Question about 2003 Pontiac Sunfire
I recently had a first occurring problem with my moonroof being cocked to one side, i fixed the probelm by removing the motor and readjusting the snake rods attached to the moonroof however, when i begun to close the roof it stop with the front part closed but the rear still open
what did i do wrong???
Do you know how to test automotive electrical circuit's with a DVOM - digital volt ohm meter ? When adjusting the moon roof did you see any switches ? sunroof limit switch
Measure the reference voltage of the sunroof limit switch soft stop signal circuit at the sunroof control harness connector to a good ground.
Does the reference voltage measure near the specified value?
Notice: Do not open the sunroof glass past the full open soft stop position. Doing so may damage the sunroof assembly and or the roof top.
Connect a jumper wire to the sunroof limit switch soft stop signal circuit at the sunroof control module harness to a good ground.
Turn ON the ignition, with the engine OFF.
Using the sunroof switch, operate the sunroof system, not to exceed the full open soft stop position.
Does the system operate as requested?
Do you know what a wiring diagram is ? Free one's here

Power Sunroof System Components
The power sunroof system consists of the following components:
• Sunroof control module
• Sunroof motor with the limit switches
• Sunroof switch
• Sunroof glass-spoiler type, with glass sliding above roof
• Rail and track assembly upon which the sunroof glass rides
• Power sunroof system circuit breaker: PWR WDO 25 A
• Ground: G204
Sunroof Limit Switches
The sunroof limit switches track the position of the sunroof glass through two limit switches:
• Soft Stop limit switch through the sunroof limit switch soft stop signal circuit
• Vent Stop limit switch through the sunroof limit switch range signal circuit
The sunroof control module monitors the limit switches and based on the input combinations, determines the position of the sunroof glass. As a sunroof limit switch closes, the 5 volt reference will be shorted to the sunroof limit switch low reference circuit, pulling the 5 volt reference to 0 volts.
The sunroof control module monitors both sunroof switch input requests and based on the sunroof limit switch input combinations, will control an output to the sunroof motor, to drive the sunroof glass to the requested position.
The sunroof has a bi-directional motor. When the motor is not operating both circuits are grounded. When the motor drives the sunroof glass in the direction from the closed to vent or vent to open position, the following occurs:
• Voltage is supplied to the sunroof motor open circuit.
• Ground is maintained to the sunroof motor close circuit.
When the motor drives the sunroof in the direction from the open to vent or vent to closed position, the following occurs:
• Voltage is supplied to the sunroof motor close circuit.
• Ground is maintained to the sunroof motor open circuit.
The sunroof control module is equipped with a timer circuit which stops the operation of the sunroof motor after 8 seconds.

sounds like your sun roofs gear or track is stripped. Replace the motor for the side window had the same problem there really cheap.

You would have to remove door panel and remove the two nuts fastening the window to the window motor regulator then slide window up and use tape to hold it up until you can get it repaired

OMG. I replaced the battery in my 06 G6 and had the same problem. the windows would not roll up or down how they did before. I read the answers on here and it does work. Hold up the window switch for ten seconds and it resets. You will have to do it to each window. Worked great. Thanks

by using a simple test light you can check each post individuly with the switch in each position also at the motor end check where the wires go into the motor have someone work the switch in each position and test each wire if you have fire going to the motor corrsponding to the switch position (you should have fire on at least one wire in both closed and another wire in the open position of the switch at the motor) and if so then your motor is probably out

If this occured after trying to close the shade while the moonroof was opening, it is possible that the plastic tab that locks into the vent (and subsequently the rest of the moonroof) has been bent. I was having a similar problem where my vent would only go up on one side and stay closed on the other (and it would sometimes get stuck open). It would also prevent the rest of the moonroof from opening up. If this is the case, from what I can tell, there is no easy fix for this. Upon researching this problem, you are the only other person asking about it and zero fixes. For the time being, the vent can be closed by lifting up on one side to "unlock" the stuck tab and you should be able to put it down. After that, you should look up instructions to remove your moonroof glass to see if you can inspect the affected area to determine the cause. Here is a link that shows you how to remove the moonroof glass, but does not address the exact issue you describe.
