Hi all.
I could really use some advise as to why my A/C won't engage. It's been retrofitted with 134a.
-The a/c is charged to the correct Max pressure, 45psi, according to my gauges.
-My 2 A/C fuses,(engine compartment fuse box), a 10a and a 20a are good.
-The 4 A/C relays in the engine fuse box are present, yet none click when the a/c button is pressed, (which lights up).
-Maybe it's the pressure switch, but I have no idea of the correct inputs/outputs of the 4 wires, or how to jump it/bypass. (Site glass is clear/no bubbles).
-Juiced up the compressor directly w/ 12v and get icy cold air!
So, any ideas on proper troubleshooting procedures would be Awesome!!!
Mucho appreciated
