Re: wiper arms dont move
There is a plastic little cup that fits into the arm and swing arm. it is the little metal piece that connects the wiper arms together. they click into place and hold the arm to the swing arm. that is probably why you have play and they arn't working.

The part that is attached to the wiper motor is in the wrong location. Remove the nut or bolt that attached the wiper transmission to the motor and remove the short arm from the wiper motor. Turn the wiper motor on and then off. wait until it stops moving. Set the wiper arms to the correct "home" position. Reattach the wiper transmission arm to the wiper motor.
It Sounds Like, Either The Arms Are Loose ,If You Can Hear Something Moving Behind The Dash, Or The Linkages Are Seized ,If The Motor Just Hums No Movement Heard,In Which Case Try Spraying Q 20 On The Linkage And Try Moving The Wiper Arms By Hand To Get It Going Again, If Not The Motor May Just Be Burn;t Out.
You know it sounds like a break in the linkage as the wiper motor will not usually let you freely move the wiper arms yourself. Generally there is an arm attached to the motor which in going around and around makes a side to side action in the wiper linkage. Without any more info I would suspect a failure in the ball joint connection between the wiper motor arm and the linkage. On a car that old most likely you should look around for a replacement used linkage on eBay or Craigslist. Once obtained, get yourself a repair manual or search on youtube for a video on how to remove and replace the linkage. there are many folks selling repair manuals on CD for about 10 bucks on eBay.
The rear wiper on the uplander is a common BOSCH unit and is very prone to one very small but very easy ( and CHEAP to fix ) problem. The shaft that goes through the glass on the rear hatch needs to have new grease.Thats it......If you think you need a new wiper motor try this.......take off your old wiper motor and remove the star drive screws that hold this thing together.Now pull this thing appart. Dont be afaid to do this remember you think that you are going to buy a new one anyway right. Inside you will see the electric motor with a worm gear thar turns a big yellow(or white) plastic wheel.sitting on top of that is a funky metal linkage that is connected to the BOTTOM of the shaft.On the TOP end of the shaft you will need to remove the small plastic ring and under that the small rubber o-ring. Now you need to pull the shaft and the linkage out of the unit. They should just pull out with no effort BUT you will find that they are stuck because all the grease has gone hard around the shaft stopping it from moving.Use a little penitrating oil around the shaft and work at it and it will come out. Now use a little break cleaner to clean the shaft and linkage ,apply new grease and put the thing back together again. PROBLEM SOLVED......try it .....trust me you dont need a new motor :-) If you really want to be lazy you dont even have to take the car apart just unbolt the rear wiper arm and remove thearm fron the car then clean the end of the shaft andunder all that dirt you will see the small plastic ring and under that the small o-ring .....remove both of these.now spray some penitrating oil down the shaft.give it a little timeand spray some more.try the rear wiper,if your lucky it will start to turn.put it all back together again.
Flip the caps up from bottom of wiper arm to expose where they attach to pivots. There should be a nut holding them on, try snugging that nut up a bit & see what happens. if it helps, remove the nuts, pry the arms off, and clean inside where spline etc., is and re-attach arms in proper(same) spot and tighten nuts again, but be careful not to tighten too much & snap the stud.
Probably stripped the little splines where wiper arm attaches to pivot. Flip the cover up where arm attaches to pivot, and tighten nuts on there, but be careful not to go too far, its not hard to snap the pivot stud if you tighten too much. make sure wipers are off, in park position, and move arms to where they should be, then tighten. See if you still get loud noise after. If you do, somethings wrong under cowl, in the linkages or motor. You may be able to see something with flashlight or troublelight.
