What to Do When the Power Window Button Gets Wet and Stops Working?
2 Answers
Solutions for a non-responsive power window button due to water ingress are as follows: Dry the water: Use a hair dryer to dry the power window button, then test if it functions normally. Excessive water in the window track: If there is too much water in the window track, it can increase resistance, causing the power window button to stop responding. Check the button: Remove the button switch and inspect the contacts for water stains or accumulation; dry them promptly and test the button again. Inspect the window regulator: Verify if the window regulator is functioning properly, as water damage to the regulator can also cause the power window to stop responding.
If the window button gets wet and stops working, based on my car repair experience, it's crucial to address it promptly to avoid further issues. The first step is to disconnect the negative battery terminal for a few minutes to prevent short circuits, fire, or electric shock hazards. Then, use a vacuum or paper towels to dry the surface moisture from the button, followed by a low-heat setting on a hair dryer for 10-15 minutes to help dry the interior—avoid high heat to prevent damaging components. Afterward, gently clean the connector with a toothpick to check for any debris. Once completely dry, reconnect the battery and test the button. If it still doesn’t work, the wiring might be corroded, requiring removal of the door panel to inspect the connectors or placing a moisture-absorbing pack near the button for a day or two. To prevent recurrence, avoid spilling liquids while driving and ensure windows are closed. If DIY fixes fail, visiting a professional shop for a button replacement is affordable.
