2013 XLT Crew Cab 140,000 miles, Here is my story...

A while back my front drivers side window quit working, the rest of the windows still function properly. Checked my fuses and they were all still good. I then pulled the door panel off and none of the regulator cables were busted, so I figured I would replace the motor. I replaced it with this one...

After installing, the new motor will lift and lower the window, yay. However after maybe about 15 seconds or so of running it, or if I hit the auto up/down on the switch the motor will run full up/full down then stop working completely. Unless I unplug the motor, plug it back in, then it will work again like previously until it stops again.

I then thought maybe the auto up/down function on the switch was the issue. I replaced the door switch with this one....

Tried it out and there is no difference with the window function. Now I am thinking my truck does not like the rock auto window motor. I order a replacement motor regulator assembly from my ford dealer, install it. Now this one doesn't move at all, no up, no down, nothing. Now I am wondering if maybe the motor was never an issue?

I am pretty much stuck short of checking continuity in the harness wires, but the fact that the Rock auto motor would at least run for a sec but not the Ford motor has me scratching my head.

Does anyone have any suggestions? I am at a loss.

Thanks,

 

I guess a quick check before you meter test the harness would be holding the switch in up or down position and wiggle harness and see if it moves. Also inspect the plugs and pins be sure they are clean and straight. When it was working did you do the auto up down relearn? One more thing and it's a guess that the body control module may have something to do with it. See if you have any codes. I seem to remember the bcm can shut things down to protect from over current. It doesn't sound like the door jam harness Ara to me but move that area also. Hopefully someone wiser than me will chime in. Good luck. Tim

 

I know it's a different year and a lot changed but maybe this could point in in the right direction. Maybe...

pulled the rubber cover off of the harness and did find that there were about 5 wires that did have the insulation cracking and exposing copper. I did a little surgery however this was NOT the issue. But while re-assembling the door I happened to notice where the harness was running through a hole in the door panel, it sagged enough to rest on the edge of the hole, and appears to have over time wore away the harness wrap, and severed a wire completely. A little soldering and now back in business, turns out the original motor still works.

 

I forgot about the wires in the door harness getting worn. My friends 2011 has this issue with the back door.

Glad it's working!!
