You mentioned relays and wires, but did you check fuses?
Fuses or grounds or the wires could still be bad. You have to measure the voltages dropped across them. Good luck.
Probably
The motor may have quit working .
If it has a power distribution panel under the hood--check fuses and relays in there
They're probably frozen to the windscreen.
I found that my wipers stopped working after I tried to turn them on after a ice condition. The answer was that the wipers are omounted to a tapered fitting and all it needed was to tighted the nut outside at the base of the wiper arm. HOPE THIS HELPS........
The wipers of a Subaru Legacy will stop working if the fuse has blown or the motor is defective. The wiring harness may also become corroded or loose.
fuse
Fuse? Connections? Switch? Wiper Motor? Could be any of those.
First the issue with the wipers and blinkers is a bad fuse. The issue with the car not going into drive is the shift censor needs replaced.
its the motor.
Blown fuse, broken wire, failed switch,
The number eight fuse is the fuse that controls the windshield wipers. The number eight fuse can be found in the first column, second from the bottom.
