Assume the lightbulbs are ok. Need to get a wiring diagram to trace the electrical system for he lights and to see if both are on the same circuit. Check to see if you have 12 volts at the light sockets. Probably not if the bulbs are ok. Then trace trhe wiring. But also check for ground problems. Make sure no corrosion on battery terminals and ground terminals under the hood.

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.
#78 of 173 Electrical Problems - Odometer
Jan 10, 2008 (8:39 am)
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!

#80 of 173 heater fan issues
Jan 21, 2008 (6:23 pm)
hey folks, i just started to have some issues with my heater fan, sometimes it wirks awesome, and lately it will just kinda slowly stop blowing, and then you kick it and it fires up for a few more seconds, is it a relay or something or is my fan just dead, hoping someone can give me an idea cause i dont wanna spend alot of time working on it while its minus 20

The way you describe it sounds like the fan is seizing (not sure about spelling) up. You have to take the fan out. Then disassemble the fan. Clean the bearrings and fan posts with alcohol rub. Add lubricant that is good for cold weather as well. Reassemble and reinstall. Bit of wrok but it works. Just make sure you have the right lube.Get that at an autopart place. Otherwise yo have to do it again next year.
If the relay is dead nothing will work.

Reverse lights. replace switch on tranny. Assume you have a 5 speed. switch is located in left side bottom of tranny. you have to pull front left wheel. Is easy visible and easy to replace. Old switch in aluminum housing and gives way.. New switch in copper housing.
