2G 2g GSX no power to ac dual pressure switch

[RBeha]

No power to ac dual pressure switch. I grounded out the wire that goes to the pressure switch when I was testing it. Now I have no power. I check the wiper fuse and all of the fuses in under the dash and engine compartment fuse box. Need help thanks

Looking at the wiring diagram grounding the wire going to the dual pressure switch might blow the output transistor of the Automatic Compressor ECM.

That looks to be the source of any voltage, and depending on the various switches the voltage goes to the ECU, the A/C clutch relay and the condensor fan relay. In the relay cases the coil provides resistance so you don't draw too much current. Shorting the wire to ground seems like a bad idea.
