Door Panel Removal

Associated Hardware

  • Once you have the door panel removed, you will need to access all associated hardware for the door channel bracket. These will be the two bolts located near the front edge of the door frame. Remember, you will need to loosen these and do not fully remove them from the door.

  • Next, moving to the guide rod, you will only need to loosen the upper nut. The lower nut on the bottom edge of the door can stay tight; there is no adjustment at this location.

  • Then, you will want to loosen the upper bolt for the rear guide; this is located near the lock rod on the back edge of the door frame.

Adjustment Procedure

  • Now that we have all of the hardware loosened, it is time to start the adjustment procedure. Begin by completely rolling the window up to its highest position. The door glass will need to be set within the run channel. If you need to, you will be able to reach in from underneath and push the glass from the bottom side if it is not fully seated just from the motor alone.

  • Now, begin by applying slight pressure on the rear guide until it makes contact with the door glass. This guide needs to make slight contact with the glass. Now you can fully tighten down this bolt.

  • Moving forward, tighten down the upper guide rod mount nut. Next, apply inward pressure to the front channel bracket. Ensure there is contact with the glass and then tighten the top bolt first, followed by the bottom bolt.
