i have a 02 nissan sentra my air isnt working from the control switch, so i bypass it with a on/off switch that i ran two wires one from the battery an the other one from the a/c clutch fuse box
no good , get another control switch if that's where the problem is although doubt it,is by doing that your bypassing the line pressure switch and feeding current to the pcm if it commands it on temporally . jump the line pressure switch and see if it kicks in if so then you need more Freon
