Hello to all out there today, I'm having an AC problem on a 1990 SOHC missing ground signal to compressor and condenser fan. Ac switch on dash will not light up unless you put false ground to system, AC guy looked at it and said most likely the ECM has bad pin what do you think ?

that's pretty likely...these cars are old...do what you need to get that signal, I would recommend relay of some sort to keep from burning out your compressor
