Spn-876 compressor clutch circuit.

The purpose of the A/C clutch relay control circuit is to control the operation of the air conditioning. This is accomplished by providing power to the A/C clutch to engage the A/C compressor. Based on the specific vehicle, this circuit can be very complex and include several control modules. Code P0646 is set by the PCM when it detects a low ...2. Check which type of compressor magnetic clutch relay is fitted to the fuse box. Note: The relay manufactures name is marked on the top of the relay. If the relay is manufactured by Omron, replace the relay and any other components damaged as a result of the relay failure.Compressor clutch circuit number 876 dated valid but below compressor clutch circuit number 876 dated valid but below normal operation range replace the compressor expansion valve and dryer charged it still has code there's another code in it to HVAC temperat …A damaged or seized A/C compressor can prevent the clutch from engaging. If the compressor is not spinning freely, it will be unable to engage the clutch. 6. Broken Drive Belt. The drive belt connects the A/C compressor pulley to the engine. If it breaks or becomes loose, the compressor won't turn, and the clutch won't engage.

Insert both ends of a wire into that plug. Turn on the engine and the AC. If it works then the switch is preventing the AC from operating, either due to pressure being out of bounds or the switch is faulty. If it doesn't then the clutch has an issue ranging from a broken wire to a failed clutch.When resolving the P0645 fault code, start by checking for damaged components and connector pins. Visually inspect the wiring harness and connectors for any signs of damage. Look for broken, bent, pushed out, or corroded pins in the connectors.

Thanks for the update. That fall code is directly related to your AC compressor clutch problem. The ground comes from and through the ECM and controllers. The controllers will connect ground through its inputs and outputs even for fan functions as well taking the place of a relay in the circuit in a lot of cases.

Relieve the tension on the serpentine belt tensioner and take the belt off. Remove any components that are in the way of the AC compressor. Most parts can be removed with a socket set. Disconnect the lines from the compressor. Jam a piece of cloth into the lines to keep them sealed and protected.

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. Insert both ends of a wire into that plug. Turn on the engine and the AC. If it works then the switch is preventing the AC from operating, either due to pressure being out of bounds or the switch is faulty. If it doesn't then the clutch has an issue ranging from a broken wire to a failed clutch.Instagram:https://instagram. hobby lobby haywardmurphy's law bar rescue still openlindy's auto upholsterymugshots arizona pima county My Freightliner is making a loud high pitch whining noise.
