Condition

Remove the damaged rear wiper arm/blade assembly. Refer to Rear Window Wiper Blade Replacement in SI.
Remove the old rear wiper arm park ramp. Refer to Wiper Park Ramp Replacement in SI.
Clean any residue left behind from the lift gate wiper arm ramp area.
Install the updated rear wiper arm park ramp.
Install the new rear wiper arm and blade assembly against the updated wiper arm park ramp.
Verify proper operation of rear wiper system.
