BMW/Heater Fan

Question
Hi Josh! The fan switch on my 91 BMW 525i only works in the '4' position. It doesn't blow in any other setting. All the fuses seem to be intact. Any suggestions?
Andrew,
I'm no expert with the 5-series, but I have heard of this problem. There is a circuit board that the fan connects to, and it's called the "fan sword", because of it's shape.
Replace this and it should fix all your problems.
Good luck,
Josh

Expertise
I can answer questions related to the BMW e30. These are the cars produced from 1984-1991 (1992 for convertable) in the United states. I am more fluent with the six cylinder models, although few things changed for the 4 cylinder cars. I know most of the problematic areas of these cars, and have found ways to fix them.
Experience
I have owned six different E30's over the last 10 years. I do all my own work, and know about ever nut and bolt on these cars.
