1993 Jetta - both the tach and speedo, clock and mileage indicator
suddenly stopped working. However the fuel and temperture indicators
are OK. I've given the dash the old Fonzi love tap but nothing. Maybe a
rubber hammer is required! My mechanic checked that the grounding is OK
within the engine comportment. What do I do? Take apart the dash and
check the instrument cluster? How do I do that exactly?
