

The blower motor speed is controlled by a resistor, located behind blower motor. The blower motor has to be removed first, the part number is gm 15304891.

Thanks for posting the info about the blower motor resistor. The fan in my 97 would only work on speeds 4 & 5. I ordered the part direct from GM for about $13 and replaced it in about 15 minutes. I didn't have to remove the blower motor as mentioned above. The only slight difficulty was getting to the two forward screws because they are so close to the firewall. It looks like this might be a recurring problem because much of the green coating on the circuit board of the resistor was peeling or missing which led to the part failure. Hopefully the new part will last at least another 5 years.

I just had the same problem on my 1999 grand prix SE at 42000 miles. The real cause of the problem was the AC condensate drain was plugged causing the green coating on the PC board to peel. Access to the drain is difficult from below the car I got soaked when I removed the elbow. I found that removing the radiator overflow tank (2 easy nuts) allowed easy access to remove or replace the rubber elbow. I think that checking this drain should be a once a year routine maintenance. Thanks, Geoff.

I have a 99 Grand Prix SE. Blower motor only works on 1&5. Sounds like I need to replace the blower motor resistor. Can you tell me where it is located in the car. Is it right behind the glove box? Thanks jscodeblue@aol.com.

Look above the blower fan, you will see the blower fan wire connect directly to it.

I have a 2002 GT with the same problem. Seems like a trend for Grand Prix. I didn't have to take the blower motor off to remove the resister, but it might help as the 2 screws are very tricky to get at. I used a bendable screw driver to get at it. Same problem with the coating peeling and appearing to burn out the board. I would like to know more about the A/C drain and how to clean it out, if anyone knows. Also the passenger side temp gauge isn't working, it is stuck at the same temp not matter where the slider is put. Any suggestions? I have heard it might be a door off the blower that is stuck. But I don't know how to get at it, any thoughts? Thank you.
