Problem #1 I need help I bought a 1997 740il at auction. At first the wipers were stuck in the middle of the windshield? Didn't go down. After letting car runs for 30 minutes hit the switch and they went down only worked for a few seconds on High and then stopped all together again? Haven't worked since. Any suggestions as to what could cause this? I have tried replacing the handle switch on the steering column with no success. All fuses seem to be fine. The only thing I don't know about is if there is a relay to check? Any help would be great.

Problem #2 same car as above bought the car and the radio was not working. After letting the car run for awhile the radio started to work then I turned the car off and the radio no longer works. Any ideas?
