The driver side wiper arm works as it normally should, but the passenger side wiper arm will not rotate. The passenger side wiper arm stopped working after it encountered some resistance from about 1 inch of snow that had accumulated on the windshield over night. The driver side wiper pushed the snow off the windshield no problem, but the passenger side wiper got stuck half way, went back down to the rest position and now it will not work at all.
Yes. Here's how that works.
In front of the windshield is a pocket or channel that houses the wiper assembly.
The assembly consists of the wiper motor, the linkage, and the "transmissions". ( 2 ).
The motor is secured with screws, and has an electrical plug to obtain current to work.
The motor has a crank that either goes around and around, or back and forth, pushing and / or pulling the arms which are hooked to the "transmissions".
The transmission is nothing more that a crank that converts the back and forth movement to the wiper arms that hold the blades that you can see.
The passenger's side arm has become disconnected from the motor or the transmission.
Sometimes, it simply needs to be hooked back up, other times, it will need replacement.
Some cars require the removal of the hood to get to the wiper stuff, other cars have a removable panel with louvres that will come off.
Be Blessed.
Sounds like the connecting rod between both wiper arms either broke or one of the keepers popped off under the connector for that arm..since the wiper system IS NOT designed to wisk snow off the window once accumulated, this can an does happen.. even seen motors get burned out doing this..cleaning the window first will save this issue and the equiptment. need to acess this arm<take off the vented peice below the windshield and everything should be visible there..repost findings

Take off both of the wiper arms and try to use wipers if they are moving you didn't install the arms correctly. If thats the case with the arms off and the wipers running turn them off with the wiper switch and wait for them to "park", then tun off the ignition and reinstall the arms in their proper location. Also when the linkage falls off you should replace it with a new one. It is a ball and socket fitting and when it fails it spreads the plastic socket and loosens it up. It is also reccommended when you are inside there you should always replace the linkages in pairs and also check the pivots (the knurled studs that the wiper arms bolt to) for play and if necessary replace these as well. Good luck.

I just solved this problem last night with my '05 Impala, and ultimately the solution was what newton5083 stated above. Yet, it may also be this (I found it online somewhere):
You have bent or broken the "park tab" on the windshield wiper motor bracket. The correct way to fix this is to remove the wiper arms, wiper linkage and wiper motor from the wiper motor bracket, and install a new bracket.
I just bent the tab back into place a couple times for our daughters 2005 Impala but it kept getting bent down again when they didn't take the time to make sure the wipers were not frozen to the windshield, or tried running the wipers to remove heavy snow on the windshield. So yesterday I fabricated a small piece of metal and bolted that to the bracket in the same place the tab stop was.
If someone wants to access this bracket and tab-
1. Use a ½ inch or 13mm socket & ratchet or wrench to remove nuts on wiper arms.
2. They may make a special tool to remove the arms, I used a screwdriver and hammer to tap bottom of the arm to wedge them apart from the spindle.
3. Two small button-looking clips hold the drivers side cowl cover in place under the windshield. These are two-piece clips, pry up the center, than the outer piece.
4. Unclip the washer hose from cowl cover, than pull out plastic cover.
5. There is a smaller plastic cover with on plastic button head holding that cover in place. Gently pry under that clip to remove that cover.
6. Now you can see the wiper trans and bracket. You should see a small tab on that bracket that looks pushed down and bent or possible a square small hole with some torn off metal where the tab broke off.
7. Remove small plastic cover over the wiper transmission and you can see a small spring-loaded arm underneath the wiper transmission assembly.
8. You need to find something to pry that tab back up so when the wipers are running that spring loaded little arm just snaps past the tab running clockwise. It's when you shut off the wipers that the wiper transmission assembly reverses rotation counter clockwise and the small spring loaded arm underneath hits that tab stop, than the wipers will go all the way down and shut off as they should.
Once that tab stop gets bent out of the way the little spring loaded arm has nothing to stop the wiper transmission assembly so it keeps traveling counter clockwise until some other stop shuts the wipers off straight up on the windshield.
There is a revised bracket part # which is supposed to be more durable, GM part #12368639. Here is a copy of the TSB which points out this problem:

yes the wipers pull off and you need to get the linkage from the dealer the parts just snap on
SOURCE: The windshield wiper arm on the passenger side
Either the second arm on the motor has come off. Or the arm splines are stripped out. The second arm connecting snap has probly come off or the clip may have broken. you can usually see the arms move inside the cowel just in front of the windshield through the holes
