QuestionMy Tach in the gage cluster stopped working, speedo still works. Could you direct me as to what to look for. I checked fuses but they appear ok. Thanks.
AnswerHi Jimmy Joe,
It could either be a problem internal to the cluster itself, or there could be a problem with the digital data bus not sending a signal to the cluster for the rpm. Start with the cluster by doing a self-diagnostic test.
With the engine OFF press the trip and reset buttons.
Then while holding the buttons turn the ignition switch to the ON position
Continue to hold the buttons until the word
CODE appears in the odometer window, then release the buttons. If a problem exists a trouble code will appear, or in no problems then a 999 will appear. When chec-0 appears the lights should dim slightly in the cluster, if not then there is a problem in the cluster.
When chec-1 appears the gauge pointers will start to move. The tach should show 0, 1,000, 3,000, and 6,000. Chec-2 tests the odometer segments, and Chec-3 tests the transmission position indicators. Let me know how the tachometer behaves (no pointer movement or irratic pointer movement, or proper pointer movement). Then write back and tell me any codes that appeared.
