I have a 2002 express van LT (Factory Conversion). It had the transmission "shell" break and sometime after it was repaired I found that the back up lights don't work. The vehicle is now out of warranty (45K) & the Dealer won't check it without my paying. Bulbs and fuse are OK. Does anyone know where the back-up light switch is located? :banghead: The service manual is no help except to show that there is such a switch.
