How to Fix a Car Window

Power windows are great until they quit working. Here's how to fix one.

You will need

  • Rubber gloves
  • Safety goggles
  • Fuse
  • Panel removal tool
  • Screwdriver
  • Contact cement
  • Car manual with wiring diagrams (optional)
  • Voltmeter (optional)

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.

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.

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.

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.

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!
