    Default Periodic speedometer and tachometer not working

    Hi,
    I recently purchased a 1999 Cherokee 2,5 diesel.

    From time to time the speedometer and tachometer "drops dead" also the Airbag warning light comes on. This happens while I'm driving. After a minute or so it usually starts working again and the airbag light goes out again.

    I suspect some kind of wiring with bad contact. Anyone got suggestions to where I should start looking ? Known problem perhaps ?

    regards

    Two things, first remove the instrument cluster and clean the contacts for the connector behind it, and second if that doesn't work, I want to say the clock spring may need replacement

    More often times than not, when you start having instrument cluster issues, and the airbag light is on..... the culprit is the clock spring.



    Here's a video tutorial on how to replace it... it's pretty easy:
