How The Part Works
The rear wiper mechanism contains the gear train, spindle bearing and a microswitch that detects the park position. When the motor turns, the mechanism converts rotary motion to sweep the rear wiper arm across the glass and return it to the parked position. The microswitch ensures accurate park signalling so the arm stops and rests correctly when the system is switched off.

Recommendation: Use Appropriate Trim Tools To Avoid Damaging Interior Clips. After Installation, Cycle The Wiper To Confirm Proper Park Position And Smooth Operation.
Why This Part Most Often Fails
Rear wiper mechanisms typically fail due to water ingress and corrosion, which attack metal components and electrical contacts. Plastic gear teeth and linkages may wear or break with age, while bearings can seize from contamination. The microswitch or motor connections can also deteriorate, causing intermittent operation or loss of accurate park detection. Frequent use in harsh climates or long periods of inactivity accelerates wear.
