Thanks Skip for getting back to me as this thing is driving me crazy. If I am looking in the correct place between the vent system and the evaporator at the mechanical linkage, there is a white plug with gr/w and blk/yel where the micro switch should be. When completing the circuit on these two wires, AC system cycles correctly.
I got this 86 Brat from the V.I. and it was AC ready. I found the AC componets in a Nevada junk yard. I thought I had all the parts but evidently I was missing the on & off switch. I will try Subaru to get the micro switch kit or do you have any other suggestions on where to find it. I live in SW Florida and there is not much here.
