How are Sunroof Switch issues diagnosed?
When the sunroof will not do one or more functions on demand, the switch will likely be tested first. The switch can be diagnosed as faulty simply by testing for continuity across the switch when the switch is cycled through all of its possible settings. If pressing the switch does not create a continuous circuit,the switch will be proven failed.
How are Sunroof Switches replaced?
Removal of the sunroof switch will likely require disassembly of the overhead console, removing the switch from the cover panel, disconnecting an electrical connector, and installing the new switch in reverse order. Some models will have the switch for the sunroof located on the instrument panel, in which case the switch may be removed without further disassembly, or the switch will require removing a larger access panel. In most cases it will be necessary to clean the electrical connector before reinstallation due to the high possibility of light to moderate water damage.
RepairPal Recommendations for Sunroof Switch issues
Checking your fuses first is always recommended when it comes to electronics. All too often an electrical component is replaced only to find it still does not function. This is because without a good fuse, the system will not receive power.
What to look out for when dealing with Sunroof Switch issues
The trim panels, switches, lights, and other accessories mounted near the sunroof switches on the overhead console are typically brittle after only a few years. This is the hottest place in a vehicle, and water that may enter the vehicle will assist in weakening the plastic trim pieces and accessories. Great car should be taken to slowly remove these components to prevent their destruction.
