Fan not blowing!

[mspillberg2000]

My engine was washed this morning, and Now my ac fan is not blowing at all. Before wash everything was fine. I have the manual Ac controls and when I turn it on, nothing blows. No Ac nor fan in front or back vents. Its like these is no power going to it.
I think its an electrical issue!? But don't know where to check!
Can someone tell me if it could be the fuse or a sensor? I checked one of the blow fuses and it was fine, I haven't checked the larger blow fuse. I check the aux/pusher fan, and it works fine. AC compressor works fine. I just don't get any air blowing out of vents!
BMW service can't look at it until next week.
So much for cleanning under my hood!
Thanks,
