I'll get back to you on this tonight, for reasons I'd like to keep under wraps.

I have that same AC/Heater unit on my 78 KW. Any tips on troubleshooting, and getting it to work would be appreciated. I made the AC compressor turn on locally the last time I was messing around, but that was as far as I got. When manipulating the controls on the box, all I get is an air hissing sound, and that's it.

My guess says it goes to the fresh air/recirculate door. Max a/c is achieved by closing off the outside air and recirculating the cab air.
