My 04 f-350 wipers quit working the other day. Thought it was the motor, but turned out that it wasn't that. I took the motor and plugged into another vehicle and it worked fine. It makes a click noise when you turn the wiper **** to on and I do have power at the plug at 3 out of 4 places on the plug. Now my question is could the problem still be in the turn signal/ dimmer/ wiper switch?

 

Checked ground ???

 

what wire is the ground

 

Have you tried to manually move the wipers with the motor disconnected to see if the thing is binding?

 

If in need of wiring diagrams autozone has them.

Is the click sound the "safety" going on --- over current with the motor in stall?

 

Clicking sounds like to me an relay

 

where is the relay located?

 

2 in the Battery Junction Box the way the diagram reads

 

I'll look tomorrow. Thanks
