Hey all,
New YJ owner… 88 Sahara with 7800 miles… all original and uncut.
I have been going through all systems as I bought this Jeep last month from a collector who had it sitting in his garage for a few years. One issue has me going crazy…
On the 88, wiper stock is on the left of the column, and you toggle a thumb rotator forward for washer fluid and temporary wipers. Backward washes rear hardtop, which this rig does not have.
When I topped off the fluid, tested the washer and nothing happened. Also, wipers didn’t come on temporarily. The wipers still work when switched on from the stock. I confirmed with an air compressor that the line is clear to both sprayers, confirmed all fuses under the dash near the parking brake are good, I see no loose wires. I also pulled the OEM washer pump and installed a new one from Quadratec. Still nothing.
I got the volt meter out and when the washer pump was disconnected, I probed the wiring harness plug and it came back at 8+volts, and the wipers actuated… I also reversed the poles on the motor thinking someone may have been in there before but nothing… so I know the fuse in the circuit is good, the stock switch works, wiper motor works, electric at the terminal, but can’t get the pump to work…
Lastly, not sure if related, there’s an unknown female plug hanging loose just outside of the terminal block under the hood… I don’t think it’s related, but not 100%.
I have also checked the wires for mice or splices and everything looks factory new…
Any thoughts on this one? Help is appreciated.
