Manually turning off the CCU and restarting the car has not yet been successful. My commutes are mercifully short given the heat today (about 96 degrees out), so I'm not in the car for more than 10-15 minutes at a time, but there's not even a hint of air coming from the fan.

I found a multimeter and am about to go dig into the car a bit and see if I can figure out what to measure.

Otherwise, what's the consensus on whether this is just the regulator or the whole unit? I'd like not to spend any more money than necessary, and I feel like I'm getting both answers. Maybe voltage readings will help -- I'll post back if I get something this afternoon/evening.

Thanks -- yet again.

Cheers, John
