So I've read this thread; https://www.r3vlimited.com/board/for...ion-thread-diy and figured this wouldn't be to hard to finally get the AC working (for the first time under my ownership) and have a modern refrigerant.
So I bought everything from the thread and got to work. Well I think my big problem is I have an early car (1986) and I think this write up cover a late model. So the first issue I have is the pressure switches (yes plural) on my drier. What the heck is up with this?
From what I can tell the top one is the standard switch that should turn the fan on low when the compressor pressurizes the lines. That second one on the bottom right seems to be wired to the temp sensors at the top of the radiator housing. So at first I thought maybe the early model pressure switch is a 3 wire, one for low and one for high, but no it is still a 2 wire, just a different connector. I plan on running a cheaper single speed aftermarket fan, so I jsut need to make sure the fan gets single to turn on from the pressure and the temp, not 100% on how to get those 2 feeds from in this scenario.
Second issue. Car had the Denso compressor on it, so I ordered the 4 season Bosch with black pressure switch form rock out, since the stock on had a small black box with a single wire coming from it. However, the new compressor has 3 wires coming off of it? I don't know where they go in either scenario as the compressor wasn't hooked up when I got the car. Can I still use this new compressor or do I need to get a different one?
Any AC guru's got any ideas/tips for me?
TIA
