I have 03 Cadillac DeVille and my sunroof stopped working. Fully open when you push button to close you hear a click but nothing happens. What could be the problem.

Check the RAP fuse in the rear fuse box , this fuse powers the sunroof control module ! Fuse Block - Rear , Left rear of the passenger compartment, under the rear seat .
The sunroof module contains the logic for the opening and the closing of the sunroof. The sunroof motor assembly contains the reversible DC drive motor, the gear train, and the limit switch.
The sunroof module determines the sunroof motor direction based on inputs received from the overhead console sunroof switches. When the ignition switch is in the ON position or when retained accessory power (RAP) is active, voltage is applied to the sunroof module via the RAP relay. For a description and operation of the RAP system, refer to Retained Accessory Power (RAP) Description and Operation in Retained Accessory Power. The sunroof module controls the sunroof motor direction by changing the polarity of the applied voltage. The sunroof module remembers the sunroof position whenever the ignition switch is turned to the OFF position. The limit switch is used as an input to the sunroof module to indicate that the glass is fully closed, or in the comfort stop positions. The limit switch is grounded when the sunroof glass is in the fully closed or comfort stop positions, otherwise it is open.
The SLIDE CLOSE mode is initiated by moving and holding the sunroof slide switch (ROOF) forward. This applies a ground provided from the sunroof limit switch low reference circuit to the sunroof switch close vent signal input of the sunroof module. The sunroof module controls voltage to the control circuits of the sunroof motor. The sunroof motor will run until the limit switch contacts are closed. The closing of the limit switch will apply the sunroof limit switch low reference circuit to the sunroof limit switch soft stop signal circuit to the sunroof module, indicating the flush closed position has been reached. As the sunroof is approaching the close position the sunroof glass will force the wind deflector downward.
You need to have a factory scan tool hooked up an have it checked for DTC'S in the sunroof control module ! a code reader will not do this , a code reader will only check the engine codes for OBD 2 .
Important: The following must be completed before using the symptom tables.

1. Perform Diagnostic System Check - Power Sunroof in order to verify that all of the following are true:
?€¢
No DTCs are set.



?€¢
The control modules can communicate via the serial data link.


2. Review the system operation in order to familiarize yourself with the system functions. Refer to Sunroof Description and Operation

your better off taking to the dealer !

my sunroof is stuck oprn and the close button does not work

03 Jeep Liberty sunroof wont close. I have 4 sunroof buttons; Open, Close, Vent and ASC. Open and Vent buttons are working fine. Close button is not responding. ASC button is flashing red and green but does nothing when pushed. I have no way to get it closed

they run on a worm-gear as i remember plastic and i pulled the entire thing out and cleaned and greased it try pulling on it as you press the button is my best answer otherwise a project

Can't say for sure about this particular model, but most vehicles with sunroofs have a manual crank for situations like this. Generally it is located forward of the sunroof on the roof of the interior of the car, sometimes under a panel or interior light. This at least will get the roof closed until the problem can be fixed. It may also allow the sun roof to realign itself and help the electric crank to start working again.

most of the time on those sun roofs when you hear the clicking noise coming from the headliner when trying to open or close your sunroof and you have to help it move that clicking is the gear in the motor skipping ,I just fixed one on an infinity the other day that was doing the same thing ,the plastic gear gets worn down and will not grab any longer ,hope this helps!

If you hear the motor then you can almost certainly rule out electrical issues, it souonds more likely that the roof panel or drive mechanism is jammed or stuck, If the roof is closed then push up on the rear of the sunroof and see if it "pops up" a bit then while still pushing up hit the button to open.If it is anywhere in between open and closed try pushing it open or pulling it closed while you are pushing the button,if it moves inspect the tracks and lubricate

clean the runners on the sunroof watching out for trapped debris. try lubricating the runners with a fine lubricant with a clothe, make sure no debris caught in motor also.
