How can I bench test test the wiper motor and window motor before I install them to rule out other issues in the truck.

Thanks all.

 

What are the doing? On the wiper motor, I had 1 speed. Wide open, no slow or intermitant. There is a "govener" between the wiper switch and motor that doesn't show up on junk yard lists. In fact they don't even show it. It is about 2"X2" and located behind the dash on the left side behind the light switch and wiper switch. On the door window motor, does the motor run but the window not do anything or just go down? Mine did that. There is a gear section that is located on the end of the motor that has 3 plastic cam/bearings. When these disintrigate the motor will run but the window won't go up, without help. It will go down FAST. Check other posts on this problem. There are kits to fix this problem.
