Use a multi-meter to make sure that the motor is getting the correct voltage. Attach the probes of your multi-meter to the motor’s plug and toggle the switch up and down. Make note of the voltage in both directions. Your owner’s manual should list the specific voltage required. Ensure that the window moves freely during this test. There should be no slow spots or blockages. Unplug the motor. If you the motor is getting the proper voltage but not functioning properly, you likely need to replace it. Start by unplugging the wiring connectors from the motor.
Locate a replacement fuse. It must be the rated for the same amperage as the original fuse that operated the window mechanism. The amp rating should be printed on the fuse, and it should also be listed in your owner’s manual. Do not use a fuse with a higher amp rating, as this may lead damaging the electrical components of your vehicle. Push the new fuse straight down into the cradle. The fuse must be "set". This means that it does not move or wobble. Turn your car key to the "on" position. This provides power to your windows and allows you to test them. You need not start your car. Test your windows. Confirm that they go up and down without restriction.
