Reply to lostrider's Post: i already have all that information but i dont know where those points are located. i have no wiring diagram. where is that connector located and how do i get to it?
Expert:  lostrider replied 6 years ago.
Look on the drivers door pillar at the vehicle info tag and tell me what the trucks build date is, there are 2 different module configurations based on the build date.
Customer: replied 6 years ago.
Reply to lostrider's Post: sorry it took so long but the truck isnt here and my granddaughter could not find the tag. any way someone helped her and the date is 10/02.

thanks

Jerry, the early build date sunroofs have a seperate motor and module, the headliner needs to be accessed to do the diagnosis, thats where the connector is.

Roof Opening Panel Module

Removal and Installation

NOTE: This procedure is for early build vehicles only. Late build vehicles use an integrated roof opening panel motor/module.

NOTE: If installing a new roof opening panel module, the original motor and module must be replaced with an integrated motor/module. The new integrated motor/module is part of a kit which contains all the parts and instructions needed to convert the roof opening panel system to use the new type of motor/module. The new motor/module must be initialized before it will operate correctly. Refer to the instructions included with the conversion kit for the initialization procedure.

  1. Remove the headliner.
  1. Remove the roof opening panel module.
    1. Disconnect the electrical connectors.
    1. Remove the three tie strap retainers.
    1. Slide the roof opening panel module from the retaining bracket.
  1. graphicTo install, reverse the removal procedure.
    • Install three new tie strap retainers.

Customer: replied 6 years ago.
so is this a common problem and i should start there?
and does the headliner come out easily and go in easily?

and will the sun/moon roof in the open position going to cause me any problems

any additional advise or pointers you want to give me
Expert:  lostrider replied 6 years ago.
Its a common problem, the early build date motors and modules have been replaced by the later build date motor/module combos, the headliner is fairly easy to remove, just remove all the trim panels necessary, the sunroof in the open position is in its own track and wont cause any interference with testing, the only advise is to take your time and follow the pinpoint test.
Customer: replied 6 years ago.
thank you!
Expert:  lostrider replied 6 years ago.
your welcome, when you get to the motor, take a small hammer and tap on it while pressing the close button, if the contacts are stuck that might free them up.
