Having problems with your 2004 Chevrolet TrailBlazer ?
Temp hand is sticking, it is saying it is hot and its not.
When you start it up after 8hrs. it still says 210F.
The stepper motor (servo) which drives the temp gauge has failed and needs to be replaced. There are services that repair instrument clusters, look on Ebay.
