AC\Heat not blowing

Hi,

This has happened 3 times in the past couple months. I start my car up and turn the AC on and I can hear the AC compressor come on but no air comes out of the vents. I mess with all the settings and turn it off and on, no heat comes out when i switch it to heat and no air comes out when i switch the AC off. Sometimes I think I feel a little air (about 2 seconds worth) when I switch the AC off but leave the fan setting on full. The first time this happened I turned the car off and started it again and it worked fine. The last couple times I had to restart the car 5 or 6 times. Usually the AC work fine, but this happens every now and then and Ide like to get it figured out. Once again, the AC compressor definitely is comming on cause I can hear it and feel it in the idol, but no air comes out of the vents at all. Has anyone seen this before?

Thanks a lot

- Justin -

That seems like a loose connection as a first guess.

Do you mean in the wiring? Where is the best place to start looking for that?

Thanks

I think I'd start at the fan switch.

Actually, this sounds like the blower motor resistor needs replacement. I know it's behind the center console, maybe the e36 guys can help further.
