Windshield wiper not moving.motor works.wiper was iced up,turned them on and they started to move then popped.wiper motor works and wipers seem to move a little.

The wiring may be shorted or the motor went bad. Look for grounded wires at the motor Windshield Wiper Motor Replacement How to Troubleshoot Broken Windshield...

because thats when your motor went or the motor was repaced in the wrong postion

sounds like the wipers are stuck if you have to force them when disconnected from the motor, try lubricating all moving parts,

At the base of the wiper arm there is a plastic cap,pop this off ,underneath there is a nut that holds the arm in place ,if it gets loose the post will turn inside the blade.Just turn the wipers off and tighten the nuts with the blade in the parked position.

It could be a fuse or your wiper motor has locked up. Do you hear the motor kick on when you turn them on?

Sounds like the link rod has popped off or the wiper arm nuts need tightened. When the wipers freeze to the windshield and you start the wipers to clear the snow this will either strip out the wiper arms or pop the linkage rod off. Always pull the wipers away from the windshield before you start the wiper motor in cold weather to be sure they are not frozen to the windshield. Ok how to repair. Grab the wiper arms and see if they freely move in thier normal pattern with power off. Do they move independantly of each other ? If your lucky the nut holding the arms to the pivot just needs tightened. At the base of each arm is a black cover you have to pry up th see the nut. If not remove the wiper arms and inspect to see if they are stripped out. If they are stripped out bad enough you may have to replace them. If not then the linkage has popped off beneath the drainage grill. To see the link rods move look down thru the grill with the wiper motor running and the wiper arms off and you may see the rod flopping around. Now pry the plastic grills off, with the power off, left side first to get to the rod. Look to see if the plastic retainer in the end that fell off is still ok if so just line it up and give it a smack to pop it back on to the ball stud. If the shaft that is installed onto the motor is spinning but not moving the rod the motor must be replaced. Oopen hood and remove three bolts holding the motor to the firewall to remove it. Just reverse the process to reinstall. Thanks for asking at Fixya.com.

Could be anything but based on experience the probability points to the self cancelling switching in the motor gearbox.

at the base of the wiper arms pop the caps off turn on the wipers see if the safts are moving if they are tighten the nuts a little if that doesn't work you will have to replace the wiper arms i had the same ting happen on all three of my fords truck van and taurus

You broke the wiper transmission. Most of the time they are dealer only parts.

don't have to remove the dash- remove the plastic black cowl just under the wipers. The "pop" you heard is probably the clasp coming off the ball nut connected to the wiper motor. check the mounting plate for damage (usually they're good or need a little bending-needle nose pliers work best). Screw the two nuts back down after you reposition the unit. Turn on wipers to test connection, but make sure wipers are clear before testing. Replace cowl and you're back in business.
