I have another electrical problem with the same car I posted with the problem charging the A/C and the problem with the hot terminal on the heater switch. This is a 1972 project car I bought a while ago and now I'm trying to sort out a number of problems left by the PO. The charging system...

What's the best tool to crimp the new connector on, and what's the best tool to get the connectors out of the holder?

Will do. Thx!

Thanks Bill!

Thanks Chris! I bought this one. No problem if I have to return it. What do you think? https://www.amazon.com/gp/product/B0CR7GKSLC/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I wasn't able to find the Craftsman but the one the guy in the video is using one that costs $300+...

Great info Ray. I would have known if you had said you switched to a Sanden compressor. I didn't know 508 was the particular one. And those are some really good advantages you mentioned for the Envirosafe. Thanks!

"When you said that the switch works on all settings I'm assuming the blower functions at different speeds. If so, I doubt if you have a shorted wire, if you did all of the current would be going to ground (easiest path) and the resistor is also okay. The rivet that connects the terminal to the...

I've never used one but I'm willing to learn. When I Googled them about a million pop up. Can you recommend a good one for our purposes? I looked up this video: . The problem here is that I don't want to rip the dash apart and it is EXTREMELY difficult to localize these wires. They are all...

So I cleaned the male and female terminals with a wire brush, I cut the bad female terminal off and replaced it with a new one, and that terminal still gets really hot with the fan on from the key and the engine off. Any other ideas? Does anyone have a wiring diagram to tell me where this wire...

I wish I could say. On my end I flushed the evaporator, replaced the expansion valve AGAIN, took the quick disconnect valve apart, cleaned it, and put new o-rings in it. I also got the service valves in the right position for him to charge it. On his end, I just don't know. Unfortunately the...

My fan blower motor switch was going out and only working intermittently, so I decided to replace it today with what I believe to be a good used switch. When I removed the plug from the bad switch, I noticed that one of the terminals had gotten super hot and melted the black holder it was...

So I shared information from the forum with the mechanic and something must have registered because he was able to get the A/C charged and now I have cold air. Many thanks for everyone's input!

So I can tell you hate R134a. In what ways id Envirosafe better?

Thanks!

Sounds good. Thanks!

Good info, Raydav. At the end you say, "Replace the propane, or not." Are you saying it's okay to keep using the propane as refrigerant? What about the flammability? Then I saw this when I looked up Envirosafe...

Thanks Steve!

Awesome.Thanks! That's very helpful info. "Make sure the compressor shaft keyway is facing towards the compressor head." Is the compressor head the top of the compressor, meaning the keyway would be at the 12:00 position? Kevin.

Thanks. Yes. I saw the compressor running as he was trying to charge it. On the oil, that is a guess. I installed the compressor. Strangely, the instructions said to drain all the oil out of it before installation, which I did. I think he said he installed about 6 oz of PAG oil. When I got the...
