Electrical problems with 98 Plymouth Grand Voyager dashboard goes out like the engine has been turned off delay wipers work when they want etc but the engine continues to run normal?
Sounds like a bad/loose fusable link. That's the "fuse" in
between the battery and the fuse box. It's on the wire in between
them. Check, clean and tighten all battery cables and wires
connected to battery. See if that helps.
