Bruce Everett: ok sounds like you got a bad speedometer head.. we had this problem happen
to us.. so we replaced it and that fixed it.. you can sometimes find a used
one at a salvage yard in which case we did that .. was cheaper than having
to buy a new speedometer cluster set
steven baker: This would be the body control module.... sir
Tony Flick: Mine didnt have the same issue.. but i tryed fixing the bulbs myself to
leds and totally messed it up.. the best thing to do is just go to a junk
yard and get 1 from 10 to 30 bucks... better then paying 300 for a new 1..
04holmes1: I mean did not post this @04holmes1
Mathieu Caron: same here
avcomext: HI I HAVE A SUNFIRE 99 WITH THE SAME PROBLEM SINCE 2 YEARS. DID YOU GET A
SOLUTION THAT YOU CAN SHARE TO ME?
Scott Kearley: Its Diffenitly an Electrical Problem I Had A 99 Cavalier That Ad A Diode
Gone In The RPM Gauge And All The Other Gauges Got A Malfunction In There
Lead Power Source The Car Got Confused Sometimes The Other Gauges Would Go
Out .. I Took The Car To A AC Delco Mechanic He Said That One Gauge Can
Make Your Other Items On The Instrument panel Go Wacky Because They Think
That The Car Is In ACC mode Even Though Your Car Was Powered On The Gauges
Think Your Shutting The car Off And On Before It Reponds
Scott Kearley: that only works if you have lead problems or contact not electrical....and
if your car had no ground it wouldn't work..... i got a 03 Pontiac Grand
Prix In My Backyard And The Grounding Unit Fell Off Somewhere Because The
Car Is A freaking Piece Of crap And Rusty In Order To Get The Car To Start
Or Do Anything I Have To Get A Ground Manifold
nicknaggriff: did you ever figure this out? my 03 cavalier is doing the same exact thing!
norm: All my lights are on. Just started today I did my blogs change my oil. And
that's what I get for doing that I don't get it. Men don't know how to fix
it. I'm a little agitated. My car doesn't have to be on for the lights to
come on. Strange does anyone have any ideas
04holmes1: Sorry I did boot post this earlier, but to solve the problem I replaced the
body control module (bcm). I got a new one cheap on Amazon and had the
dealership flash the code for my key fob. In total it was a 10 min
replacement and about $125.
Frank Guerra: i had a prblem with my 2002 and it was a bad cell in the battery and ruiend
my alternator also
Jose Barrera: i just fixed my 03 cavalier it was doing the same thing i solve it by
runing a wire from the negative pole on the battery to a bolt on the
firewall also make sure the ground on your negative cable is bolted to the
battery tray... this problem is caused due to bad ground....
2012GreenGhost420: HAHA Welcome to owning a 2001 Cavalier!! Mine does this crap too
