Pontiac Sunfire Electrical Problems



  • brian1cjbrian1cj Posts: 1
    Hi argus1,

    I've been all over the Internet searching for a problem with a 2005 Sunfire and you and I are (or were) in the same boat. The car does exactly what you describe where the temp gauge (now now the speedo) doesn't reset when the car is turned off.

    How did you resolve it? Did you replace the cluster? Did the mileage read from the computer or did it read what the new cluster said? If you needed to get it programmed, how did you go about doing that?

    Hi, I bought a rebuilt cluster at Advanced Auto Electronics ((804-427-1111) It cost $175 (you send back the old one). It was perfect - they are really nice people. My mechanic installed in in no time. The cluster picks up the cars real mileage from the computer. It's almost a year since I got it and still working perfectly. Good luck.

    Oh forgot to mention - no programming is necessary. Only need programming if you change the car computer. You are only changing the cluster and as I mentioned it automatically pics up mileage from computer.
  • The odometer on my 97 Sunfire GT stopped working. How do they work are the mechanical or electrical? What would be involved in testing or finding out what is wrong. This car is new to me

    Thanks for responding

  • The first and second stages do not work on the the fan, stage three and four work fine. How can I fix this problem.
  • I have a 1996 Ponitac Sunfire that I just bought under a month ago. Dealer sold it to me cheap because of the electric work that needs done. Turns out the damage was more extensive then I thought, but the engine runs great. Just drove it out to Kansas City from Indiana with no trouble at all. Until after I got here, that is. Tried starting it to go to work, and it turned over, revved up, then died. Got it to start up, shut it off, then came back about a minute later, and it wouldn't start. Same problem.

    Electric issues include: Every dash light coming on and staying on when driving. Very dim driver side headlight. Radio removed by dealer to help with elcetric issues. Ignition switch replaced about two weeks ago.

    This is the first time the engine has given me trouble. Any help would be very much appreciated
  • If only two stages on the fan work but the other two don't work, then you'll have to replace your blower motor regulator.
  • My 2005 Pontiac Sunfire has had several problems over the past couple of months.
    When I was driving all my gages went to zero when I would start to break. After I started moving again they would go up. Also my lights started to dim. When I had the air on all my gages went to zero; when I turned the air off the gages went back up, when I had the lights on. The theft system and service light was on. The mechanic put three different computers in the car. Put in a recall part. Also put in a new part were all wiring connects. They fixed a short near the gages. They did more stuff that I am not sure of. I know they worked on the ground wire. After he told me he could not fix it. I put a new battery in it. Then it worked for a couple of days. I am getting a new belt in tensor put in on Wednesday since that has been something that has needed to be replaced. Now it works most of the time. But the lights still dim. But the theft system lights come on and service so it locks up cruise control. But now the gages do not go to zero. My dad says I do not need new head lamps. But my turn single lights do need to be replaced. Every test that has been run on my car shows that everything is fine. What else can I do?

    I apologize for the problems you are experiencing with your vehicle. Are you working with a GM dealership or an independent shop?

    Thank you,
    Caron, GM Customer Service
  • I am working with independent shop. Who has called GM several times. Also called GM Dealerships. He has most of the problems fixed now. Since the first people he had worked on were wrong. He found things wrong were they did not look. I will still buy GM made vehicles. I still love the car.

  • Hi. I recently had an oil change & a new battery put on @ wal mart on my 2004 sunfire. As soon as I left I noticed all my warning lights on, check engine, brakes, anti theft. I was still in the wal mart parking lot so I took it right back around & told them something was wrong. They did something under the hood, I don't know what. I was in a hurry to make a 4.5 hour drive to see my granddaughter be born. So I started driving home & noticedall my gauges fluctuating like crazy! The car was driving fine though so I went ahead with my trip. There were times it said I was going zero & it said my full tank was empty. So I get home & I call a friend from high school who is a mechanic & he tells me to check my battery connections & the fluid in my battery. I told him it was a brand new no maintenance battery. He said check it anyway. So I check & notice the negative connector is not on very well & I'll be, my battery was only half, if that full of acid. I take it back to wal mart & encounter the rudest person alive, also the one who originally put my battery in. I told him what the problem was & he fixed the connection & then went & got water from the drinking fountain & put in my battery. I called my dad & told him & he said take it back & make them give you a new battery. He should have never put water in that one & it won't last as long as it's supposed to. So the next morning I went back & they were appalled by what he had done, said he should have automatically given me a new battery. So they decided the one he put in was the wrong size, not enough amps & gave me the right size battery. I thought ok, that was my problem. No. So I went back today & met jackass #2. He said it was probably my altanator, which he checked & it wasn't. I told him I thought when the first guy hooked up my battery the first time he did it backwards & messed up my computer system. He said if my computer system was messed up my car wouldn't start. Maybe I should have said electrical system. My town is small & there are only private mechanics. I'm supposed to go sometime tomorrow for a diagnostic check. It's just that I didn't have one single problem other than needing a new battery before they put in a battery & 2 new terminals. I've checked all my fuses. My problem is I have brain cancer, I'm on disability & now I have to go pay for a diagnostic? Of course if it comes back battery related wal mart will reimburse, they say, but I have a feeling it's going to be a fight. Has anyone else had this experience after getting a new battery put in?
  • Hi, I have a problem on my 2000 Sunfire 2.2. First, i change the steering column because the other ingition key broken and i can get out of OFF. So the less expensive was to by a other complete steering column at a scrap yard. I change it but the car does'nt want to run. The Starter run and the engine crank up but nothing. I ive chek my fuse my fuel pump relais and every thing is fine. By the way my air bag light and car lock is on so....

    If anyone have an idea what is it ?
  • sounds like you messed with the anti theft program

    Ok, after fighting with wal mart and taking down names & dates "my log", I finally go back yesterday bound & determined for them to pay to get my car checked. I'm not unreasonable, I take responsibility for my vehicle. However, I know everything worked fine, they put in a new battery & it then it didn't. I also didn't like being talked down to like I was dumb. "Oh, if your battery was hooked up backwards to begin with & fried your electrical system, your car wouldn't even.start". This is not true! So I went in & asked to speak to the manager & here comes the guy who initially put the battery on! Also the same guy who put drinking fountain water in my brand new battery. I said, no way. I don't want to talk to him, please get me the store manager. So it was the same lady who was there when I got my second battery. I think they are just tired of me because she said, we are going to fix your car. Take it to a certified GM mechanic for an estimate & if it's over $250 we have to get coperate to approve it. I asked her how long that takes & she said, it depends on your adjuster. Well, they won't fart around about because I'll call everyday. So, it turns out there is a certified GM mechanic only about 22 miles away. I take the car there & explain everything. He tells me he still has to run some diagnostics on it & they cost 95.99. I almost start crying. Then he said, if I go ahead & sign for them to do the repairs & not take the car with me, but leave it there, they will just add it to my final bill. Which I did. Diagnostic & driving tests led him to believe that improper installation of the battery fried my electrical panel. So, scott from wal mart, I'm not so dumb after all!
  • usually in the steering wheel
  • I have a 2000 pontiac sunfire and it's obviously giving me problems. first and most threatening is the fact that it stopped shifting. Around 20 mph it revs at around 1800 rpm and 30 at 2500 rpm. it started after hitting a pot hole in my works parking lot. i took it to a shop and they replaced a fuse and it was good again. hit another pot hole going down a hill and it went out again. took it in again and they said it was a wiring problem, fixed again.. they i didn't hit a pot hole but a little ditch thing in the road that i go over everyday after work, it locked up and i had to pull over and turn the car off. turned it right back on and everything was fine but wouldn't shift again. took it in again and they said transmission. but there's to many electrical problems that persist to just ignore. left head light keeps going out, my right blinker light keeps going out, when i put my car in drive my head lights and dashboard lights flash fast about 4-5 times, then service light comes on. i was told to check my ground wire but im not sure where that is. checked the battery for corrosion and none. fuses look like they might be all burnt but yet the lights and such still work, so i'm not to entirely sure. i was also told to check all wires to make sure they are sending the electrical current where it needs to be. another told me that i should do a transmission flush. if that didn't work then change 4 of my (not sure what they are called, i presumed cylinoids but i know that's not it, it's in the engine though). i would like to just check every wire before spending any money cause it seems like the electrical problem might be the cause and nonetheless still a problem. any information on this would be greatly appreciated.

    Hi, Im having the exact same problem w/ my 98 Sunfire. Im glad you were able to prove that Walmart was at fault afterall. However, I purchased my Sunfire used w/ this same issue already in place. It acts up intermittently and didnt act up until I had the car for a couple days. I purchased it from a private owner and have no recourse.
    Was the dealer able to determine what was wrong or causing the problem. If so, what was the issue and did it resolve the problem? I was told I need to replace the instrument (dash) cluster. However before I start changing random things, Id like to see what resolved your issue first. Thank you for your time.
