calibermoon: 3 weeks ago I bought a 2005 Chevy Cavalier. It looks great, low mileage, everything works. Sporty, fast, and great MPG, Its was a win win for the price.
2 weeks ago, the speedometer started displaying incorrectly. I would be driving 35 mph, but the speedometer was displaying 110 mph. My GPS tells me how fast I'm traveling, so it wasn't a huge concern at that time.
Last week, I took it to my mechanic to have it repaired. He replaced the speedometer sender with no luck. He said that my instrument cluster was bad, He said it would be over $400+ to correctly repair. I was thinking, "I guess my GPS is going to be my speedometer for awhile".
After a few days, it was driving me crazy. The speedometer limit is 120 mph, but now the peg is pointing straight down like I'm doing 150 mph. At any speed:(
I've done some research, and it looks like GM had major problems with instrument clusters from 1999-2006. The problem is enough that many people are calling for a recall. GM's current position is that its the owners responsibility to fix this.
Google 'GM Instrument Cluster'.
I found I place that will fix this cheap, but I would not be able to use my car for a few weeks. I would have to remove the cluster myself, ship it to Utah. Wait for the fix, and have it shipped back.
I still love my car, and intend to keep it. But there must be a cheaper solution.

MK3 Jetta: Here's the 3 steps to do: 1. Pay the neighborhood daredevil to siphon that full tank. 2. Sell the cavalier for scrap. 3. Buy a MK3 VW Jetta
Jeff S: Definitely a bad ground. I tried every other thing on my mother's 2001 Cavalier. Nothing fixed it. Then I attached a grounding strap from the engine block to the firewall. That cured all the problems. Make sure your battery-to-engine block ground is clean and tight. Sand down to bare metal on the firewall if you attach a grounding strap or wire. The problems began after getting a new heater core. There must be a ground wire somewhere in or on the heater core box that got broken or was never re-attached. Also, the radio is keyed to the BCM. I had to re-install the original BCM to get the radio back.
Alicia Tulcus: Have your automobile engine code checked. If it says no communication with the body control module. There is some ground connection around the battery. That is were I found it. And check your voltage and ground ecm and boc you will usually find a bad ground..
Mathieu Caron: same here
2012GreenGhost420: HAHA Welcome to owning a 2001 Cavalier!! Mine does this crap too
04holmes1: I mean did not post this @04holmes1
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.
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
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
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?
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..
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....
nicknaggriff: did you ever figure this out? my 03 cavalier is doing the same exact thing!
Hair Do: Thanks for the tip. I do know it's hard to earn money. But it is much better than working minimum wage at mcdonolds. Being an hair stylist does get tips and I end up making decent money. Plus it allows me to be creative sometimes and make customer's dream come to reality.
