The problem with a problem you are having is that it takes a great deal of time to troubleshoot and is not worth the amount of labor required. You wouldnâ??t pay $300 or $400 to get it fixed and your mechanics not going to spend all day with it for the $80 thatâ??s its worth. The â??itâ??s the wiring harness bring it to the dealerâ? is just the mechanics way of saying he doesnâ??t want to deal with it.
Do you have any other symptoms when it happens like dim panel lights or the fan slowing down?
