Just bought this as "errand truck". Following things Don't work:
Power windows
Wipers
Washer pump
Radio

Fuses and relays are good. Haven't gotten to all switches but this seems like the module. Am I missing something?

Hi Ride,
I added the wiring schematics for your power windows and washer pump. It looks like the common components between those two are fuse 11 in the battery junction box and ground 4. Ground 4 is shown in the image of the truck. Grounds are always a good place to start. There should be almost no power at a ground. Using a voltmeter can determine that but what you are looking for first is the general condition on the ground.

This article will teach you how to use a voltmeter, if you don't already know how to use one.

Best of luck!
