Question about 2005 Chevrolet Cavalier
Last December, my analogue gas gage quit registering correctly. It sat on empty for about a week, then jumped to half a tank (even though I had added no fuel). After it moved to half, it would not reset to empty when the ignition was switched off. When I cranked the car again, the gage jumped to full. The next time I cranked the car, the gage went on past full, half way on around. I thought the trouble might be some water in the lines, so I added a fuel treatment. No success. Eventually the gage worked its way back down to empty, but it hasn't worked as it should since. Soon after, and only on colder nights, my speedometer would not register. After about twenty minutes of interstate driving, I have to make a series of stops. The speedometer usually begins to work after these stops. Strangely, letting the car sit and idle for five or so minutes has no effect. Next, my headlights began to jump from regular low beam to the default Daytime Running Lights. From time to time, the service light will come on. It always goes back out when the ignition is turned off. The problem with this is that I work at night and when the service light comes on, the headlights will go out if only the DRL are on. Neither of these problems occur if the high beams are on. The next problem I noticed was that when I signal to the left, the cruise control (if in use) will switch off. This does not happen on a right turn signal. Now my engine temperature gage is not working. It will not reset when the car is turned off. It has now gone past the temperature redline almost all the way around. All of the problems began or only occurred on cold or rainy nights. However, all of the electronic warning lights and the tachometer still work. Any ideas? I don't want to take this to a dealership and either get ripped a new one for them to replace a simple relay that I don't know about, or buy an all new panel only to find that this does not fix the problem.
What kind of a rip off is this? We can help fix your problem for free, but if you really want a solution you're going to have to ante up $10 plus. And, by the way, if you fixed it without our help, how about telling us how you did it so that we can charge the next unfortunate soul with the same problem for the information you have provided us free of charge. Really, FixYa, THANKS FOR THE HELP.
