Warning Lights on 2002 Cavalier 2.2 auto trans
« on: March 16, 2009, 07:35:49 AM »
Hi all, I'm new here and a complete idiot when it comes to cars so please bear with me!  :)

So a bunch of the warning lights in my car all came on at one.   One says "Service" with a picture of a wrench, "Trac Off", "ABS", and Check Engine.    A little playing around has revealed that my ABS seems to be not working at all.   

Also, possibly related or not, I've noticed the car seems "underpowered" electrically.    My lights or fan will dim randomly, not just when it's been idling for a long time but even if I'm just cruising down the highway.   The last car I had that happen to it turned out to be the alternator, which I suppose if there's massive electrical problems it could be screwing with sensors and whatnot. . . . or not. . . lol. .

Anyway, ppreciate any help I get on this.   I plan on taking it to a shop anyway but don't want to get ripped off.

Doc, if your charging system and/or battery are malfunctioning, it could make all those lights come on.  The vehicle will disable those systems to conserve electrical energy to help you get it to safety.  Get it serviced asap so it doesn't leave anyone stranded in a potentially dangerous situation.

One simple poor ground problem can cause all that grief, with some loads on, place a voltmeter directly on the negative battery terminal and to the block and to a frame ground for next to zero volts.  A very common problem is corroded battery terminals, how old is your battery?  You wanted something simple, can be this simple, next to more complicated would be the ignition switch, but your head lamps are independent of that so suspect you either have a bad ground or dirty battery terminals.  Warning lamps will go crazy with a poor electrical connection.
