basically what happened is my a.c. compressor does not want to turn on unless I rig it up directly to the battery I checked the fuze box under the hood and did not see where the a.c compressor relay would go since it doesn't show on fuze box cap I did see a fuze on the inside and that fuze is corrently getting power but still not power to compressor any help would be appreciated thanks in advance

What is the history on the A/C unit? Where are you located (temperature wise)? Does the condenser fan run? Do you get cold air when jumped?

These systems have several things that may stop the unit from working.

If the compressor only works when jumped (and provides cold air), you may have an issue with something controlling it or signaling it. We need to know the year and model of Civic you have to best assist. It can be an issue anywhere with the blower switch, A/C button, ECU, relays, condenser fan, charge level, outside temperature, or wiring in between.

first check and see if there is continuity at the pressure switch, if not then there is a leak
