How to Restore the Malfunctioning Sunroof Button on a Compass?

[McJake]

The method to restore the malfunctioning sunroof button on a Compass is: If there is an issue with the sunroof control button's mini-program, simply initialize the sunroof control button. The maintenance methods for a car sunroof are: 1. Regularly check the condition of the sunroof rails to ensure they are normal; 2. Reduce the frequency of sunroof usage; 3. Do not open the sunroof when the car is cold in winter; 4. Before the rainy season arrives, check the drainage status of the sunroof to ensure it is normal. Taking the 2021 Compass as an example, its body dimensions are: length 4424mm, width 1819mm, height 1635mm, wheelbase 2636mm, and curb weight 1430kg.

Oh my, my old Compass had the sunroof button act up last Sunday too! Don’t rush to spend money at the repair shop—here are a few DIY fixes. First, find a needle or toothpick and poke the small reset hole under the button. Hold it for 10 seconds to let the system reboot. If that doesn’t work, just disconnect the negative terminal of the battery for five minutes to reset the whole car’s electronics—this trick works wonders for glitchy devices. While you’re at it, clean out the dust buildup around the button; grime can cause malfunctions too. If it still doesn’t work, check if rainwater leakage caused a short circuit or if the connector behind the button is loose. Open the sunglasses compartment and see if you can reach the wiring harness connector—unplug and firmly reconnect it, listening for a click. The final resort is manual operation: open the sunglasses compartment, use a hex wrench to slowly turn the motor shaft (remember to peel back the dust cover first).

Last year, my car's sunroof button suddenly stopped responding, and I found it was due to dirty tracks triggering the anti-pinch function. First, slightly lift the sunroof to create a gap, then use a wet cloth wrapped around chopsticks to clean the sand and leaves on both sides of the tracks, especially around the drainage holes. After cleaning, spray window lubricant (avoid using engine oil) and then hold down the switch to attempt a reset. If the reset fails, you’ll need to reset the program: After ignition, hold the switch until the sunroof fully opens and then closes completely. Upon hearing a click, continue holding for 15 seconds. Pay attention to the motor sound during operation—if there’s a humming noise but the sunroof doesn’t move, it may indicate gear slippage. If there’s no sound at all, check the fuse. The manual indicates F36 is a 15A sunroof fuse located in the fuse box on the right side of the trunk.

Don't panic when buttons malfunction—it's likely a contact issue. Removing the button panel is surprisingly simple: pry open the reading light cover from the passenger side, remove two T20 screws, and you'll see the button assembly. Unplug the wiring harness and spray WD-40 on the gold fingers, then plug and unplug several times to remove oxidation. Pay special attention to testing the continuity of the No. 19 purple switch signal wire. If you have the tools, use a multimeter to measure the switch resistance—it should be close to 0 when the button is pressed. I've encountered cases where the sunroof module froze, requiring a five-minute power disconnect. The module is hidden in the headliner, and you'll need to remove the sun visor to access it. Be careful not to pull and break the ambient light wiring harness when handling it yourself. If all else fails, a trip to the dealership for a software reset costs just around a hundred bucks.

Just fixed the same issue with my car. First, check the sunroof's initial position: press and hold the close button for 30 seconds when it's fully closed to calibrate. The sunroof should jitter to indicate success. Then, test the anti-pinch function by placing a bottle of water on the window frame and pressing close—it should automatically retract if working properly. If calibration fails, it might be due to deformed rails or old weather stripping jamming the glass, which can falsely trigger the protection. For DIY repair, first buy a can of electronic contact cleaner, spray it into the button gaps, and press the button vigorously 20 times to remove dirt. Next, check if the 10A fuse in position 14 of the fuse box is blown. As a last resort, disconnect the module connector for half an hour to reset it—you can feel the module near the roof handle.

My 2013 Jeep Compass had this issue before. First, remove the dome light cover to inspect the wiring, and you'll likely find the connector loosened by the aftermarket dashcam. Reconnecting the plug didn't fix it, so I proceeded to test the switch voltage: disassemble the button and use a wire to bridge the green-white wire and brown wire - the sunroof should activate. If it works, the switch is faulty (replacement switch assemblies cost around 100 RMB on Taobao). If not, test the motor located beneath the center of the sun visor (remove two Torx screws for access). Connect a 12V power source directly to the motor terminals (blue wire positive, brown negative) - if the motor runs, there's a wiring issue. Common break points occur at the sharp bend in the left A-pillar wiring harness. Final reminder: Always check drainage holes after closing the roof - pour water at all four corners to confirm quick drainage. Clogged drains can fry the control module.
