[:o]Hello has anybody out there replaced the rear window wiper blade with a factory windshield wiper blade? I bought a factory blade off of E-Bay but can't see how the old blade comes off, the owner's book says there is a tab to lift to get the blade off my 06 HHR LT has no tab on the wiper blade, thought I would ask before I break the plastic blade trying to get it off!![:-]
