2003 Pontiac Grand Prix: headlights failing or too dim

Filed Apr 1, 2016 · Electrical · 110 miles · MO

While driving on the highway head lights went out, heard a very loud pop as if something burst, no longer does the rear defroster, air conditioner, heated seats, or information panel work. Running daylights no longer work as well.

There were several problems with my car beginning with rear defrost not working. The air would only work on high. Then as I was driving home one night I turned the fan to the air/heat off and my headlights went out nearly causing me to run off the road. Then at some point my car would not start and I would have to keep trying. Then it would not start at all. At first I was told it was the starter so I had that replaced, only to find out it was not the starter. Finally the problem was solved amazingly enough it was the ignition switch. There should be recalls on all these vehicles before more people are injured or killed because of a faulty product.

While I'm personally unaware of any crashes or people dying due to this problem on this model, gm has a well documented history of bad ignition switches on other models that are not included in the recall that they have known about for many years. The effects of the bad ignition switch with this model are: 1. The A/C - heater fan blower works intermittently, if you're lucky, and then only on high speed if it does. None of the other speeds work at all. 2. When you try to turn the fan motor on to run the heater or A/C, the headlights go out. While there are different schools of thought on the cause, after researching the internet, one component seemed to correct the problem every time. You must replace the ignition switch. The problem is not the resistor as some seem to think, but the ignition switch. Those who replaced the resistor always had to come back and replace the ignition switch. Those who replaced the ignition switch had fewer, if any, problems after that. I write this to you because I believe someone "up there" needs to know this information. I simply hope it doesn't fall on deaf ears like most things. I withhold further comment. Regards, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

When I turn on the blower switch, the blower doesn't work and the headlights go out. It mainly happens on the lower speeds but occasionally happens on high speed also. It is intermittent but happens around 75% of the time. This has been going on for about a year. I have checked all fuses and relays that seem to be related and find no problems there.

I have a 2003 grand prix se and everytime I turn my AC/heater on my headlights go off, its 80+ degrees in the summer time. I can't keep driving with my windows down its too hot, not to mention I carry my friend and her kid around. I worry every night driving down the road that my headlights won't work. This is very dangerous for me and other traffic. I've read many forums and websites containing people with the same exact problem. Please make a recall. I've been told it the ignition switch and blower.

In feb of 2003 my pontiac grand prix caught fire after I parked for the evening. Since then, insurance refused coverage for "suspicious in nature. In 2003 pontiac claimed no responsibility, gm's 100,000 mile warranty was a refused. After complaining again in 2006 pontiac called again to say they were not at fault and had no responsibility. I asked them for corresponding VIN numbers and was refused. I have located over 15 additional grand prix engine fires where gm / pontiac is claiming no responsibilities. Once ? Twice ? 10 + ? I read that the federal safety agency had begun another investigation in feb 07 and would like more information on this. I would be happy to forward copies of any of my materials including 2 separate fire investigations that claim my fire started by the drivers head lamp under the air filter assembly, including receipts that show where gm serviced my fuel assembly 2 weeks prior to the fire...

I constantly get flashes of high beam from oncoming drivers when driving at night when I have my low beams on. Also, when it rains, the passenger side leaks water under the dash.

While driving a 2003 pontiac grand prix gtp tried turning on the dash lights at dusk only to find that the dash lights as well as the head lights low and high beam would not come on. After having the dealership look at the vehicle it was found that a plug came loose causing the loss of both low and high beam lights. I find that this could possibly be a safty hazard and fill that the low and high beam should be on separate circuits so as to not loose both lights at night.
