2001 yukon sunroof stuck in tilt position

It sound like you have a gear problem in the motor need to remove motor and replace it or replace the gear

1. Place the ignition switch in the ON position.
2. Push and hold the sunroof switch toward 2 . Once the sunroof has reached the full tilt position, release the switch. Push and hold the switch toward the 2 position again. After a delay of four seconds, the sunroof will make a small movement and backup.
3. Release the switch.
4. Within 5 seconds of releasing the switch, push and continuously hold the switch toward 2 . The sunroof will move from the tilt position to the open position and back to the close position.

In the under hood junction box , fuse CTSY LP 15 amp . Instrument fuse panel PWR WDO CB 25amp .
Sunroof Motor Synchronization
Synchronization will be necessary anytime the sunroof module battery positive voltage circuit is interrupted. The sunroof module will be synchronized when the controller learns the full vent position. The sunroof system will ignore any open request until the system has been synchronized.
To synchronize the sunroof:

1. Turn ON the ignition, with the engine OFF.
2. Using the close/tilt up portion of the sunroof switch, operate the sunroof glass until it reaches the full vent position.
3. Verify that the system operates normally.

Once the sunroof glass reaches the full vent position, the actual position is stored in the memory of the sunroof module. The sunroof module will stop the motor one motor revolution before the defined actual positions
Hope this help ! good luck !

To reset the moonroof one-touch operation:
With ignition switch in the "ON" position, do the following:
1. Push and hold the "TILT UP" side of the switch until the moon roof tilts all the way up and then tilts down slightly (approximately 10 mm [0.39 in.] at the rear).
2. Check for proper operation of the "one-touch slide open/close" and "one-touch tilt up/down" functions by pushing the switch briefly to the "SLIDE OPEN" and
"TILT UP" positions.

see the diagram attached and fix it. God bless you

it probly cam off track if u can get something in there to push it along a little it will probly go down

Is there a way to manually close the sunroof in the up position on a 98 Nissan Maxima?

hi the relay for this might be stuck, check fuse box for relay, if not in there, ( i assume the switch for the sunroof is in the head lining above in the center ) remove the panel for the switch and there might be a relay in there, alternatively you should be able to manually close it, this should be in the same place.....hope this is correct

H Kim -

The "gearbox" is unfortunately under the headliner with no easy access. If you are also experiencing a clicking sound when the motor is activated, the regulator track had slipped position and will need to be reset.

I have been through this problem twice now. The first time the motor / gearbox came loose from it's mounts, began slipping (click, click,click), very nasty sound. I remounted the motor with threadlock on the screws, but alas.. two years later (mine's 2006) it slipped again.. I don't know why yet, I need to drop the headliner once more and have a look. If you would like a copy of your FSM, drop me a line.

Here's the RESET procedure from the FSM, absolutely gospel, no other way to fix it:
Sunroof Motor Assembly Note: Note • If the guide is removed, initial position setting of the sunroof motor will be required. After installing the sunroof unit, perform initial position setting using the following procedure. 1. Press the TILT UP switch to fully tilt up the glass panel.
2. When the glass panel reaches the fully tilt up position, temporarily release the TILT UP switch and press it again for approx. 13 s continuously. Continue pressing the switch until the glass panel automatically stops at the fully tilt up position after reaching the mechanical lock position.
3. When the glass panel stops at the fully tilt up position, temporarily release the TILT UP switch, then press it again within 5 s and hold.
Note • Press the TILT UP switch continuously until the glass panel opens to the fully open position, returns to the fully closed position and then stops. 4. Release the TILT UP switch when the glass panel stops at the fully closed position.



ALSO, Here's the clearance adjustment specs for having the glass panel in the correct resting position:


GLASS PANEL ADJUSTMENT
1. Fully close the glass panel.
2. Measure the gap and height difference between the glass panel and the body.
3. Loosen the glass panel installation screws and move the glass panel to adjust.


Standard clearance a: 0.2-2.2 mm {0.008-0.08 in} b: 0 mm {0 in} 4. Tighten the screws.
5. Insert any available thin plastic card between the weatherstrip and the body, and verify that they are sealed. (There is resistance when the plastic card is moved.)


• If they are not sealed, perform Steps 3-4 and adjust again.

tilt the sunroof into vent position as far as possible then press and hold the same switch for 30 seconds until you see it move release the switch and immediately press and hold it again the sunroof will close and open fully then close again do not release the button until it reaches the closed position for the second time.
