Having problems with your 1994 BMW 3 Series ?
The gauges on my dash periodically stop working then at some point will reactivate. When they stop working my wipers mess up and I have no climate control. When they reactivate they act as if you have just turned the key on.
Most likely you have circuit board issue within the instrument cluster. Its very common for them to have problems. Thats why there are places that rebuild them. modulemaster.com is one of them. You could remove the unit and inspect for bad connection or do a wiggle test to see if that helps. Or tapping on the dash or unit might indicate something. Other than that you would need test equipment and wiring diagrams and a couple hours at least to try to diagnose this. Wiring diagrams you can get on alldata.com you can even get the troubletree that you would follow to address this.
