HI, yesterday I used my sunroof ....opened it and the it want not close. So now I drive with an open roof. I live in Spain and nobody knows much about Cadillac.
The roof botten feels the same as always, but the roof motor makes no noice at all anymore. Its just stuck in open position. Next to the roof bottom, I have the tilt bottom. If I use that, I hear the motor running up and down. I did check all fuses under the back seat and in the engine room. All the fuses seam okay. Anybody out there can help me with some input about my roof problem ? Do I have to take down the inside roof to get to the mechanic of the sun roof ? This looks quiet difficult. Please, if anybody has been working with this, let me know. Thanks Fred

DIAGNOSTIC AIDS
The Power Sunroof Actuator Limit Switch can cause the sunroof not to respond correctly to the Power Sunroof Switches with a short to ground or an open. Refer to Circuit Testing and Wiring Repairs at Diagnostic Aids under Diagrams. If the circuits test OK, measure the resistance of the Limit Switch. Resistance should be indicated in the sunroof positions mentioned in the Power Sunroof Circuit Description, otherwise an open should be indicated. An intermittent or poor connection can also cause the sunroof not to operate normally. Refer to Testing for Intermittent and Poor Connections at Diagnostic Aids under Diagrams.

TEST DESCRIPTION
The steps below refer to the test steps in the diagnostic table.
8. Test for battery voltage (B+) in the supply circuit of the Sunroof Control Module. If voltage is not present, go to the RAP Inoperative table.
