Installation Recommendations

• Perform A Functional Test Of The New Motor Before Refitting The Door Trim To Save Time If Adjustment Is Needed.
• Use A Non-Corrosive Electrical Contact Cleaner On Connectors And Apply A Small Amount Of Dielectric Grease To Prevent Moisture Ingress.
• Support The Glass Securely During Work To Avoid Chipping Or Breakage.
• Check Regulator Condition At The Same Time; Replace Worn Regulator Components To Prevent Premature Motor Failure.

Most Common Failure Reasons

• Wear Of Carbon Brushes And Commutator Due To Long Service Life.
• Water Ingress And Corrosion From Damaged Door Seals Or Vapor Barrier.
