Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is***** sounds like your instrument cluster/gauge assembly is failing. If it was anything else such as a speed sensor check engine light would be on and vehicle wouldn't shift correctly. Also the complete cluster is powered off one fuse so if it was a fuse problem then nothing would work. You can try to disconnect battery for 10 minutes to reset system but if that doesn't help cluster will need to be replaced which is about a $500 job at shop. Let me know if you have more questions, thanks.
