Wipers worked one turn then stopped

The wipers lost their index... Turn the car on, turn the wipers on, shut the car off when the wipers reach their full down position. Turn the wipers off, the. Turn the car back on. This should relearn the wiper index.

The windshield wiper circuit has an circuit breaker in it, under heavy load this breaker trips to protect the wiper motor, when the motor cools, the breaker resets automatically restoring proper wiper action.

First you must diagnose why windscreen wipers going slow and/or stopping.
In order to find out the cause of wipers stopping you can try follows: 1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!! 2. Disassemble the plastic covers from the bottom of the windscreen. 3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables. 4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encounter fault of the wipers running at Audi. 5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters. 6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation! 7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
Refit all in reverse order.

Please rate my response. Thanks!

wipers stop halfway up windscreen

Does the wiper motor run? If you can hear the wiper motor run, the wipers arms may have disconnected from the wiper motor,you will have to remove the wiper arms,and the plastic cover to access the wiper motor,and check for damaged parts.If your wiper motor does nothing at all, you probably blew a fuse do to the resistance on the arms,refer to your owners guide for fuse panel, and fuse locations. hope this helps

hi this sounds like the linkage has either snapped or has simply come off the ball joint if you can still hear your wiper motor running this will be it, they are a bit awkward to get to but normally a simple repair. lift your hood ( sorry ime from uk excues me for wrong use of parts lol) and look near windscreen area where the wipers are . look into the gaps vent gaps you will see the linkage put wipers on and see if there is any movment in there, if not then it will be that...hope this sorta helps

see if the transmission arms for the wiper motor are moving when the wiper motor is on. The bolts that hold the arms to the motor may be loose or stripped out from the heavy know. The threads for these bolts are thin and don't take much to strip.

If the wipers were buried under snow/ice or frozen to the windshield, you may have blown the red 10 amp fuse located in cavity 9 in the fuse block located on the bottom left side of the instrument panel near the parking brake pedal.
In order of easiest to check:
1) ensure wipers not frozen to windshield.
2) ensure wiper arms are not loose on the pivot stud,
3) check the red 10 amp fuse.
You stated that "you can hear the motor". Which motor do you hear? The engine or the wiper motor?
If you hear the wiper motor, then the fuse is alright. Try 1) and 2) above.

your wipers work off of a rocker arm from the motor this could be fixed in 1 hr just needs to be reattached
