i am having a problem with my rear wiper. it only cleans the window on the bottom half. for some reason the top half of the wiper blade is not making contact with the window. its a brand new blade too so i dont think that would be a problem. im thinking it may be a problem with the arm but im not sure. any suggestions?

 

Is the hatch window completely closed?
Turn the wiper on and watch it work. Pull the wiper arm out a bit and release. Observe if it is indeed the wiper arm. Could be a bad spring inside the arm.

 

yes the hatch window is closed. the wiper will not work if its open a little. ill try what you said and see if i can figure out what happend

 

Hey I have the same problem... just started checking the forums for that problem thought. It seems like it's one thing after another with theBlazer.I see you posted this a while back. Did you ever get it fixed? I havent really looked at the wiper in detail to see if I can figure it out myself. Thanks for any help!.
