Recently I have had a problem with my 98 523. This happened up in sunny Queensland first. When I parked the car in the sun and come back to drive off after about 5 minutes the blinkers would not work on the dash but would still be working outside then the CD/radio would go out and stop working(or no sound anyway). This seems to happen only when the car warms up and if I put the air conditioner on it takes longer for it to happen. Obviously it is a heat problem, but has any one else had this problem or knows the fix. Thanks
