    Thread: Fuel Gauge and tachometer not working

    1. 04-04-2007 05:48 PM #1
      I am trying to fix these 2 gauges on a 1990 cabriolet along with the power windows.

      The gauges are on the off position and do not move at all. I found a nice writeup on the power windows so I should be fine on that aspect. Every other component works and all other gauges and warning lights work also.

      I thought I should ask where to concentrate on, the grounds or test the back of the cluster or somewher else maybe someone has had a similar issue, thanks and sorry for the long post.

      How to Fix the dash in the cabby…

      My tach, fuel gauge, temp gauge and all the idiot lights/turn signal lights went out in the cluster. occasionally, hitting a bump would send them working again, before they'd crap out again. son of an electrical engineer that I am, I discovered that I could get this set working again by reaching up under the dash and wiggling the main plug that attached to the cluster. But this didn't always work, and I eventually forgot to reset my odometer and ran out of gas - because the gauge happened to be out.

      My trusted VW mechanic told me his experience with this common issue and gave me the fix, which I performed myself. The problem lies with the flimsy/worn contacts on the cluster's main plug. (the "male" side) You will notice that the contacts simply wrap over the plastic male end of the plug. The fix is to pull back the contacts and wrap a bit of electrical tape over the plastic. When you rewrap the contacts back over the tape, you will now notice that you'll get a tighter fit when you plug the male end into the female side. Of course, spray it all with contact cleaner before you reattach it all and hopefully auto's cured.

      Been there and done that. That connector was a particularly brainless design.
