    If you go here

    and follow the directions, you can see the titles of all the recall bulletins for your 2004 Cavalier. If you find a bulletin of interest, you may be able to access the complete bulletin through ALLDATA at your local library.

    Taking a quick look, I did not find your problem listed among the bulletin titles.

    My '02 Cavalier 2.2 liter, 5-speed with 108K miles failed our stupid emissions check testing yesterday. It needed an evaporator component, which I promptly had fixed, but also it failed because the Check Engine Light (MIL) doesn't come all. OK, a burned out bulb? Dealer says you can't replace the bulb, but must replace the entire cluster..speedo, odo, fuel and temp gauges, tach, all warning lights...just because ONLY the check engine light does not illuminate. Cost? $410.00!

    Is this for real? I'm angry at our stupid state (Ohio) for having this law...I mean, this repair will force me to choose between brakes (what it needs) and getting this stupid light fixed, even if my car is not polluting...and also GM, for making a design so stupid.

    Is the dealer telling me the truth, that the bulb can't be replaced?

    I would say it is replaceable, people have replaced radio lights. The problem is how hard is it to get to and would Radio Shack or such have one to fit. They are usually soldered in and why the dealer won't do it. They do like to sell parts. Ask at an independent shop and see what they say about it.
  • Ignition switch sticks while trying to turn engine on. Steering wheel locks and wigglingit does help but it should be more fluid. Any help out there?
  • that is a 2003 cavalier and it does stick as if there is a pin dropping into place or it is catching on something.

    I just bought a 2003 Cavalier Coupe and everything works great but sometimes when the car is turned off, the guages on the dash don't totally reset and go all the way down. The temp and fuel guage in particular. Therefore when I start the car, the fuel guage for example (when the tank is full) goes shooting up from where it got stuck sometimes all the way over to the temp guage area. I know the previous owners just put in a new battery, so could I be experiencing the same issues as the origional poster? Thanks.
  • Hello all. I have a 2003 Chevy Cavalier 2.2 Ecotec. I just put in a new air intake system, but I am looking to run a new cold air tubing in place of the stock mounted one, which I removed. The problem is, the stock battery is in the way of the new air tubing, so I am wondering if anyone knows if there is a smaller battery available to put in place of the stock, with the same cranking amperage.

    My current battery measures as follows:

    L = 9"
    W = 6.75"
    H = 7.25"

    If anyone can help me out, I would greatly appreciate it!

    My daughter had an after market radio/cd player installed in her 04 cavalier. I was told that the lights left on alarm would not work with the new radio. I figured no problem, I had installed the alarms on other vehicles using the fuse box. Long story short, I tried different after market alarms and chimes (including Radio Shack), but can not figure out the correct fuses to connect the wires to. I have tried all combination outlined on the instruction, plus many others, but the alarm still does not work. Oh by the way she has had to have 3 jumps already. Would appreciate any help.

    I have 2004 ecotec which has the same reset problems. My dad is a mechanic and we think there is a board inside the dash thats has become warped from heat. We haven't taken it apart to check yet but we are planning to. Any helpful hints would be much appreciated. I will share any info i happen upon.

    I just tried to install a headlight on chime in my girlfriends 03 Cavalier. I had the same problem. She also has an aftermarket radio, but I don't think her car came with a headlight on alarm, stock. She's had on battery replaced, and several jump starts too.
    We have a stupid law in our state that requires headlights to be on when the wipers are being used. A real boon for the tow truck companies! If I can solve this, I'll pass along the solution. Have you heard anything else?

    I just pulled a 2.2 out of my 96 coupe. I disconnected 29 of the 30 connectors I was supposed to. I now have a white and an orange pair of wires dangling off the harness. The connector is a 6 pin in the coil pack. The pin designations are A, B, C, D, E, F. The wires were in D & E. I need to figure out which goes where though. I've called dealers, looked in junk yards. I have not found one yet.
  • I found a web site today called On the right side of the home page it has a research section. I clicked on the Technical Services Bulletins & Recalls link (it's blue). On the bottom of the page it has Step One, Step Two, and Step Three. Just fill in your auto's info & follow the directions, I finally found out why I don't have any back-up lights. The car was recalled in Jan. of 05 and I bought the car in May of 05. Never knew. Now I am in the process of finding out if I can still get it fixed by the recall. There are alot of different things there and it doesn't cost a thing. Maybe it will answer some of your questions as well.
    Good Luck. I hope it helps someone.

    I wonder how you managed to get detailed Tech Service Bulletin info from without paying the $26.95 for a one year subscription?

    You can go to most public libraries and get this info for free, but not from your home computer.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,570
    They have a one-time fee as well, don't they? I mean, a single-use fee? I think so.

  • The web site lists their least expensive subscription as being for one year for $26.95, no one time fee that I can find.

    And I have not found their data to be quite as good as complete Service Manuals (but I know how exorbitantly overpriced those are!)
  • I should have mentioned that, although you can't get the detailed Recall and Tech Service Bulletins for free from , that web site is still a very convenient place to find if there is a recall or tech bulletin available for a specific vehicle and year, regarding an issue you are interested in. Then you can go to your public library knowing the exact TSB number covering that issue.
  • Mr_ShiftrightMr_Shiftright Sonoma, CaliforniaPosts: 57,570
    Yep you're right. I must have dreamt that one-day subscription. Not a bad idea, though. They should do that.

  • Hello, had the same problem on my 97 Cav. Take out the drivers side headlight. Untape the harness behind it. Pull out the the wires. The pink wires are for DRL . There should be a connection of 3 pink wires. Chances are this is corroded and will need to be resoldered. hope this helps. Jim
  • My daughter has a 93 Cavalier, a few months ago it would not start found that the ignition had come loose, so we tighted it back up but every now and then the A/C-Heater fan stopps working and when it isn't working the Radiator fan is not working as well, along with the ABS light being on. Could this be the ignition switch needs replaced?
  • On my 2000 Chevrolet Cavalier: I lost the following gauges at the same time: temperature, fuel, speedometer.
    Any suggestions? Thanks, John Miller

    You might have your repair shop perform a Diagnostic Systems Check on the Body Control Module using their scan tool, to see if any trouble codes in that system show up. You have to start somewhere and the BCM does control the instrument displays.

  • I have a 2005 chev. cavalier.My cooling fan is not coming on. But, the fan will come on if I turn my ac or heater on. I have replaced the engine temp. coolant sensor.I have also replaced the air temp. sensor. I have also replaced the thermostat. Plus I have replaced the cooling fan relay. But, my cooling fan still won't come on. I have checked my wiring out under the hood. I noticed that the air temp. sensor and the engine temp. coolant sensor and the thermostats wiring all connect to the igination control module. I wanted to know could this be where my problem is coming from.
    Could anyone please tell me what I need to do.Puls my temp. gauge is acting wacky.
