I got a problem with 96 Grand Cherokee. When Ign is turned on before start the blue high beam light comes on. But after engine is running when the high beams are on the blue light doesn't come on. Also on the wiper delay it does not function correctly. On delay when wipers stop they stop in the up posistion. Put in a brand new switch from dealer and still the same problem. Help with any known on going problems or is this an isolated malfunction. <img src="/forums/images/graemlins/confused.gif" alt="" />

It sounds like you have two different problems.

The "park" feature of the window wipers is a function of a limit switch inside or attached to the wiper motor. If the wiper switch is turned off in mid-stroke, the limit switch will keep power on the motor until the blades reach the park position. However, if you turn off the ignition key while the wipers are running, all accessory power is removed, and the blades will stop where they were when the ignition switch was turned off.

I can't see how a problem in that area would affect your high beam light. It's possible, I suppose, but I can't figure out how.
