It is possible it is the body control module, I had the same problem except my brake lights worked.
You need gauges to properly charge it.
That is the part with the gauges.
check fuse in fusebox on left lower dash . It is fuse nomber 15 ,10 amp fuse . Could be the problem.
they dont work
In the fuse box under dash, left of steering column.
It defiantly can be relevant. Moisture may have damaged the gauges or the wiring. Have the leak fixed before repairing the gauges. Have you checked the fuses and all connections.
i had the exact same problem with our 91 voyager, i cleaned the battery terminals and the problem went away immediately
The problem your having doesn't sound like a fuse.it could be as simple as the grounding wire from the frame to motor or body. there is a ground that connects to one of the bolts on the windshield wiper motor. I'd start looking there first
It could, along with the gauges themself and dozens of other causes. A scan tool capable of communication with the body computer and cluster is required to diagnose.
It means that you have a low reading on one of the gauges and you need to address the problem.
I had a problem with that every once in a while. It seems like its nothing to worry about. But at the same time, keep your eyes opened. Mine hasn't done it in over a year either.
Happened to me while driving. Jumpstarts and waits only worked for a few miles. Was able to get to Sears and resolved problem with new battery. Also had them check the alternator.
