Help with my instrument cluster
Hello everyone, I have a 1994 C200 D, and during the first few days of driving it, I noticed that the fuel gauge was acting up. Sometimes it worked, sometimes it didn’t, and if I tapped the dashboard a few times, it would “come back to life.”
About a week ago, my speedometer needle jumped out of place after I hit the dashboard trying to get the fuel gauge working again, which forced me to remove the instrument cluster. While I had it apart, I cleaned the whole cluster inside with isopropyl alcohol and moved the temperature, fuel, speedometer, and RPM needles.
After reinstalling it, all the gauges were completely out of calibration: with the engine cold, the temperature gauge was already showing close to 80°C, the fuel gauge became completely inoperative, the speedometer was reading incorrectly, and the RPMs were showing higher than they should.
After opening it again, I managed to get the speedometer and RPM gauge working almost correctly, but I still have no idea how much fuel is in the car, and the temperature gauge is always stuck near 80°C.
What can I do to fix my instrument cluster?
