There is no real adjustment to this rear wiper arm/blade. The arm typically gets pulled from car washes. I do have a permanent fix for this though. You'll need to pull the entire arm off the splined motor shaft. But first, remove the plastic end cap by slightly spreading the sides and slipping it off the end of the arm. Loosen the nut and with a small pulley, remove the whole arm from the splined motor shaft. Dissasemble the entire arm by carefully bending the blade arm away from the arm itself. It will come off, just don't force it too much. Turn the arm over and remove the spring between the long and short arm sections. Carefull, this spring is tough and you'll need to use some force. The repair consists of two steps. First, bend the spring ever so slightly to shorten the overall length of the spring. Just slightly. This will put a little more downforce pressure on the arm to the glass. Now for the big part. Notice how the arm works without the spring. The arm pivots in the center against the small arm section. There is a flange that stops the arms movement against the spring's force. That stop flange needs to be shaved so that the arm closes further (1/4" slightly yields decreased angle to the window). This shaving off of 1/4" from the stop, will make the arm apply greater pressure/travel to the window itself thereby pressing the wiper blade against the window nicely. Reassemble and reistall the arm. Problem should be corrected forever. I've done it to mine and it works great now, better than new. Puts nice down pressure against the window to wipe nicely, and returns nicely to the rest position. Good luck......let me know how you make out.....
