erratic temp gauge by argus1

Help!! all of a sudden the temp gauge goes so far to the right - it keeps tach needle from moving. Even when car is off the temp gauge needle stays far to the right, Is is sender problem, or instrument cluster needs changing, Is true milage stored in computer so when instrument cluster with odometer is changed - the true milage changes onto the new cluster?
 
Thanks

how offten has everyone been going through batteries on these cars. i have an '03 sunfire, has served me welll as a commuter until recently. i have had to get a jump start 6 times in the last month and a half and can garuntee that i have not left anyhing on. when i put a meter on the battery i measured .26Amps current comming out. it is possible to have a bad measurement but it also sugests that there is somthing in the electrical system that is pulling a load. I have an appointment this afternoon to get the car looked at, but are there any thoughts on the subject? and has anyone else been experiancing this problem.
 
hoping its just the battery. . .

If its the original battery then replace the battery. About C$75.00 at Costco.
If its a new battery you have a problem. I have a 2002 and had to replace the battery 6 months ago as well.

i lucked out, it was just the battery. had the shop check it out just in case, had new lights put in while it was there, all in all i could have saved some money by getting a new batery myself but i like to stay on the side of caution.

I'm having the same issues with my gauges. My gas gauge has flipped completely over so when it's full, it reads past the 110 mph mark. I also have had the temp gauge wonk out on me where it won't reset properly. My brother-in-law, who's also a mechanic, told me it's the instrument cluster and it's not a cheap fix. There's also a wire box under the frame by the front left tire and all the wiring is rotting on it, causing the issues with the gauges. There's no telling how much it would take to fix since they can't tell how many hours it would take. The speedometer also doesn't reset properly once in awhile, so sometimes my car will zero out at 30, then 40 then 50 etc.. until it hits the point where the needle is buried past 110. Then it takes a few times of turning the car off/on to get it back to 0.
 
Does anyone have matches? Let's all just meet at the Pontiac plant and torch the mother f-ers

Gauges - instrument cluster by argus1

I want to replace my instrument gauge cluster with a used one. I have a 2005 sunfire (digital odometer). I have heard different responses as to whether when the used replacement cluster is installed - is the true mileage of car (as indicated on the original removed cluster) automatically reset that mileage to the used cluster that was installed? Is original miles stored in ECU? Thanks

Your car will not reflect true mileage if you change the cluster.

Pontiac Sunfire GT Electrical issue by scottsbsi

When I start my Sunfire all looks normal. I start to drive and every light on the dashboard comes on saying there is problems with oil brakes etc. When I get to idol again the lights most often go out. New battery and repairshop has checked wiring and is beginning to think the cluster whatever that is. Any suggestions..I can't keep paying them to hunt and peck and get nowhere for too many more hours.. gets expensive
 
Thanks

97 Sunfire - No start/power by tk16

My 1997 Sunfire won't start. When I turn the key, there is no power either. This happened the day after jump-starting my son's Explorer. Last time I jump started another car, this happened. I have checked the wires off the battery to the alternator, starter and ground wires. (I was told to check these " fusable-links?) When this happened before, I was charged over $200 to replace an $8 piece of wire, but I don't know what wire or if it's the same problem. Car will not respond to jump-start. All fusses in both fuse boxes are OK. Anyone know what the problem is or how I figure it out?
