OK HERE IT GOES. WHAT IS THE FUNCTION OF THE THERMOSTAT CUT OFF SWITCH ON MY 1979 CORVETTE? IT LOOKS PRETTY BAD, PLASTIC BOTTOM FEEL OFF, RE-GLUED IT. I RUN THE SYSTEM; JUST TO KEEP IT WORKING, DO NOT USE IT A LOT.
HOW DO YOU TELL IF IT IS EVEN WORKING? ORIGINAL SYSTEM NEEDS FREON, LOW, COOLS VERY POORLY, ALWAYS DID. LOOKING FOR FREON? COMPRESSOR CUTS OFF AND ON, ALWAYS THOUGH IT WAS DUE TO LOW FREON.
THERE WAS SOME TYPE OF OLD BLACK INSTALLATION TAPE OVER THE COPPER LEAD WHICH IS
IF WORKING, SHOULD I SETUP SOME KIND OF HEAT BARRIER OVER THE COOPER LEAD? LAST NIGHT I PUT SOME PIPE INSTALLATION OVER IT W/ SOME Y TIES, CANNOT STAY THAT WAY, HEATER LINES GET TO HOT. IF THAT SENSOR IS SENSING COLD, I AM GUESSING I NEED A HEAT BARRIER.

Thank you Dave, done, hopefully he will know. Part is for 78 / 79 in Ecklers.
Hey Terry,
Put everything back together. Compressor will not run unless that switch is plugged in. Would be very hard to check the voltage w/ it plugged in. System cycles shortly and after running a while the compressor stays on all the time while running in my garage. Lower line gets very cold and sweats a lot. I will try and fine some R12 and re-service the system one day. Any further advice is welcomed and thanks again for all your help I do appreciate it.

Ken, the switch has to be a temp. sensor, it is clamped to the outside of the low pressure line going into the bottom of the evaporator core box. I may not be understanding correctly what you are trying to tell me. Agree about contamination, it may have some, have never done anything to the system when I restored the car in the early 90's. Had Freon added a couple of times that is all.
Terry, yes, getting cold air in the cab. It stopped short cycling after running it a while. Is that normal or do I have to be driving the car w/ air going across the condenser?
The hotter the abbient temp. the longer the compressor will run witout cycling off. When your moving, increasing the RPM's, and bringing air across your condenser, it will get colder.
No, something different. I don't have what you are describing at all on my 79.
