Windshield wiper trouble

[motorbikejedi]

I am trying to figure out why neither my wipers or my washer is not working. I have only hi and low speed and the sprayer which are all run off the blinker arm (I'm not sure what it is actually called). I jumped the wiper motor and it still works. Is there anything other than the switch that would make both stop? I was looking at the wiring diagram and it looks like they both share a ground, does anyone know where its grounded so I can check that? The truck is a 1987 with the 2.5 2wd if it makes a difference. I was thinking of just cutting the wires going to the switch and add my own switches, but i don't want to do that unless I am sure that is the problem, I will try bypassing the switch, but I'm not sure which wires to jump. Any help would be apreciated

Thanks!

Manual tranny?

 

Leaking clutch MC?

 

Corroded fuses?

 

Burnt fuse?

 

Bad intermittent wiper relay?

now that you mention it, one of the fuses looked a bit corroded, I'm gonna go jump it and see if that works

After lots of trouble shooting and headache I found that it was a rusty connection at the circuit breaker. If I would have realized which one was the circuit breaker I would have found it first thing, Its the metal box at the bottom of the fuse box, i would deffinitly check that for bad connection, if anyone else has a similar problem.
