88 Century a/c question?

Hello everyone, I have an 88 Century, 2.8 L. I converted it to R-134, It is blowing cold air, but the comp. isn't cycling. I figured out I need to change the cycling switch because the pressures are different, but I can't find the switch on the car. Does anyone know where it is located? Thanks jag

By cycling do you mean the compressor runs all the time? When the lever is on Max then it will not cycle on and off. When it is on normal or defrost it will.
