Sun Roof issue's

So it just started, I push the button to go back and it moves a few inches.

It works nothing like it should, to get it to go up I must hold the button.

Could it be the switch or the motor ?

Could you be more specific? The sunroof switch has 7 positions. Rest, back full, back part, front full, front part, tilt full, tilt part. I'm about 100% sure that my terminology is wrong, but I think you know what I'm talking about.

Check the 6 positions that cause the roof to actually do something. What happens in each case? Is it repeatable or completely random? Not only might it be a switch/motor, but it might be a mechanical problem. I'm sure there's a way to test the switch with a DMM. I'll look it up in the service manual tonight.

Try this. I was having problems with my sunroof awhile back too. Taken from my thread - https://acurazine.com/forums/3g-tl-problems-fixes-114/sunroof-wont-tilt-auto-open-close-have-hold-button-close-open-fully-854890/

Moonroof motor calibration

NOTE: The moonroof calibration must be performed when any of the following events have occurred.

The moonroof is manually moved with the battery dead or disconnected.
The moonroof motor is replaced with a new one.
Any component related to the moonroof replaced.
- Wind deflector
- Moonroof glass
- Moonroof seal
- Moonroof glass bracket
- Moonroof cables, etc.

To calibrate the moonroof, perform the following steps

Turn the ignition switch ON (II).
Open the moonroof to full open position and release the open button.
Pull and hold the moonroof OPEN switch until the moonroof glass moves slightly back to its mechanical stop and then forward again slightly.
- New Motor
- Other than new motor: This will take about 13 seconds.
Release the OPEN switch.
Within 5 seconds, pull and hold the moonroof OPEN switch again.
In about 3 seconds the moonroof glass will begin to slide closed.
Continue to hold the open button until the glass moves to closed position, tilts up, and returns to the closed position again.
Test the moonroof auto operation.

If that doesn't work, try this one

I search the site some more and found the following:

To reset the moonroof control unit, do these steps.
1. Close all doors and trunk.
2. Turn the ignition switch OFF.
3. Press and hold the tilt switch, and turn the ignition switch ON (II).
4. Release the tilt switch, and turn the ignition switch OFF.
5. Repeat steps 2 and 3 four times.
6. Press and hold the moonroof open switch until 3 seconds after the moonroof is fully opened.
7. Press and hold the moonroof close switch until 3 seconds after the moonroof is fully closed (tilted).
8. Confirm that the moonroof control unit is reset by using the moonroof AUTO OPEN and AUTO
CLOSE function.

I followed the instructions and presto, my moonroof works just perfect now.
Hope this help too

The moon roof calibration - either method - oh so intuitive! This is a great post for those who will need it. Certainly, no one would guess these steps on there own!
