Rear Window 1988 4Runner no longer functioning

[Toyota_4Runner]

Having some issues with my rear power window on my 88 4Runner. Just recently it stopped working. I seemed to have tried everything and still can't figure out what the problem is . Wondering if anyone here might have any ideas.

I have removed the hardtop and replaced it with a soft top. The other day I accidentally hit the rear wiper switch and then turned it off, can't be 100% sure though if that was the last time I noticed it worked. Would this cause it to stop working?

Things I have tried
1. Tested the motor with 12V power supply goes up and down
2. Tested each switch in the circuit all function perfectly. Only one I didn't test was the cover-top switch
3. Switched out the Relay with another one. (Is there anyway to actually test the relays?)
4. Applying 12V to pins 1 and 3 on the relay connector powers the window motor
5. Doing the test on the relay connector as per the Service Manual produces these results:

8-G: 12V with Ign S/W On - PASS
6-G: Always 12V - PASS
10-G: Always Continuity - PASS
2-G:
a) Continuity with Back Window Limit S/W On - PASS
b) 12V with IGN S/W ON and Back windows limit S/W OFF - FAILS
c) 0V with IGN S/W ON and Back window limit S/W ON - PASS

4-G: 12V with IGN S/W ON and Rear power window switch at FREE position - FAILS
5-G: 12V with IGN S/W ON and Rear power window switch at FREE position - FAILS
11-G: 12V with Backdoor control S/W at FREE position - FAILS
12-G: 12V with Backdoor control S/W at FREE position - FAILS
7-G: 12V with IGN S/W ON - FAIL
7-10: Continuity in the relay with IGN S/W OFF - FAILS
9-G: 12V with rear wiper operated (Hard top removed can't test as no rear wiper)
13-G: Continuity with rear wiper retraction detection S/W ON - (Hard top removed can't test as no rear wiper)

Wiggling the relay while it's connected and the car is running I can feel/hear it clicking

All help is greatly appreciated.


Thanks

Toyota_4Runner,

I believe if your window wiper is not retracted all the way the window will not go up and down. Take a look at that. It might solve the problem.

What if the wiper isn't installed. I don't currently have my hard top on. It's a soft top and no wiper. Also it has been working fine with the soft top since May.

How does the rear wiper work with a soft top, since it's part of the hard top ??

And if you didn't bypass the both the wiper-retracted and top-in-place switches, the window won't move.

There is no wiper.

This was purchased last year used all year without any problems window went up and down without an issue. May of this year put the soft top back on and it worked without a problem. The only difference is I triggered the wiper switch on accident so I guess I am wondering if that is what caused the problem how can I possible trick the relay into thinking the wiper was retracted. But as I just stated I've never had a problem in the past with the soft top and controlling the window.

Thanks for the help

So I was able to resolve the problem. It ended up being a faulty cover top switch. Removed it and just placed a jumper in the connector. working fine now. Thanks to everyone for their help.

I have a 88 and 89 Runner and both have had rear window issues. Both rigs had the same problem. The window lock switch was the problem. I unpluged it at the cosole and there are 4 conections on the plug. I put 2 cross over wires diagnolly across the plug and they both work great. I never used the window lock anyway and the switch was $80.00
