The window regulator manages the window’s ability to roll down or up. It would be best if you avoided any trouble in your journey; it is better to check whether the window regulator shows signs of wear and how you can replace window regulator and motor.
Reasons for window regulator failure and how to replace window regulator and motor
Over time, prolonged use can cause the window regulator to overheat, and gradually it fails to provide better functioning. A window’s connection to a regulator may get broken in subfreezing conditions.
Change of window regulator:
- By contrasting them, please verify that the new and old window regulators have the same design. Move the old window motor.
- The mounting fasteners for the motor should be torqued. Put the regulator component through the door’s aperture.
- Have a helper hold this window in position momentarily. After that, take off the fabric tape and the wooden block. Onto the regulator’s guidance section, lower the window.
- The regulator-to-guide installation bolts should be torqued to the manufacturer’s specifications using a torque wrench.
- Reconnect the electrical connector for the power window motor and tighten the mounting nuts.
- Replace the power windows switch component momentarily. When finished, unplug the switch assembly and take it out.
- Put the water deflector back into place.
Change of window motor
- The motor will be largely hidden because it will be located behind of regulator component. An electrical socket is attached to the cable drive upfront. Remember that your car’s setup will change based on the door and model year.
- Unplug the motor.
- Take out the four Torx screws fastening the white gearbox to the metal housing of the motor.
- Take the motor’s metal case off.
- With the circuit panel, remove the motor shaft. The gearbox will experience stress when the window is closed. To remove tension, manually rotate the motor shaft 3–4 revolutions counterclockwise.
- Find the white plastic spacer if it hasn’t already fallen free from the motor shaft. An inspection mirror could be useful. Use tweezers to remove the spacer.
- Try out the spring seats with a tiny screwdriver after removing the circuit panel from the motor shaft. Eliminate the springs. Reposition contact points into their slots using tweezers. Pull the panel away from the shaft.
- Examine and clean the copper area of the shaft. Clean the motor shaft’s copper contact region with steel wool. Clean the circuit panel’s contact points, and you can install a new motor if the previous one is damaged.
- Slide the circuit panel up to the contact area over the shaft. While placing contact springs and seats, hold the circuit panel firmly in place. Slide the shaft with the panel into the metal casing until the panel is flush with the case.
- Reinstall the plastic spacer in its gearbox place. Verify its positioning with an examination mirror.
- Reinstall the motor and circuit panel in the gearbox. Align the motor shaft with the gearbox as closely as possible to prevent disturbing the spacer. Insert firmly and use screws to secure.
- Reconnect the motor plug and check how the window works.
- Reattach the door panel properly.
