Just had my 03 extended cab at the body shop to fix some rust under the interior part of the doors both sides so they had doors off the truck and had the door panels off, now after I got it back my passenger side window is slow to go up and down just in the middle part of the window, I mean I don't think the body shop would matter it's just probably my window motor goin out? How hard is it to replace?

 

It could just be the regulator binding. I'd take it back to the body shop and have them check it out.

 

Turns out regulator motor is getting weak
