Q: How to Replace a Sunroof Cable for the Rear Sunshade on Cadillac SRX?
A: You should start the sunroof sunshade cable assembly replacement by opening the rear sunshade and lowering the headliner for access. Begin by removing the center and rear vent windows followed by removing both the rear sunshade motor/actuator and the rear sunshade. Mark the rear track's position to the frame before you remove all screws from the rear track assembly. Then lower the rear track while disconnecting its extension from the track. First detach the rear extension before dislodging the sunshade drive tube from its track position. Pull the sunshade cable from the barrel end of the track while keeping it through the drive tube until you reach the motor/actuator compartment. Then detach the sunshade cable from the vehicle. Place the sunshade cable onto the drive tube and guide it through the tube into the motor/actuator compartment. Position the barrel end of the sunroof/sunshade cable in the rear track channel while making sure it fits correctly on the opposing track. Implement the rear track extension and drive tubes onto the rear track before aligning the rear track with previously marked sunroof frame positions. First tighten the rear track screws to 5 N.m (44 lb in) and then measure the cross-vehicle distances on each rear track. The installation order starts with the sunshade assembly followed by the rear sunroof/sunshade motor/actuator and ends with rear vent window installation alongside the center window panel. Complete installation by mounting the headliner while performing the sunshade programming protocol for the rear vent window.
