Hi Vanessa; It appears that your problem is a very common complaint with MANY Cavalier and Sunfire models (2001-2005).
Many remedies or solutions include doing the following:
- Check for a bad ground connection
Replace the strap(s)
- check the existing ground strap for any oxidation (green stuff)
- partially broken or fully broken ground strap
- ground strap from the battery to engine block
- ground strap from the engine block to the frame or firewall
- Check the cluster gauges for poor or missing solder connections; or some that may have loosened.
Re-solder the connections or replace the instrument cluster with either a new, rebuilt, or used instrument cluster from either the OEM, third party vendor, or junk yard.
- Check the fuse panel for blown fuses; service manual notes (depending upon style model) that there are either 1 or 2 fuses that controls the instrument gauge cluster; (maybe marked CLUSTER or CLS/PCM; or BCMCL).
- In the event the fuse(s) are not blown:
- Disconnect the battery ground cable from the battery
- Remove the fuse(s); turn ignition key cylinder to AUX position (not "start" or "run" positions), wait about 30 seconds, to fully discharge remaining capacitor voltage to any of the car's electronic control modules.
- Reconnect the ground cable to the battery
- and re-insert the fuses that were removed
Hopefully this will resolve the problem. Unfortunatley, I have read where some car owners have replaced their instrument gauge clusters 3 times; which leads me to believe one of two things; either there is a serious defect in the manufacture of these instruments (but I have not seen any mandatory or voluntary recall by NHTSA or GM) or because of some sort of owner related fault...like improper battery jumping procedures- causing a voltage spike, etc.
Hope this helps.
