Hello All..first off i want to say thanks for this forum..i have saved a ton of money and even more valuable i learned a ton about my 99 F150...some things i have learned are great...but now i have realized i waiting on some gremlins to appear..anyway here is my question..my drivers side power window is acting up..when rolling down about 1/3 of the way down it really drags and i need to help it down by gently pushing on it..after 1/3down point it goes down perfectly fine..rolling up it goes up like a rocket. I have removed the panel and lubricated but it has not helped...any ideas at all??? Im stumped..thanks in advance!

 

my 01 does the same....if you figure it out let me know...but mine also goes up slow

 

Here is a TSB I have found, it states drivers door, but I would assume the passenger door would be subject to the same issue over time.


FORD: 1997-2002 F-150


ISSUE:
Some vehicles may exhibit a driver's side door glass that binds when operated. This may be caused by the inner door panel developing a crack where the rear window run attaches. When the window is operated, the run flexes and causes the glass to bind in the run.

ACTION:
Install a Reinforcement Plate Kit (XL3Z-15211B06-AA) on the inner door panel. Refer to the following Service Procedure for details.

SERVICE PROCEDURE
Remove door trim panel per the appropriate model year Workshop Manual.
Remove the current rear window run attachment bolt and discard.
Hold reinforcement plate (included in kit) in position ( Figure 1 ) and mark the area where it will mount.
Use sand paper to rough up the area where the outer edge of the plate will mount.
Apply TA-12 Structural Foam to the reinforcement plate.
Place reinforcement plate in position and install the new bolt and washer assembly (included with kit). Torque the bolt to 8.4-11.5 Lb-ft (11.4-15.6 N-m).
Using the five holes around the perimeter of the plate as a guide, drill 3/16 inch (4.76 mm) holes in the inner door panel and install five rivets (included with kit).
Apply heat gun at 120° F (49° C) for up to 20 minutes to cure the Structural Foam.
Re-install the door trim panel.
Verify proper operation.


EDITED TO ADD: THIS IS NOT THE SAME DOOR CRACK THAT THE 97-00 TRUCKS WERE SEEING ON THE DOOR SKIN, THIS IS WHERE THE WINDOW TRACK BOLTS TO THE LOWER PART OF THE INNER DOOR SKIN.

 

Thanks for the TSB info..i looked up the part and i can get it for about 100 bucks delivered...i have searched all over to see if their are any write ups on the topic and have come up empty. Has anyone had this issued and repaired it via the TSB instructions?

On another subject i will be replacing my power lock actuators..i will take as many pictures as i can of the removal and install of the new part and will post them after its done..wish me luck..from what i have read about the actuators it a bit of a pain.
