My 92 jeep wranglers windshield wipers stopped working

faulty switch. I would replace that first thing.

when they do not work turn the key to the run position, the vehicle does not need to be running, and the wipers set to high speed whack the wiper motor with the handle end of a large screwdriver. if the motor starts to work replace it.

I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_d728a59f986299fa

under the cowling on the front of the jeep where the windshield meets the body.

How do I get to the windshield wiper motor on a 1990 Jeep Wrangler?

TAKE IT BACK THEY HAVE LEFT A LINK OR POWER FEED LOOSE

Hi there
I read your report. The fuse is 20amp. Ty for writing to fix ya.

It sound like something is jammed, or slippeed out of place. Remove the section the is between your hood and windshield (where the wipers stick out) and have a look at what is going on.

2008 should be under warranty, take it back to dealer.

With all of the electronics on vehicles today, seems like these sort of system failures are becoming commonplace.

Under the left of the dash board close to the parking brake tucked up under.

I had a similar problem with my 2000 Jeep TJ and I found the problem in the wiring harness under the hood.several wires were corroded and almost burnt off.If you remove the black tape which keeps the harness bundled together and if you see evidence of "green" type powder or "gook" it's most likely where the wires have faulted.
