Sorry, I haven't got back on this. That day after work I went out and the clutch engaged when I flipped my switch. It stayed on all the way home (45 miles) and seems to be working ever since. However if I turn the switch off while it is running, it doesn't seem to engage when I turn the switch on again unless the car has sat for quite a while. It sure is nice to have it work! I'll send a pm to MBDOC.

I'm not too worried about creating ice on the evap coil because the air here is very hot and dry.

Thanks for the input!
