1993 civic ex 2 door a/c wire question

[itsmeek]

hi everyone,

the wire that controls the a/c and heater blower, where does it plug into? when i hook a tester up to the end of the wire that is underneath the dash and i mess w/the blower control on the instrument panel, it gives me power so i know this is the wire that controls the fan, however i can't figure out where it plugs into on the other end so i currently have no a/c and it's really hot outside. any help would be appreciated. thank you.

if its the blue with red wire you are talking about it goes to the pressure switch. Basically you push in the button the blue/red wire sends power out to the a/c pressure switch. If the pressure is right that switch send power to the a/c compressor and energizes the coil and engages the clutch.
