Have you scanned the system to see if there are any fault codes setting?

Customer: replied 8 months ago.
No sir I have not
Expert:  Ron replied 8 months ago.

Okay doing so would be a good idea to help determine whats going on here. That being said the tachometer gets its signal from the crankshaft position sensor located in the block behind the compressor and its common for them to fail but you will usually get a code indicating a failing Crankshaft position sensor.

Okay thank you sir l will go get one now. Can I come back to this page later and ask you something if I have a question?
Expert:  Ron replied 8 months ago.

With out checking for fault codes its a bit of a gamble but for the price of a new one its sure a good chance that will solve the problem as well. See the location and removal steps in the link below as well. Have a look and let me know if you have more questions and or need more help .
