How to change the rear wiper on a 2003 Pontiac Vibe

Hello,

1. After you have removed the old wiper blade make sure to remove any adapter left behind on the actual wiper arm as the new blade should come with a multi use adapter.
2. It should just be a bare metal rounded hook bar now.
3. Now if there is not adapter on the new wiper blade then put the one provided on. Often times the wiper blade comes with this adapter already on the wiper blade.
4. Pull the wiper arm out a bit and set the new blade under the open section of the wiper arm.
5. That adapter will have a little play to it.
6. Push it up a bit so it fits in the slot on the wiper arm and pull up on the wiper blade and the blade should "click" into place.

Do the same for the other side and your good to go. I also recommend Raine X for your windshield. My experience as a mechanic and a storm chaser has proven Rain X to be invaluable in severe weather.
Regards, Tony

Remove the wiper arm. Switch on the wipers for a 15 seconds or so then switch them off and allow the wiper motor to reach the "Park" position. Re-fit the wiper arm/blade so the blade sits an inch or 2 from the lower edge of the windscreen. Pour some water on the screen or use the screenwashers and try the wipers to see if they still travel beyond the edge of the screen. Small adjustments can be made by lowering the arm towards the bottom edge of the screen by a couple of splines on the shaft. If it still travels beyond the edge of the screen then you may need a replacement linkage as it could be worn. You may be able to buy the linkage only and use your existing motor-I know this is possible with the Sharan but not sure on your model/year.

I would try Walmart or Autozone or Oreillys. If I remember correctly I had a 1988 Taurus and there was a change in the mounting pin size on the tip of the wiper mount. Some of the replacement wiper blades had adapters included with the wiper blade.

It may be necessary to buy the wiper arm that fits into the drive posts at the base of the windshield. The spring tension would be restored and you could eliminate the current mounting problem.

there are little tabs at the end of the arm where it attaches to the wiper trans. if you bend the arms up at the hinge and swing those tabs out the arms will stay up (a small screw driver can be used to move the tabs if they are stuck. A 1/8 screwdriver is a good choice, $4 at sears). once those tabs are out and the arms are holding themselves up just pull. you may need to rock them back and forth a bit but they should just pull off.
