I have searched. 1985 4runner. The rear wiper has never worked. I bought the truck about a year ago and have learned alot about working on the mechanics of the truck. However, when it comes to electrical stuff, I don't know where to start. The rear window works fine, but the wiper switch does nothing. How would I begin to diagnose this problem. Where should I check for power first.

Please answer this question as if I know nothing of electronics. Because that is pretty much the case. Thanks

This will get you started;

 

Tied in with the rear window. Make sure the connector inside the driver's side rear pillar (in the shell) is plugged in:
