My sunroof broke and flew out on the freeway and i cant find the sun roof

Hi.
I was having trouble with my sun roof on a 2004 Montecarlo. I had two issues water coming in and would not operate fully. I could toggle the switch and it would not move very far. this is what I found. I started to pull down the lining and saw that the motor was in front of the sun roof.
I found the drain lines on the front side corners of the tray around the inside of the sun roof. I found that the tube ran down the pillar's and out between the door hinge's. I took them off and blow them out one was plugged up. That fixed the water problem. The roof would move with help from me pushing. I got it opened and noticed the grease was hard. I cleaned up the grease and removed most of it with WD40.
Now the sun roof works good as new.
I thought the water problem was because the roof was not fully closed but I guess it is designed to have water pass by the roof seal and have it drain away. I always noticed water under the car after a rain or a car wash but did not realize iit was the sun roof draining.

caution if it opens you may not be able to close it again, this sounds like the track broke or something in the motor. lets hope its the motor as if its the track then the whole track needs to be replaced, there is no repairing a broken sunroof track.

CHECK SUN ROOF FUSE.IF GOOD CHECK FOR POWER AT SUN ROOF SWITCH.IF YES SUN ROOF MOTORS WIRES COULD BE LOOSE OR BROKEN OR SUNROOF MOTOR FAULTY.

replace the sunroof motor. the plastic gears in the motor are broke.

CHECK SUNROOF FUSE.IF FUSE IS GOOD POWER GOING TO SUN ROOF MOTOR.THE MOTOR IS BAD OR SUNROOF IS BINDING NEED ADJUSTING.IF NO POWER GOING TO SUNROOF MOTOR FUSE IS GOOD.YOU GOT BROKE OR LOOSE WIRE FROM FUSE BOX TO SUNROOF SWITCH.OR BROKE WIRE OR LOOSE WIRE AT THE SWITCH.

The sunroof has a relay between the fuse and the sunroof motor

remove the trim cover over the drive motor and test the motor connector for power when u try to operate the sun roof, more than likely the sun roof motor is defective.

The motor is stripped out. The sun roof might be binding on the sun roof track and the motor is not strong enough to move the roof. I would first replace the sun roof motor if available seperately.
You mihgt have to get the complete assembly because of part availability

LOWER ROOF PANEL UN BOLT MOTOR TO SUNROOF 2-3 BOLTS REMOVE MOTOR THEN SLOWLY PUSH SUNROOF DOWN TILL IT ALIGNS WITH THE ROOF THEN REINSTALL THE MOTOR AND ROOF PANEL.
