Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front left position before installation. This assembly uses bolt-on mounting and a plug-in electrical connection, so the door trim panel and related components must be removed to access the regulator. Confirm the glass is properly supported during service and inspect the window tracks, guides, and electrical connector condition before final assembly.
