One problem related to instrument panel has been reported for the 2000 Chevrolet Blazer. The most recently reported issues are listed below.
I have a 2000 Blazer and I have been having problems with the fuel gauge for the last 6 months. It fluctuates between full & empty constantly. Once it hits a half tank, it stops keeping track of how much gas is in the tank. Haven't had it fixed yet. Seen too many complaints now, gm should replace for free.
