Is there any way that the Cadillac front sunroof drain on a ’99 Cadillac STS be cleaned?

What could be done very carefully is use compressed air to blow through the hole from the roof side where it starts in order to free and remove debris. One could run water down through it to flush it out; however, be careful not to blow the drain hose off the sunroof assembly or the headliner would need to be lowered to reconnect it.

What could be the problem when a blocked Cadillac sunroof drain on a ’03 Cadillac CTS won’t drain in spite of using compressed air to clear it?

In this situation, one would need to check the ends of the drain tubes. If the water is not going through and compressed air is not clearing it out, there is probably a problem with the drain tubes which will need to be replaced. To do this, removal of the headliner would be required in this vehicle.

What is the override function that is used to force a closing of the Cadillac sunroof window?

To override the system, the ignition must be turned on. Rotate the sunroof switch to the ‘close’ position. Press upward. The sunroof switch data 6 circuit or override circuit will become grounded at the sunroof module. As long as the sunroof module sees this input, it will continue to slide the sunroof window to close, regardless of the other sunroof switch data circuits’ inputs.
