Compressor fan running without engine on

Hello, that box is the relay box for the fans, here's a diagram of that circuit (picture 1). So either that relay is stuck on if you see how it works, the condenser fan has 2 relays it needs to go threw to work. Fan relay #3 first, then grounds threw fan relay #2, the ECM grounds all 3 fan relays. Now I've seen a bad ECM ground cause the fan to stay on all these time too, it's a default strategy so if the ECM fails the car won't overheat. The 2nd pic is the ECM grounds, they're all white/black wires, labeled E01-E05 at the ECM connector. These should be checked.

This is the tie in between the ECM and 3 fan relays, the small green box at the bottom of the picture. The light green/black wire and the red/white wire. The 3rd picture is the ECM grounds, there's 5 all white/black wires. The pressure switch probably shares a reference voltage with other sensors and/or ground wires, that's what that seems to be. It's possible that the box you're unplugging is shorted inside and sending power or giving ground to the relay circuit.
