Frequently Asked Questions
Will this bolt directly to my door frame without modification?
Yes — this is a direct OEM replacement. Remove the old unit, bolt the new assembly to the existing mounting points in your door, and connect the factory wiring harness. No drilling or cutting required.
Do I need to remove the entire door panel to install this?
You'll need to access the interior door panel to reach the motor and regulator mounting bolts. Most installs require removal of the window regulator cover panel, door handle assembly, and interior trim pieces — plan 1–2 hours with basic hand tools.
What's your return window if the motor fails after installation?
We stand behind every part we ship. Contact support with photos or a description of the failure within 30 days of purchase, and we'll work out a replacement or refund. Keep your original part and packaging.
