This is typical problem when AC Compressor starts to lock up and first makes a noise. then on overheating locks up and will stall the engine until something breaks either in the clutch or belt and it is free again to start engine. Thoroughly check you AC with/without belt and see if it rotates freely.

The easiest way to find an electrical draw is to remove the negative battery cable and put a test light in between the battery post and the cable. If a draw is present the light will light bright, a dim light is normal. You can now remove fuses until you find the circuit that has a short. You should start at the alternator, it is very common that a diode will short out inside of the alternator allowing it to still charge, but also have a direct short.

You probably hit the nail on the head with the motor. When you engage it, go and feel if the base of the wiper is warming up (the center hub, not the tip). If it is, the motor is probably shot. See if you can clean away any debris and check for any loose connections.

sounds like you have a grounding issue possibly a main grounding location. inconsistant grounding of the vehicles control module will cause erratic behaviours. check under the hood for ground locations containing multiple grounds at 1 bolt location.if different "experts" have attempted repair and failed chances are they are all looking in the wrong place.dash{interior of vehicle}..actual cause.{egine compartment or under side of vehicle..ie...ground locations.}good luck and safe motoring:>

Volkswagen/Audi Group VAG has an odd and long standing relationship with a zero maintenance transmission fluid that is based mineral oil. The procedure to check is even stranger, car should be warm and running (for an automatic) on the bottom of the car there will be a combination drain plug with a screw in the middle. Removing that screw should result in about 1 cc fluid loss because here is a small pipe that goes up to the design fill level. To fill there is another plug up higher where you add fluid until it comes out that drain. Not fun.
