Sunroof part 2

Someone does not like me at all. I have not even made the first payment and the truck is back in the shop with the sunroof problem again.

If you recall two weeks ago my sunroof would not close once it reached the vent position. I took it to a local dealership (not the purchasing dealership because it was getting ready to rain). Well it took 5 days to get the sunroof fixed or so I thought it was fixed.

I took the truck on a trip this past weekend I had not opened the sunroof as I did not need something to happen while I was 500+ miles away. So today on my way home from work I decided to be adventuress and open her up. She opened up much faster than the factory one did. At this point I was thinking sweet, I decided to close it to test it out and it went into the vent position and it stopped just as the last one did. I opened it up and tried to close again stuck in the vent position. At this point I am getting very pissed off I was lie WTF did the dealership not try it out before giving it back to me. I would have tried it when I originally picked it up but I could not be w/ out the truck again or the trip was out so I would wait until I get home from Atlanta.

My dealerships service department was closed but I spoke to my salesman who was able to get the service manager to put it in the shop. So the good news is that it's back at the purchasing dealership the bad news is now I am back at square one with this sunroof. I am starting to believe that either Courtesy Chevrolet did not really change any parts or they did not know WTF they were doing. I hope my local dealership will have better luck.

This bulletin is being revised to update the correction information. Please discard Corporate Bulletin Number 05-08-67-002 (Section 08 -- Body and Accessories).

--------------------------------------------------------------------------------

In the event that one of the following conditions occur, perform the reinitialization procedure listed below prior to following SI for diagnosis.

• The sunroof module has driven the mechanism out of the rear of the assembly preventing the sunroof from closing.

• The unit will not close fully.

• The sunroof appears to be jammed or cycles forward and then stops early.

Sunroof Motor/Actuator Synchronization Procedure

Synchronization will be necessary any time the sunroof motor is removed from the unit. The sunroof module is synchronized when the motor controller learns the full vent position.

To synchronize the sunroof:

(Please read directions completely prior to beginning the procedure)

Turn ON the ignition with the engine OFF.

. DO NOT OPERATE THE SUNROOF GLASS IN THE OPEN/TILT DOWN DIRECTION UNTIL THE INITIALIZATION PROCEDURE IS COMPLETE OR SERIOUS DAMAGE MAY OCCUR.

Using the close/tilt up portion of the sunroof switch, operate the sunroof glass until it reaches the full vent position. Even if the sunroof stops early, proceed to step 4.

Continue to hold the close/tilt up portion of the sunroof switch for at least 30 seconds or until you hear a slight click from the front of the sunroof mechanism.

The slight clicking noise at the front of the sunroof confirms the initialization is complete.

Verify that the system operates normally.

Once the synchronization is complete, the position of the motor and mechanism is stored in the memory of the sunroof motor controller. The motor controller retains this memory even if power is disconnected to the motor.

If reinitialization does not correct the concern, perform the following steps:

Reference SI and use the R&R procedure for removing the complete sunroof module assembly.

Remove the motor from the unit and force the Pin Guides forward until the hard stop is reached. If water channel guides are out of track, there may resistance to moving pin guides forward. If water channel guides are out of track you will need to feed them through the rear of track. Make sure both sides are in complete forward position. In the event track mechanism components are damaged, use Service Kit P/N 88979948. Reference SI Document ID #1364848 for replacement procedure.

Once the track mechanism is repaired, reattach the motor and follow the reinitialization procedure listed above.

Check for proper operation.

<{POST_SNAPBACK}>

Waaaay back in the day I bought a brand new 1992 Sentra SE-R, fully loaded with everything including leather. My sunroof would intermittenly not close and drove me batty. Finally got it to the service guy when it wouldn't close and they replaced the switch. Same problem re-occured. After about the 4th or 5th time they finally replaced the motor and never had the problem again. On mine you could pop out a small plastic cover and using an allen wrench you could manually crank it closed. Unfortunately I got pretty good at cranking this closed.
