If drivers wiper arm will not move by motor operation and can be easily moved by hand ( with wiper on or off ) suspect disconnected/broken linkage. If wiper arm will not move by motor and takes effort ( With wiper on ) by hand... suspect seized wiper pivot
You must remove the wiper arm to make sure the serrations on both the arm and where it mounts to are not damaged. Turn on the wipers and see if the nub that the wiper arm mounts to is moving.
If it isn't, there is a mechanism called the Wiper Transmission. It is located in the cowl at the bottom of the windshield. The device has a number of arms. The arm that connects the right side to the transmission is off. This is usually the fault of a small round plastic piece at the end of the arm. Simply putting it back on is nit recommended because it will probably fall off again. This plastic piece is attainable at most good auto parts places.
you need to check to make sure the "arm" is moving , some gm vehilce have a sealed wiper unit, but the alero should still have arms. turn wipers on and look down at the cowl vent and see if it appears to move. if it is the mounting post for the arm on the passenger side has PROBABLY stripped out the soft lead mount at the bottom of the wiper arm. make sure the wipers are "parked", then carefully try to wiggle the pass side back and forth (its normal motion...). if it moves you will need to pop the arm off(super careful here..) and the post that looks smooth must be cleaned out with a fine pick or equilalent, the post accually has splines all around to engage the wiper arm. put on the new arm.. presto.... wipers.
When you tried to move the wiper with the ice it probably broke an inner componette and connecting rodes from motor. You'll haft to inspect the rodes and motor to know what damage is done but it you can move the wiper easily by hand it's definitly broke. If it is real hard and dont want to move it might be jammed and you might be able to move it alittle to move it back into place.
Your wiper transmission is bad or disconnected. The part with the arms that are moving under the windshield cowling is called a wiper transmission. The main connection to these arms is a pin on the wiper motor which has a clip. The cowling is the area directly under the windshield. You may be able to unscrew the cowling and remove it to access the shaft arms on the wiper transmission.
You may need to remove the wiper motor to get at the clip on the motor. Then each arm is mounted to the base of the cowling. These are the stubs which the wiper arms attach to. Usually the shaft arms are a permanent part of the piece which fits over the motor. But is worth a look at what broke to see how it used to be attached.
If the transmission arms were in a pressed-on fitting, you will either have to replace it or improvise a new connection. The connection will have to be secure, yet not drag on the wiper, and not make noise. That kinda makes a new part or Salvage yard part your options.
By going to a Salvage yard first, you will learn how the part comes off. Gather extra screws for the ones you may drop reinstalling the part. And if you break something on the Salvage car, you will know better when you work on yours.
In view of the answer from jchaffcom I feel that if there is a Hex on the end of the Wiper Arm the Hex Nut needs Tightened. I have a 2004 Silverado and this is what happened to it. Simply tightening the Nut solved my problem. Try it and get back to me with the results whether good or bad.
