If your motor is audible and your fuses and connectors are okay, you may have to take a close look at the plastic gear parts up in the roof. The nylon parts do wear out since they are in the roof and more exposed to different temperatures. If any of that mechanism fails then your sunroof will stop working even if the motor is still good. It is a bit of a PITA to get to it since you will have to remove the headliner to get at the mechanism and then identify the worn part and replace it CAUTION: The sunroof system is timed from the factory so that the motor shuts off automatically when the sunroof window reaches a certain position. Extreme care must be taken when removing the motor, timing may be thrown off causing possible damage to the sunroof system. Anytime the motor is removed from the sunroof assembly the sunroof glass panel must be in the FULLY CLOSED POSITION or the unit will be out of timing. The drive motor cannot be reset to the park position after being removed.
CAUTION: The sunroof motor should only be powered through the vehicle battery and sunroof wire harness. Applying power to the sunroof motor leads will cause failure of the control module.

Test
No leak!
Ta-Da!

You need a special puller for the inside door panel. Have to go to an autoparts store for it. Then you take out all the screws on the door panel. The you use the puller on the bottom and sometimes the sides to LOCATE and REMOVE the fasteners..Lift the panel up and away from the door. Careful about any wires that might be connected to switches. Unplug those if present. You will now be looking at a sheet of sound deadening material that has a tar like substance on it. You cannot really save this and it is messy. remove it and then you can see the internal door and window parts. Be careful because the parts are sharp. Long sleeves and gloves are recommended. See if you can reach in under the window and feel for the bolts. If you cannot then the window has to be removed. Locate and remove the glass retainer and remove the window. Then remove any bolts holding the window mechanical parts. Then you should be able to get to the bolts for the mirror.

Important: This sunroof system is timed from the factory in order to allow the actuator to shut off automatically when the sunroof window reaches a certain position.

The sunroof is powered by the same circuit breaker that power's your power window, so if your windows work than the circuit breaker should be good. You needed test the switch to verify if works with; on the factory sunroof system the roof is controled by a sunroof module the module receives a signal from the switch then throws voltage to the sunroof motor. The motor and module are located between the sunroof assembly and windshield underneath the head liner. You would reconnected the switch and test to see if the sunroof motor is getting power when the switch is in use by testing the dark green wire when closing and a light green wire when opening. Test these wires at the sunroof motor with a ohm meter or test light. Also, check this procedure to repair...

Hope helps (remember rated this) Good luck.

There is a great possibilty that there is a leak on the Left Side of the Windshield. It is most likely in the area of the upper left side.
The reason for this conclusion is:
The rain water is coming in the Left Upper Side; and either coming down the "A" Pillar, or traveling underneath the trim on the inside roof and coming down the "B" Pillar.
The only other explanantion is a torn, worn, cracked or dislocated Weather Seal on one or both of the doors, allowing rain water to come in. Inspect very carefully these Weather Seals, especially on the top front portion of the rear door.
To help you locate these after a hard rain:
Take the trim panels off the "A: and "B" Pillars and the Roof Line above both Doors. Check for wetness underneath the trim. Or take these trim panels off, and place folded paper towels under the trim panels; reattach the trim panels and wait until it rains. Afterwhich, take these trim panel off and check the paper towels for wetness.
The Windshield Seal is easily inspected for cracks and tears.

The rear temp blend door is stuck in the cold position ,very common problem on vehicles with rear HVAC units . There is no valve , electric actuator !
Air Temperature Actuator
The air temperature actuator is a 3 wire bi-directional electric motor. Ignition 3 voltage, ground and control circuits enable the actuator to operate. The control circuit uses a 0-12 volt linear-ramped signal to command the actuator movement. The 0 and 12 volt control values represent the opposite limits of the actuator range of motion. The values in between 0-12 volts correspond to the positions between the limits.
When the HVAC control module sets a commanded, or targeted, value, the control signal is set to a value between 0-12 volts. The actuator shaft rotates until the commanded position is reached. The module will maintain the control value until a new commanded value is needed.
