Does anyone know how to change the rear wiper blade. Can i replace the whole arm or try to buy just the rubber blade? thanks for the help.

 

Most people just buy the rubber insert.

 

Remove the black plastic cover at the base of the wiper arm. It snaps off. Then the wiper arm can lock in outward position. . The plastic on removing you will hear a snap, not to worry, they are supposed to snap "off" and "ON". The refill are available at sewell at 3.20$.

 

Sorry to bump an old thread but...

You no longer have to go to the dealer to buy a rear wiper blade for the GX470. Trico just added a part number to their "Exact Fit Rear" line: 16-A. It was just introduced this month as a new part number to an existing line.

Someone above asked about installation...here is a video (watch xx-A)

 

No charge.
