Fan switch normal or not?

[Ivan C]

When I turned the Fan Switch to position 1 with air-conditioning ON, no air blow-out (no different from position 0). In position 2, strong air blow-out.
What's wrong? Please help.

I think each position of the fan switch goes through a different resistor (at least it does on some other German cars I have). I have to wonder about your switch. Position 0 and 1 are clicked on and off the most because you have to go past 1 to get to others. Mine blows a small amount of air at position 0.

In addition to my message, when the car still, no air come from the air-vent when the Fan Switch in poisition 0 and 1. Could I replace the switch if it really out of order?
Please help.

before you mess with trying to replace the switch, spray some TV tuner cleaner in it and work it back and forth vigorously several times. My switch did the same thing 5 years ago. This is how I fixed it and it's worked perfectly ever since.

Lawrence,
Mine also blows a small amount of air at position 0. Do you know what the bad part is? it's such a small amount of air, i just assumed it was supposed to do that. I thought it might have been designed to spin all the time to keep the bearings from sezing up. I know that's a stupid reason, but i couldn't come up with any better reason why the fan ran all the time.

I used to have a 924S does the same thing. The fan would on as soon as I turned key. Very slow spin on position 0. I didn't bother trying to fix.
