One by one I've been working out the small bugs in the 04 expedition I just picked up and have decided to tackle the inoperable rear windshield wiper. The motor itself functions properly when the glass is open but when closed all I hear is a click, I tried to move the arm myself with the glass open and was successful but it took a considerable amount of force. Has anyone else had any issues with this ?
If so, I'm hoping to hear there are other solutions other than complete replacement of the arm and mechanism. I already squirted some wd-40 in there and saw little improvement.

Bad weather seal perhaps? If the motor attempts to move there's tension somewhere along the line. It won't hurt to take the inner hatch panel off, carefully peel back the weather barrier and have a look as the assembly. If you do this, it'd be good to lube the door lock mechanism as well. You can also attempt to Google the problem, or, check online for a free copy of the factory service manual (FSM). Keep us posted.

Well after a bit of investigation i found some info on edmunds, it seems that some people have had success tearing down and relubricating the arm. Its a real pain getting the arm apart but Im ok with that!

I fixed the problem. There are two nuts on the back of the lift glass and, of course, a couple on the arm itself that will need to be taken off to remove the problem cylinder. Once it is off of the lift glass there is a snap ring just under where the wiper arm was bolted on, that must be removed in order to get the moving part hammered out... The pic posted shows the snap ring, I just went caveman with the plate i pulled off of the lift glass and hammered that wiper arm bolt on the concrete to get it started and then finished the job with a punch and a hammer. After that wiper arm bolt is out just clean it, grease it, and put everything back together and its good to go.

Sorry I just have the one pic by the time I thought about it, it was too late.....
