89 FJ62 rear wiper don't work

[metalfabsteve]

So yea winter is coming soon and my rear wiper won't work. I tryed a search and that helped me with the washer problem (mine has a broken tube at the top of the hatch) the washer works on the button but the wiper is dead. I see that there are two relays in the rear quarter panel didn't know if those have anything to do with the wiper. Where is the fuse located for the wiper? The wires appear to be ok at the hatch. If anyone has any experience with this issue your help would be greatly appriciated.
b.t.w. this is my first post short of my introduction.

Cheers
Steve

Run jumpers to it from the battery.See if it comes on then, if not motor is shot. MIke

I just went through this issue (sort of)

When you hit the wiper switch, can you hear the motor running in the back door? As in, is the motor working but the wiper just isn't doing anything?

I had a similarish problem but with numberplate lights (I realize that they are in the lower half but the wiper is in the top half, however bare with me).... I found that the earth for the plate lights was actually through the tailgate hinges and supports.... no actual earth wire was connecting the lower half of the tailgate to the body/chassis.... maybe just maybe there is no true earth for the wiper motor... just a thought... and as someone said, supply power direct to the motor first to see if it works....

resurrection of an old thread. i’m trying to get my rear wipers working. 1989 fj62. there are three wires going to the motor a blue/red, a blue white and a blue black. there is a solid black screwed to the body of the motor i assume is ground. can anyone tell me what there three blue/? wires do? i’m trying to jump it to see if the motor is maybe not working but i can’t seem to get anything (which means the motor may be shot) but as i don’t know what i’m actually testing i don’t want to make that conclusion just yet

i have tried changing out my relay with an extra one i have and no joy. i also tried checking for power to the wires going into the fuse and only got .7 of a volt off one wire. not sure what that means.

fyi my fuse is fine

new update…i found the battery i was trying to jump the motor with was actually dead. a different battery and i have power at the motor with pos to blue red wire and grounding the screw. so motor is good. relay still unknown but i’ve tried two and neither work (both look clean and in good shape inside). fuse is good. any help as to how to trouble shoot the harness would be appreciated. it doesn’t sound like my washer motor is working either which i understand is on the same circuit

also i just tested continuity between wires at the relay and at the motor and all three are ok. so now it seems like it’s something between relay and switch or maybe i have two bad relays (but i don’t think so)

I'll answer both for me right now...yes, the motor is definitely running / yes, the wiper isn't doing anything. What's my issue?

either the nut is loose on the wiper arm where it is attached to the tapered shaft/pivot or the the "linkage" between the pivot and motor is bad.

can you manually rotate the wiper arm easily?

 

[22590FJ62]

I can easily manipulate the arm, yes. And it looks like someone installed a new blade but it is too long because the arm hits the top of the door when manually maneuvered.

get the correct length blade

at the bottom of the wiper arm is a cap that pivots up out of the way to get to the pivot stud and nut. make certain the nut is tight on the stud. it is a tapered shaft on the stud, tightening the nut will hold the arm tight to the stud.

Absolutely will! Thanks man.

OK...old thread, but I didn't hear the solution to the problem? I've got the same issue. I just replaced the washer tubing where it was broken right where it exits the the car into the lift gate. Funny thing, though, my wipers didn't work at all, but when I pumped water through the broken tube and it dumped out along the rear passenger side lo and behold the wipers started working.

Why did my wipers work when the blue-white was broken, but they don't work now? Checked the motor and it is good.

So, I replaced the tubing and butt spliced the broken wire. I can now squirt water on my liftgate window, but my wiper does not work? WTF?

FYI...this is what I did to replace the washer tubing:
First I cut the tubing on the pump-side of the blue check-valve (passenger two-screw cover area of the lift gate). I gently removed the rubber boot between the car and lift gate on the passenger side and pulled wire and tubing out of the lift gate and separated the tubing from the wires which were wrapped with electrical tape (wire disconnect in same area as check valve). There is a white union behind the dome light and I used it to couple in the new 1/4" vinyl tubing (0.17" ID) that I got from Ace Hardware and pull it from the passenger side to the dome light. Use a stiff wire with a part loop to grab the tubing, Once a length of tubing was pulled from the passenger side and out of the dome light opening, I opened the drivers side rear vent and fished the old tubing with new tubing attached out of the vent. Connect new tubing to white union behind dome light...everywhere else...and done!

I'm having a similar issue, but the arm is stuck upward in the 12:00 position, I can hear the motor but the arm won't move and I can't manually move it at all.

IIRCC there is a small enclosed linkage piece between the motor and the pivot, maybe something in there is all bound up??

Okay thanks. I’ll open it up tomorrow once the rain ends.
