Spn-876 compressor clutch circuit

A hot clutch is a sign of a slipping clutch. If the compressor clutch is not engaged, the clutch may be bad, there could be an electrical problem in the circuit, or the system could have developed unusually low pressure, potentially because of a leak. Your repair manual can tell you how to check for power or voltage to the clutch.

Jun 13, 2011 · Your code you are listing is for an open in the a/c compressor clutch circuit. You can start by checking your clutch itself to see if its open before opening up your harness. If you could check the ohms of the clutch should be anywhere in the range of 1.0 to 15 ohms. If you are reading OFL the clutch is bad. The compressor clutch should ahve a good ground through the mounting bolts. The single lead going into the clutch electrical plug receives power from the compressor clutch relay. The relay should ahve power coming into it on 2 teerminals; one should be hot at all times, and one should have power only with the key in the run position.1. The AC Compressor Clutch System Has An Open Circuit. The AC compressor clutch system is regulated by an electrical circuit, as previously stated. In a closed circuit, it should work. The AC compressor clutch will not engage if the AC system wiring circuit has an open circuit.
