I have a 89 535i manuel. There is smoldering smell coming from inside the car..really strong. I noticed the wipers have been all of a sudden running really slow. My girlfriend noticed the smell about a week ago..its now worse. I think it may have to do with the fact that she accidently turned the fan speed control all the way around in a full circle when drunk. Since then the fan speed has not worked correctly or the heat control. Heat only works when the car is moving...sometimes we can't turn the heat off at all or the fan. Any insights.....

Your light headed buzzin friend
