I guess I tore the rubber on my rear wiper when it got frozen the the back window. DUH!
Looking at it, I can't figure out how to remove either just the rubber part or the whole wiper blade.

Can anybody help?

Geezer

 

Simply mix 1/3 part water and 2/3 part isopropyl or rubbing alcohol.

Pour the solution into a spray bottle. Spray on the window. It will unfreeze the rubber blade.

 

REMOVE REAR WIPER BLADE ASSEMBLY
(a)
Open the rear wiper arm head cap.

(b)
Raise the wiper blade to the position where the claw detaches with a ''click'' sound.

NOTICE:
Be careful not to damage the claw.

(c)
Pull the wiper blade straight toward the left side of the vehicle to remove it from the wiper arm.

NOTICE:
Do not fold the wiper arm with the wiper blade removed. The arm tip may damage the back door glass surface.

REMOVE REAR WIPER RUBBER
(a)
Lift and pull the end of the wiper rubber protruding from the blade stopper

NOTICE:
Do not forcibly pull out the wiper rubber. The backing plates will be deformed or the blade claws will be damaged.

HINT
Lightly pushing the rubber between the ends and middle will allow it to be removed more easily.
