'84 has a fan switch which is compressor mounted. The switch that's connected to the compressor manifold is a pressure cycling switch. The cycling switch is a GM# 10007057 and the fan switch which is retained by a snap-ring is a GM# 2724279. Those numbers are OE/GM original and the 10007057 is a difficult find.
