Compressor HVAC: Description and Operation
1994 Acura Integra (GS-R) L4-1797cc 1.8L DOHC (VTEC)SECTION Description and Operation
Battery voltage is supplied through fuse 35 to the A/C compressor clutch relay contacts at all times.
With the ignition switch in ON (II) voltage is applied to the coil of the A/C compressor clutch relay through fuse 13. When you push the A/C switch ON, and the heater fan switch is in position 1, 2, 3, or 4, a ground" input is provided to the Engine Control Module (ECM) through the A/C thermostat and the A/C pressure switch.
The A/C compressor clutch relay is grounded by the engine control module (ECM). When energized, the A/C compressor clutch relay allows battery voltage to turn ON the A/C compressor clutch.
The A/C ON indicator light comes ON when the A/C system is running.
