Q & A

What are the typical symptoms of a faulty window regulator motor?

Common symptoms include grinding noises, slow movement of the window, or the window failing to move at all.

Why is it important to diagnose the issue before replacing the window regulator motor?

Diagnosing the issue helps ensure that the motor is the actual cause of the problem, preventing unnecessary replacement of parts and saving money.

How can you check if the window regulator motor is faulty?

You should check the power window fuse, inspect the window switch, and test the window's electrical wiring for issues like shorts or loose connections.

What tools are required for replacing the window regulator motor?

You'll need a drill, drill bits, screwdrivers, pliers, a bungee cord to hold the door open, a tray for fasteners, and the new motor.

How do you safely remove the door panel to access the window motor?

Start by removing screws from the door panel, including those hidden under the armrest or handles. Use a plastic trim tool to carefully detach the panel from the door without damaging clips.

What should you do if the moisture barrier doesn't stick after removal?

You can replace the moisture barrier’s rubber strip, which might have lost its adhesive quality, by buying a new one and cutting it to fit the door.

Why is it important to keep track of screws and fasteners during the disassembly process?

Keeping track of the screws and fasteners ensures you can easily reassemble the door panel and other components without missing any parts, preventing damage or loose installations.

What is the correct method for drilling out the rivets holding the window motor in place?

Use a drill with the correct-sized bit to carefully drill out the rivets. Ensure you're only removing the rivet and not damaging surrounding components.

What should you do if the window binds after replacing the regulator motor?

If the window binds, apply dry lubricant to the tracks. This lubricant won’t attract dust like silicone and will help keep the window moving smoothly.

What are the cost savings of replacing only the motor instead of the entire window regulator assembly?

Replacing just the motor can cost around $50, whereas replacing the entire regulator assembly can cost up to $450, saving you a significant amount of money.
