What happens when the a / C pressure is too high?
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)
Where does the a / C compressor fuse or relay come from?
Walmart is no help and has no clue whats going on. the orange light comes on the dash when you press the button but the compressor never kicks on. There is no fuse or relay for the compressor clutch.

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.

No signal, not compressor running. Get back under the dash and take a look. Sent from my iPhone with Tapatalk. I’m thinking you forgot to reconnect the little sensor right outside the door to the cabin air filter. I believe its a temp sensor to tell the AC to shut down if your evaporator is freezing up. No signal, not compressor running.
