When the refrigerant is above 1,470 kPa (15.0 kgf/cm2, 213 psi), the A/C pressure sensor switches the radiator and A/C condenser fans to high speed. BLOWER FAN EVAPORATOR (Absorption of heat) EVAPORATOR TEMPERATURE SENSOR RELIEF VALVE (Relieves pressure at the A/C compressor when the pressure is too high)

What causes an AC compressor to not engage?

If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, or a low pressure lockout. AC compressor clutches receive power in a number of ways. They can activate through a relay that’s energized directly by a proper condition of the low and high pressure switches.
