Replying to: casey60 (Dec 01, 2007 9:16 pm) Problem was the "back up" switch mounted on the tranny. Easy to get at. Pull the left front wheel and you see a wiring harnass going to the tranny. Problem is that the alluminum housing gives away on the switch. Switch still will read ok on ohmmeter. Replace switch!! And problem is solved. |

Hello. I have a 99 Pontiac Sunfire. This week I noticed when I started my car on Monday morning that my odometer was gone! Its digital and it disappeared. It remained gone till Tuesday morning when I arrived at work. Luckily, I was going in for an oil change that day and I talked to the mechanic there. He was very curious about the year of my car and mileage. He proceeded to tell me that in one week he had two Pontiac Sunfires come in with electrical problems. One of them had to be sent to a salvage yard. He found out that GM decided to save money when making the cars and used aluminum wiring with just a copper coating. The wiring gets easily damaged and corrodes very quickly. He said that once you start having electrical problems it will continue till your car is no good. He suggested that I get rid of it as soon as possible. Has anyone heard about this? Or have experienced the same electrical problems? And today my odometer is gone again! Will it return I do not know. Good Luck with your cars! |

Just bought a 2000 pontiac sunfire SE last week, lucky me. Got it for a pretty cheap price, especially since it has 160K on the odometer. Runs fairly sound for the mileage and the engine is in check. However, aside from routine repairs like getting a couple blinkers replaced, I have found that my instrument cluster panel (i.e. all the guages) does not light up, at all. Additionally, neither does the odometer. I had it checked at a pontiac dealer garage (yea, expensive but they know their stuff) and found that they need to rip into the dash and rework computer/wiring behind there-- total cost of labor and parts: over 500 (total divided equally between labor/parts). Naturally, the quote was declined because I am merely a college student on limited funds. So, all that was done was that the computer was reprogrammed and they said that it will work now, but that it may shut off at any time in the future. In other words, I probably need to tote along a flashlight in the car at night "just in case." Question is: has anyone else had an issue such as this? If so, where did you get it fixed and how much did it cost you?? I personally think I am getting screwed in the whole matter, at least with repect to the labor costs.

I have a 97 Pontiac Sunfire SE. My left signal light went out, so I had it replaced. Just a day after, it stopped working again. I put a new bulb on Thursday, and now, Saturday, it's busted yet again. It has a burnt smell, and the plastic at the bottom of the bulb seemed to have melted. What could the problem be? Any input would be much appreciated! Thank you! (By the way, I went to Autozone, Advance Auto Parts, and O'Reilly, looking for a socket, just in case that would solve the problem, and none of them carry the left signal socket.)
