Warning Be careful not to smash fingers in the window gears, and wear rubber gloves and safety goggles for protection when disassembling and repairing a car window. Step 1: Replace blown fuse If more than one window is on the fritz, try replacing the fuse first. Otherwise, leave the fuse disconnected for safety while you inspect the window's inner workings. Tip If you hear the motor trying to work when you press the up or down window controls, it's probably not a blown fuse. Step 2: Remove door panels Use a panel removal tool to pry off the panels on the inside of the car door and pull back the coverings to gain access to the mechanics inside. Use a screwdriver to remove any screws needed to get the coverings off. Tip Make a note of where to put the screws back later. Step 3: Check for jam Look at the gears inside to see if a jammed cable may be keeping your window off track so that it is stuck down or up. If so, set it back on track. Tip Consult electrical wiring diagrams for your car in the manual to learn how the window functions. Step 4: Follow the wiring Follow the wiring to search for any corroded connectors or switches that may be keeping your window's motor from working, and replace any bad ones. Tip Use a voltmeter to test the voltage at each point along the wiring. Step 5: Fix bad gaskets Replace or repair the seal on any loose or faulty gaskets if the window won't roll up or sticks in some places. Step 6: Consider a new motor If your window needs a new motor, decide whether you can replace it yourself, which will depend on your mechanical experience, available tools, and the type of car. Step 7: Reassemble Reassemble the window and door parts, using contact cement to hold the plastic insulating layer in place if necessary. Enjoy your working windows! Did You Know? Windshields were first added to vehicles in 1904. If the windshield became dirty or obstructed the view of the driver, it could be split in two, allowing the debris to fall off the top half of the glass.
