Rear wiper running non-stop

[Awagner]

I got my explorer last august, and within the first mont of having it the rear wiper would run non-stop usually in the mornings... after the sun came out the thing would work normally. I suspect that there is a wire or connection getting wet causing it to malfunction.

I ended up pulling the fuse and ignoring it, but i would be nice to clear the snow off it by pushing the button instead of replacing the fuse.

has anybody had this trouble before??

if so how to fix??

Thanks

I would check the relay first, then check the switch.

Sounds like water has leaked in and made the connection. Have a look around the wires to see for water.

Hope this helps.

i had the same ####ing problem, my god it was pissing me off. one day i pulled over, ran to the back, and ripped the whipper off of the base. currently its still sitting in the back of my X. the thing that really pissed me off was that it wasnt constant. sometimes it would stay on contiouslly, sometimes it wouldnt. guess it was the explorer getting back at me for not treating her right

I have the opposite problem in which my wiper doesn't work at all.

Relay

I would look into replacing the relay for the wiper. When my fuel pump relay went bad it would give power to the pump when it was unwanted. Relays are pretty cheap and easy to replace.

I believe your wiper relay is located in the jack compartment.

Sometimes I would operate my rear wiper then I would shut it off but upon restarting my truck I would hear it running?!
One day I had had enough so I left the ignition in the on position and went to the back of my X. I noticed that the wiper arm was not in the right position to be completely parked,so I manually parked it and it shut off. This might sound like a pain in the ass but to figure out how to get this arm to park properly was a project,so when I use my rear wiper if I hear it running I just walk past it and park it!!!

i was unable to park it myself...it all started happening after a trailer rammed my back hatch and ripped the trimming off. maybe that has smth to do with it (not the trimming, but the ramming)

The rear windshield wiper on my 94 Explorer wouldn't work right. It would run a half cycle, the quit in the non-park position. Sometimes you could jiggle it and it would return to the "park" position. I fixed the problem myself with a little time and no cost. This is how:

Pull the rear wiper blade straight back to remove it. Remove the four "push pins" or "buttons" (older Explorers have screws) which hold the plastic cover to the top of the rear deck. This can be done carefully with a putty knife or similar tool. Pry up the bezel which surrounds the rear inside door lock. Remove the hidden Phillips screw inside. Remove the two Phillips screws which secure the inside strap. And remove the strap. Gently remove the plastic panel by sliding it towards the top of the liftgate.

Peel back the plastic inside cover enough to expose the motor. Disconnect the motor wires (3) and remove the motor by loosening the three Phillips screws.

Remove the plastic covers from the motor assembly -- a small circuit board is inside.

Remove the brush assembly which partially serves as a reversing device for the motor. There will be four beryllium copper brushes. This will expose a round circuit board which turns with the wiper shaft. This completes the reversing device. Mine was full of old hard grease which had come from the worm gear assembly. The excess hard grease would not allow the brushes to make contact with the round circuit board. Clean the old grease off with solvent and bench test. Put the motor back together and reinstall. I don't know what the dealer would have charged to replace the motor, but it would have been a lot more than I paid!
