The air conditioning had not worked in several years. Around 2011, I replaced all the hoses and had the system charged with R12 which worked well for several years. Over the past few years, it would work intermittently for awhile, then failed altogether. I had tried troubleshooting it, and thought the refrigerant was leaking and possibly low. I borrowed AC gauges and checked pressures. Tracing the circuit lead me to the low pressure switch. When I shorted it, the compressor would start. The switch looked like it needed to be replaced. I purchased a new switch:
After some more troubleshooting, and some help from Delorean Midwest, the replacement switch worked!
