This is my first post so first of all Hello!
I have a question about my wifes temp gauge on her Cavalier. When she was driving it today the temp gauge fell over past the HOT mark (she has a quarter cirlce temp gauge right next to the speedometer, the temp gauge is on the right side) and is now sitting on 10 MPH mark on the speedometer. When going over 10 MPH the speedometer hits the temp mark and doesn't go any farther. I know the car is not overheating, it has plenty of coolant. When turning the enginge off the temp gauge moves back some. Any idea what causes this and how hard is it to fix? Do i need to replace the whole instrument cluster?
Thanks
