So my rear power window stopped working and I've tried all the tricks to get it working, but it looks like the motor is dead.

Anyone know where I can get JUST the motor? Ive only been able to find the whole assembly

 

Welcome to the club! I bought my truck in February of 2009 and that following October the window stopped while at campus. Pulled the seat and the cable was a rat's nest! I've read of it happening. It comes as an assembly and I plan to finally replace it this summer. I have opened it by hand the last 6 years.

 

Its not just me? LOL Yeah mine was broken when I purchased the truck used from Carmax. I told the salesman I'd buy the truck if they'd fix the rear sliding window. Deal!

I think they just did a quick patch up on it. It lasted a couple years and stopped working again last year.
My motor works because I can hear it, but the cable is toast so it doesn't move. Part of the cable is poking up between the glass and rear seat. I tuck it back down on occasion.
Sooner or later I'll find the time to remove everything and replace the motor/regulator assembly.

I haven't even searched to find the part# yet. Have either of you done that yet? I don't know how much it's gonna cost to replace.

 

When I first had looked years ago it was around $150. I bet between 100-150 would be right.

 

Its pretty common thing. After some research the three common fixes are
1. Tap the motor with a hammer a few times
2. Lube the cables
3. Clean the switch contacts (same as the regular window switch problem)

Ive had to clean the switches a few time already, but this time I could tell it was the motor.

Heres a link to the whole assembly for about ~$150. Dealer charges $600-700 with labor, but it seems easy enough to replace yourself.

This thread motivated me to finally jump on it. I watched a Youtube vid as to how to remove the rear seat back to gain access.
I just came back in from removing the motor and cable assembly. Wasn't hard, took me 20 minutes. I got the part# from it too. 6L3Z1523394AB
The cables are shredded and wadded up in a rats nest at the motor. Looks like I'll have to order one from the Tasca parts link you provided. Seems like a fair price.

 

The windows are made by C R Lawrence...I think you can also buy motor assemblies, as well as whole windows through their dealers...they make everything for residential/industrial glass, and automotive...not sure if it is any cheaper through them than a Ford dealer...

 

Yogi.kudos, if you're interested Ill sell you the motor from mine. Like I mentioned above my cable assembly is trash but the motor seems to work fine. Looks like Ill need to buy an entire motor/regulator assembly as a kit so this good motor is just gonna go to waste. I have no clue as to what its worth so make me an offer.lol
Im at work now but if interested send me a pm and we'll talk later.
