Spn-876 compressor clutch circuit.
The compressor magnetic coil wiring can be defective. You can check it by testing continuity between the two ends of the coil. If the circuit is open, then the coil wiring is cut somewhere. You will need to get the magnetic coil replaced, which in most cases would be cheaper than having it repaired. The compressor clutch could be slipping.
HVAC Compressor Clutch Circuit How to test and diagnose the A/C compressor clutch circuit. Explains the HVAC electro-magnetic clutch circuitry, how it is connected to the ECM, what controls it and ... That fault SA 25 spn 876 is for your compressor clutch. The clutch on your AC compressor has a return voltage too low. I recommend either replacing the clutch or the whole AC compressor. Sometimes the wire harness will cause the low voltage, but it is more common to have the clutch burn out behind the locking plate on those Cascadia trucks.

Alternator was charging only 11.8 .Resistance Test: Perform an A/C clutch coil resistance test with an Ohmmeter. Typically, a clutch coil should be between 2 and 5 Ohms, and any reading below 2 Ohms or over 5 Ohms indicates a bad coil. A reading of 0.00 indicates that there is a shortage in the windings. A reading of O.L. or infinity indicates an opening in the windings.A/C Clutch Relay. The air conditioning electronic control module can control a high-current component like the compressor clutch by applying a low current to the circuit's relay. Electromechanical relays use a coil that controls contacts or an arm that swings between two contacts. When the relay is open, the compressor's clutch is disengaged ...
This can include a blown fuse, a tripped circuit breaker, or a faulty capacitor. These issues can prevent the compressor from receiving the power it needs to function correctly. Mechanical Problems: Another cause of a non-spinning compressor can be mechanical problems. This can include a broken belt, a seized compressor, or a faulty motor.
The most common reason why your AC clutch is not engaging is that the AC refrigerant level is too low or too high. It can also be caused by a faulty high or low AC pressure switch, a blown fuse, a bad AC clutch or a bad electrical connection. Here is a more detailed list of the most common reasons why your AC clutch is not engaging: 1.
You will need a few tools and about 30 minutes to remove an AC compressor clutch. First, disconnect the negative battery terminal to prevent any electrical shorts. Next, use an AC clutch pulley remover tool to remove the center bolt holding the clutch in place.
