As I said, I believe you are short on refrig and the fans are running off that wire they have tapped into going to radiator. When I asked that you put the wires back on the sw, I also mean for you to disconnect any wires that have been added ..You want stock wiring for me to diagnose .
What I now want you to do now is unplug the high side pressure sw and do a continuity test across it's terminals while the a/c is running at 2k..that will tell you if the pressure is reaching cut-in spec at the switch.
You can do this simple test w/ohm meter
