I have a 2002 VW Eurovan (very big lemon, FYI). I just picked it up from the body shop, and noticed that the mileage LCD and the Transmission LCD (1 2 D N R P) and the clock LCD are all partially blank. I can see some parts of numbers in the mileage and the colon on the clock. When I picked it up from the body shop the guy had to use one of those insta-jumper deals to start it because the battery was dead. Could that jumper have killed my LCD displays? If not, what could be the problem? Thanks. ---

Not if he used the jump pack properly. All bets are off if polarity was reversed,even for a brief monent. One value that I would like to know is just how much voltage was introcuded into the cars electrical system. I would think a jump pack is safer than an AC unit. I have seen AC units output 15.5v,and this would concern me. ---

I can’t say anything about the polarity. So maybe it wasn’t the jump pack. Any other ideas as to what could cause this on three separate LCD displays? What is the fix? ---

Does anyone have any idea how this problem can be fixed? Thanks. ---

There could just be some burned out bulbs. Get a manual and learn how to get to these offending items to check.
