Alright. I connected the A/C clutch control to +12 and it seems to have engaged the compressor. The compressor seemed to kick on, and the pressure on the low pressure side of the system went down, although it still stayed pretty damn high. It went from about 110 psi to 80 psi, which is still in the red area of the gauge I have. (Which I admit is not the best piece of equipment, it came with a recharge kit)
Also, I feel no cold air coming out of the vents.
So now I am starting to think maybe there is a blockage? Unless there is a valve or something that is not opening.
Is it possible that the reason the compressor will not engage is that the pressure sensor is sensing that something is blocked or something and that is not allowing it to come on?
Someone told me I should try letting most the refrigerant out of the system and then re-charging it. That does not really seem like such a great idea, but I am not sure. Anyway, it is not the ozone depleting type, so I guess I do not have to feel bad about that if I do.
