Default AC blower fan quit working

Of course on a really hot day the blower fan on the AC stopped working. Everything appeared to be in order with the AC itself: the compressor kicks in, the fans start up, but nothing to push air out the vents. No OBDII codes for HVAC.

Anyone have this happen? Where is the blower motor, anyway? I assume this is going to be a PITA to fix.

2000 C5 convertible.

The procedure in the manual talks about checking the resistors, and the thread you mention also talks about the resistors. I'll check out the module on my car.

Thanks everyone for all the help. The WSM does have troubleshooting steps, but my DVM just died. Since it seemed to be the controller, I took the replace-parts-til-its-fixed route.

I got a blower motor control from PepBoys. Yes, you need to be a contortionist to get at it - it's up under the back right under the glove box. Well, that fixed the problem.
