I just charged my AC with R-134a it is the first time that i have AC in this car when i bought it every thing was disconnected and in boxes inside the car. Any how the high pressure switch on the back of the compressor does not work. If it is possible can i remove the switch with out discharging the system? and if i can't then can i just skip the switch and have the compressor come on as long as there is pressure in the system??? Thanks ahead of time
