#127 of 166 No Dashboard Lights by frames3 Aug 10, 2008 (10:35 am)
Hi all, I have a 2001 Grand Prix and I just recently ran into a problem with my dashboard lights. About a week ago, the dashboard lights started to flicker while driving, and then they turned off completely. Now, when I start the vehicle and turn on the lights, the dashboard lights do not come on at all.   My headlights, tail lights and interior lights work fine; I just checked the fuses and they all seem to be okay. It looks to be an electrical problem, but I can't find much online to help me trouble shoot this problem. Is there anything I can do to isolate the problem? I did read somewhere that it could be a headlight switch? Any suggestions would be much appreciated. Thanks!

Replying to: frames3 (Aug 10, 2008 10:35 am) I had a VERY similar problem on my 2002 Grand Prix. My lights would flicker, like a blinker, when I applied the brake or the dash lights would go out it I turned on the fan switch. I changed the battery and the heater resistor, no joy. Finally after reading this forum, I read about the ignition switch wiring harness causing similar issues on other cars, see reply #77 of this forum I changed it and this fixed my problem... Part cost ~ $127.00 and about 45 minutes to change it, with the correct tools.. Sounds crazy... but it worked!   Stan

Replying to: svill77 (Jan 29, 2008 9:40 am) UPDATE: The problem turned out to be the resistor. Basically the connection point between the power wire and the blower. It essentially 'resists' the electrical current from the battery which is a direct feed. When it fails the current becomes constant. Essentially like taking the blower and connecting it directly to the batter which explains why it wouldn't turn off even with the car off and the key removed. The part if available through AC Delco.
#130 of 166 Crazy Electrical Problems for 97 GP GT by choppedgp Aug 22, 2008 (12:08 pm)
I have a 1997 grand prix gt. I have so many electrical problems ill just start by how i get into the car. I get into the car and with no key in the ignition and no lights on i press on my brake pedal and my cluster lights light up. So thats weird. Now i start the car up. and during the day with no lights on. everything works fine. but when it comes to night time. Or i manually turn my headlights on. My left turn signal stays solid, Inside and outside of the car. And my cruise control doesnt work when my headlights are on. Also when i brake, when the headlights are on, all the dash lights including the digital display and cluster flash brighter. If the headlights are off, and i turn on my turn signal it works, but the cluster flashes with the turn signal. please help me with any intelligent input that anyone has. I dont have a ton of money, so i dont want to spend a ton trying to fix this. please help.

Replying to: frames3 (Aug 10, 2008 10:35 am) I have encountered the same problem on my 1997 Grand Prix and was hoping to find an solution on here. Once in a while they come on for a few minutes. Thinking of replacing the headlight/interior light dimmer switch unit. Sure hope this gets them working again. Will post again if that fixes it.

Replying to: frames3 (Aug 10, 2008 10:35 am) i have encountered the same problem. all the dash lights stopped working. after i played with the switch and wiring harness under the dash the lights for the stero lit up but that was it wondering if anyone bought a new light/dimmer switch, expensive, and if it worked?
#133 of 166 Re: No Dashboard Lights by ayptdp Oct 21, 2008 (3:39 pm)
Have not replaced the headlight/dimmer switch yet. GP quit starting along with fan problem and replaced the ignition switch/harness which resolved that. The dash lights worked on first test following that but now they are out again. Since the HL/Dimmer switch is sooo expensive ($192.00) going to try to bypass the switch to prove that's the problem. May go for used one.
#134 of 166 Date changes in Display by car_ditz Nov 10, 2008 (2:37 pm)
This is driving me crazy ... minor to some but annoying to me. Everyday I get into my 2004 Grand Prix the date appears to be okay, within a couple hours and a couple of starts later date changes 1 day forward or backward. I change it only to happen again, it seems like this recently started happening could it be tied with daylight savings time or is my car not that smart to know the difference?   I love my grand prix but I have put more money into it over the last year that it is now making a major dent in my wallet!
#135 of 166 99 Grand Prix GTP Warning Chimes by meg2good4u Nov 09, 2008 (11:12 pm)
So every now and again my car will chime at me 4 times...while going down the road. It does it more frequently at slower speeds, and when I turn. I find nothing in the owners manual nor online as to what this means. No warning lights come on. Seatbelts are buckled, doors are all closed, antitheft code is entered, plenty of gas, oil is new, turn signal not stuck on....   it makes me crazy when it does it. All I've been able to find is that it happened to a guy with a 97 grand prix a few weeks ago...but he hasn't gotten any answers either.   Help!!!

Replying to: danh6 (Feb 25, 2008 10:05 pm) Dan, I too, are having these identical problems with my 01 gtp. Did you ever solve this problem?
