I have a 84 ElCamino. I am looking to get the AC working again. I opened up the heater core and accumulator box to replace both but found no temp switch to the relay for the compressor clutch. Just found a crimped wire from the relay into another smaller gauge wire. Was this a bypass? Did they stop making this temp switch? I can't find it anywhere. It's supposed to mount with a simple hose clamp to the liquid side input(lower tube).
