Having problems with your 1988 Pontiac Firebird ?
My speedometer is not working and the security light comes on sometime and the car wont start
On my '98 Blazer I found that I had this as well as the interior lights not working. I was able to find a 10amp fuse in the underhood fusebox had blown, it was labeled something like Chasis/body. I replaced it and every thing went back to normal, except the Speedo/odometers.
