The shaft from the motor to the wiper actuating arms is possibly stripped or disconnected. You will need to trace the wipers back to the wiper motor to find the problem. As mentioned follow the linkages back to the motor as they sometimes pop out of their cups.
If the motor is turning, but the wipers are not moving, then you have a broken or disconnected linkage.
You have to diagnose it first. With key on and wiper switch on, listen carefully, if you do not hear an electric motor running check the fuse. If the fuse is good and the wiper motor is receiving power and ground, the wiper motor assembly is probably bad. If you hear a motor running but nothing is moving, the wiper transmission assembly is stripped or the linkage is loose and came apart.
Sounds like broken linkage maybe. I think... you need to pull the air vent intake grill underneath your windshield wipers blades to get to it.
The resistance of the ice was greater than the strength of your wiper linkage or AKA wiper transmission. IT is probably broke, but may just be disconnected.
Most likely you will need to replace the wiper motor. If you can hear the motor when you turn the wipers on, then you will need to replace the wiper transmission. The wiper transmission is a link that attaches to the motor and the wiper arm. Both are located on the firewall usually under the cowl panel. (the panel between the hood and the windshield)
it is your starter motor sticking, or could be your alternator but i think it is defo your starte motor.
First thing to do-- check if the wiper is attached to the motor at all. My Suburban loosened both bolts and thus, no connection means no movement. The bolt is found by lifting the hood and checking the bottom of the arm. If there is no nut (my problem- luckily the bolt was in the engine, visible) or a loose nut, (find) tighten it and see if that works.
You probably have a break in the linkage. The motor turns the linkage that makes the wipers move. The linkage is connected by plastic caps over a ball joint. These can separate. You can buy new generic plastic caps to try and replace from parts stores. It works sometimes. New linkage from GM isa one part and replaces all linkage and joints. Close to $200.
Do you hear the motor running? If there is no sound, the motor has probably burnt out and needs to be replaced. If you do hear the motor running, you've probably stripped a gear. They can sometimes be replaced, but it might be more cost effective to replace it.
window powered down but will not go up, I can hear the motor running
if you can hear the motor its more than likely the linkage has popped off (normally a plastic clip allowing arm to move on the motor) its under the bonnet attached to the wiper motor, presuming its not dammaged you should be able to snap the conector back together, another common problem with wiper arms is the nut come loose on the thread holding the arm to the linkage (normally when wipers put on to clear snow off the screen as no recent snow fall should not be this but is still possable)
Had a problem the same. One of the pivots where the wiper arm attaches in the drive assembly attached to the wiper motor had ceased. Used assembly, motor and transmission arms $125
