My Golf has some spooky electrical habits -
1. While parked, one night, the radio came on, LOUD. No one had been anywhere near the car fro several hours.
2. On several occasions I noticed in the morning that the windscreen wipers were stopped halfway over the front windscreen - yet there was no rain and the wipers had not been needed when I had driven the car the day before. They had started, and stopped, of their own accord.
3. I often found my car with the windows half-open - yet they were definitely fully closed when I had parked and left the car.
Please advise what is happening here!
