The winshield wipers on my 2002 montana are not moving. The motor works but wipers do not move. I can tighten the screw in the middle but there appears that there should be one ot two pins inserted vertically through the two or three plates. The top plate has a center hole for the hex screw and two other holes - one just off center and the second one on the outside edge. A second lower plate has a counter clockwise curved slot from the interior to the ouside edge. There is a bottom plate as well. A loose pin was found partially inserted into one of the top plate holes. The pin can be inserted all the way through the three plates - top outside hole, curved slot middle plate and the bottom plate, however, there is nothing to keep in place - seems to be missing a retaining clip. Do I need a new pin with retaining clip or do I need two pins? If I had labelled pictures of a correctly assembled unit it would be helpful. At this point I

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Sounds like you need a new winshield wiper motor,if you can hear the motor but the blades wont move try moving them by hand while the motor is going mybe you will get lucky

If the wiper on the passengers side is working normally and only the drivers side is not working.Then it is not the motor because there is only one motor and it works both sides.What you need to do is remove the drivers side wiper and clean the splines on the wiper transmission and reinstall the wiper and tighten it down.The hardest part is usually getting the wiper off.But if yours is not moving then it should come right off.All you need is a 13mmwrench or socket to remove the nut that holds the wiper on.You can do this yourself and it will cost nothing.The usual problem is they just come loose.Hope this helps.Good luck.

While wipers off in parked position, remove wiper arm and re-position arm to correct stowed position.
Re-tighten any wiper arm attachment nuts/screws etc.
Check wiper attachment arm for damage or cracks at the spigot mount. Replace if damaged.

You likely don't need a new motor. You just have to get your wipers repacked with grease.

Had the same problem on my '92 and 97. on the wiper motor there is a front cover held by a center screw... remove the cover there should be a small computer circuit board... disconect and replace... the cards are known to fail and a new replacement part, not a used one. they all fail on the older models.. new one has corrected the issue with the card... hope this works;;

Does the wiper still make noise like it is trying to go? If so open the cap where is attached and tighten the nut on the wiper. If does not make noise you will need a wiper motor.
