Ok i am getting down to the final stuff on re-assembling my cab and ran into a problem with the drivers side window. I have replace the motor/regulator, all of the felts and seals, and lubed all of the tracks but the window will not roll all of the way up on its own!! It stops about 1/3 of the way up and acts like it is in a bind. Have tried lubing the felts, adjusting tracks, loosening bolts, and pretty much everything we could think of and it only gets worse. The only way to get the window up is to pull the glass toward the rear of the truck and up. Any suggestions???
