#4369 of 4431 Re: 2001 Gr Prix Air Conditioning [tncarman] by cnw Jul 09, 2007 (1:12 pm)
Replying to: tncarman (Jul 07, 2007 10:22 pm) If the car was still under warranty, I would agree. However, in this case another dealer won't repair damage resulting from the first "fix" without wanting compensation; justifiable expense on his part. It appears you have to appeal to the dealer's sense of "honor" and his commitment to provide customer service--both of which are increasingly hard to find. Failing to get the dealer to respond to a sense of duty, you may have to respond with "Better Business Bureau", Chamber of Commerce, or "action line" through a local media outlet. Good luck!!
#4370 of 4431 Dual zone climate control problem by omegax Jul 13, 2007 (2:30 pm)
Ok i have a issue that doesn't make sense to me. I have 2001 grand prix gt 3.8l with dual zone climate control. Now the problem is this. well there is a leak but thats not what's concerning me at the moment. When i turn on the ac the passenger side blows out cold air.....the driver side blows out warm air. I have no idea what's going on at all.   posting to see if anyone else has had this problem and/or has a solution.   Thank you for your time Replies to this message: druvie (Jul 19, 2008 7:14 pm)

Replying to: dziegiel (Jul 03, 2001 6:49 am) Did you ever find a solution to this problem? I have a 1997 GP where the alarm is going off every 24 hours (around noon every day). It beeps four times and then quits.
#4372 of 4431 2001 Gr Prix GT Odd Problem by grprixluvrgal Oct 01, 2007 (10:17 am)
I have no idea how to explain this one. It started shortly after I got the car in 2004 but only occurred at one specific time when I was backing out my drive. Now it's happening a lot more. What it is is this: Originally when I started my car, put it in reverse and started backing out the drive, something in the front of the car (engine, brakes, steering, ???) makes a kind of humming/grunting noise that vibrates slightly, lasting a few seconds. Now it happens more often but intermittently when I break, am steering into a turn, or sometimes just driving straight down the road. It's loud enough people can hear it and stare. I don't know if this is connected, but sometimes my low track light will come on for no reason. This has happened maybe 3 or 4 times when there is no reason for it to come on, such as starting to back down my paved, even driveway. I tried driving with the track off, but it had no affect on that strange noise. Any ideas?

Replying to: grprixluvrgal (Oct 01, 2007 10:17 am) I believe it is somehow connected with the ABS and its sensors. Don't have any thoughts regarding the current frequency of the sounds, etc. However, the initial sounds and pulsing after start-up are normal for the ABS as it initializes itself. I have no experience with having an ABS that needed repair or service. How is the brake fluid level? Do pads/linings need replacement? The "Trac" light comes on becuase it is tied into the ABS; it applies braking pressure to the wheel that has slippage. Keep us posted.   Clark Replies to this message: grprixluvrgal (Oct 16, 2007 8:07 am) cnw (Oct 17, 2007 6:17 pm)
#4374 of 4431 Re: 2001 Gr Prix GT Odd Problem [cnw] by grprixluvrgal Oct 16, 2007 (8:07 am)
Replying to: cnw (Oct 07, 2007 5:26 pm) That was my suspicion as well, even though I know practically nothing about this stuff. I have not checked the brake fluid level recently. I just had all the rotors and pads replaced a few months ago, so I don't think that is the problem.   I did, however, take my car in to have the tires rotated and Belle Tire told me I needed a new right front hub assembly. Could this contribute to the problem at all? The vibration and noise is getting so frequent now it happens more time than not.   Thanks for the info and I will check the brake fluid level when I get home tonight.

Replying to: grprixluvrgal (Oct 16, 2007 8:07 am) You may have two separate problems: front hub assembly could certainly cause the constant humming and vibration; ABS/TRACS system could cause some of the pulsing. You're right regarding the fluid level--you certainly wouldn't expect a problem there since you just had a brake job done, unless....? Clark
#4376 of 4431 Re: 2002 grand prix starting problems [chambo1] by mazuur Nov 21, 2007 (2:39 pm)
Replying to: chambo1 (Jul 12, 2006 10:32 am) I have a 2000 GTP that had the same problem, I replaced the fuel pump resistor, didn't fix the problem, I replaced the crankshaft positioning sensor, didn't fix the problem. So I bought factory service manuals, I paid less than a hundred for it, the manual is easy to read and diagnosed the problem the first time through it. My starting problem was cause by the mass flow air sensor starting to fail in the throttle body (manifold). If the computer detect decreasing air flow it tries to compensate by decreasing fuel delivery and when sensor completely fails the computer stops fuel delivery completely. I hope this helps, I've been where you're at and it ain't no fun. John

Replying to: grprixluvrgal (Oct 01, 2007 10:17 am) I am having the EXACT same problem with my 2004 grand prix. I've had a couple mechanics look at it, and they can't quite determine whats going on. Today I'm taking it to the dealer. Did you find out wha the problem was??   Thanks, Christi Replies to this message: dgw7245 (Dec 05, 2007 6:00 am) wbeard6 (Jan 12, 2008 10:58 am) turtleshark (Mar 31, 2008 9:20 am) headach (Jun 25, 2008 4:22 pm)

Replying to: chriistii (Nov 26, 2007 8:54 am) What did the dealer tell you? I am having the same exact problem on my 04 GP as well. And this morning my ABS and Traction System lights came on. I have also had a couple of instances where the same "humming/vibrating" noise would happen pulling into a parking space while turning to the right, Replies to this message: wbeard6 (Jan 12, 2008 10:58 am) turtleshark (Mar 31, 2008 9:20 am) headach (Jun 25, 2008 4:22 pm)
