I just got back in from my garage. I have a 1985 911, and I just finished up on a AC main fan (evaporator) blower upgrade, and a new full adjustable fan blower switch. The factory AC switch has low (is that blowing?) medium (I think I feel something) and full blast. Now I can set it to whatever level I want, and I have a LED light that that tells me if the compressor is running or off.

It is the Griffiths Technology Kuehl Speed controller system along with his aftermarket fan motor has 30% more power blower on max. It is not a simple swap, it has controller boards for the fan switch, and new wiring, and it takes a while to do. I just went for a test drive, and it is only 69 outside so the AC kicked on and it was not long before it started to cycle. Cool, er Kuehl.
