Function And Symptoms
The Rear Wiper Motor Converts Electrical Input Into Rotational Force To Move The Rear Wiper Arm Across The Glass. Common Symptoms Of A Faulty Motor Include No Movement When Switched On, Intermittent Operation, Excessive Noise Or Sluggish Movement. Other Signs May Be A Stalled Or Frozen Wiper Arm, Burnt Electrical Smell Or Blown Fuse When Attempting To Operate The Wiper.
Why This Part Fails
Failure Usually Results From Long-Term Water Ingress Or Corrosion, Worn Brushes Or Commutator Inside The Motor, Stripped Or Damaged Worm Gear Teeth, Or Seized Linkage Due To Contaminants. Rear Motors Are Exposed To Road Spray And Moisture, Which Over Time Degrades Seals And Electrical Contacts.
Replacement And Installation Recommendations
General Replacement Steps: Remove The Rear Wiper Arm, Detach The Tailgate Trim To Access The Motor And Linkage, Disconnect The Electrical Connector, Unscrew The Motor Mounting Bolts, Replace The Motor, Reconnect The Connector And Reassemble. Before Final Reassembly, Test The Motor Operation And Park Position By Activating The Wiper Switch.
Practical Tips: Mark The Wiper Park Position Before Removal To Ensure Correct Reinstallation. Support The Tailgate Trim Carefully To Avoid Breaking Clips. Inspect And Clean The Connector Pins; Replace Any Damaged Seals Or Gaskets To Minimize Future Water Ingress. Check Relevant Fuses And Wiring If Motor Still Does Not Operate.
Recommended Maintenance And Expected Lifetime
Lifetime Depends On Usage And Environmental Exposure; Motors Often Last Several Years But Can Fail Earlier If Exposed Frequently To Moisture Or Mechanical Overload. Regular Inspection Of The Tailgate Seal And Linkage, And Prompt Replacement Of A Worn Wiper Arm, Extends Service Life.
