Through the Viewfinderthoughts of a photographer

Saturn Ion wiper mechanisms are prone to failure when the plastic casting in the wiper mechanism cracks. Signs of failure are apparent when your wiper blade suddenly becomes “floppy” and overshooting the window when it wipes. If you grasp the wiper blade down by it’s base (where it goes into the car) it should have very little play, if it wobbles around, chances are that the plastic mechanism has broken and you need to replace the mechanism.

For about $90 you can order a new replacement part that’s all metal from www.autopartsdirecttoyou.com Their website also has a very good installation article  http://www.autopartsdirecttoyou.info/?p=55

Start by removing the black plugs covering the nuts at the base of each wiper arm. Next, you have to remove the wiper arm nuts. Getting the wiper arms off is the most difficult and frustrating part. After you remove the nut, you’ll find that the wiper blade arm is pressed onto the tapered splines of the wiper mechanism. You’ll probably have to use a mini-hub puller to free up the blade arm. Before you do this, put the nut back on the wiper arm shaft loosely,  this will protect the threads from the hub puller. Be very careful, too much pressure from the hub puller could crack the wiper blade arm! Slowly adjust the hub puller, applying tension. Gently tap the top of the hub puller and at some point the wiper blade arm should pop loose! Using some Liquid Wrench will also help.

After the wiper arms are removed, keep them separated (the passenger side has the shorter wiper blade). Next, remove the plastic cowl covering the wiper mechanism.  There’s two push-pin fasteners (one on each outer end of the cowl) and two small hex screws (see photo). After these are off, disconnect the wiper washer hose and prop the cowl back so you can work on the mechanism.

Now you can reach in to remove the three large bolts holding the wiper mechanism, then slide it out so you can do the replacement.  If you’re careful, you can do all of this without unplugging the wiper motor (it’s very hard to unplug). It’s important at this point, that you carefully duplicate the position of the replacement arm mechanism with that of the one you’re removing. The position of the short bar that is bolted to the wiper motor is very important. If you don’t match it closely the mechanism won’t function correctly.

After the new mechanism is back together, replace the two wiper blade arms. Don’t tighten the wiper arm nuts fully, just enough to hold the arm to the mechanism for a test (you may have to remove and reposition them if they’re just not right). Run a test and after you’ve confirmed that the blades are in the correct position, tighten down the wiper arm nuts and replace the cover plugs.

This should be a good long term fix for this Saturn wiper problem since the replacement mechanism is all metal!
