2004 wiper issue

Good Evening everyone. We have a 2004 4 door, V6 automatic/4wd. The wipers stopped working. We replaced the switch and motor. The 20 amp fuse under the dash is good. I believe the only thing left is wiring unless there is another piece. Any ideas what this could be? Everything in the truck is factory/stock with no mods. Thank you for any info you can provide.

 

I would start with checking the ground (Pin 4 White/Black wire) at the motor, Low speed wire (Pin 5 Blue/Black) should have power with the switch on low, and the High speed wire (Pin 3 Red/White) should have power when the switch is on high. See what your missing and go from there.

 

Definitely get out the milti-meter and check all the wiring/plugs before throwing the parts shotgun at it.

A bad ground is definitely a good way to make nothing work.
