Working on a 92 Honda Accord 2.2 liter . a/c compressor not coming on . you can ground the pressure switch and the unit will run and cools good . the relay has already been replaced and fuse checked good. starting to think that the pressure switch is the problem but when I ground it and the compressor works shoudnt it turn off when I turn off the switch inside the vehicle? if anyone has the wiring schematic or any information on this it would be greatly appreciated.

 

welcome to the forum. check the amount of the pressure in the system. the pressure switch can go bad and either low pressure of bad switch will cause the compressor to not get pwr to come on.
