Spn-876 compressor clutch circuit.

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. If your Air Conditioning compressor isn't working (the clutch won't engage) then watch this video. The A/C switch on the dash switches the compressor on, wit...What I have found is that the clutch and compressor are good. I see the request for AC to the body control module.
