The shaking and shuddering is especially terrible below 20 MPH.“ Solution “The 2004 Honda Civic Hybrid shudders when braking or accelerating at any speed. “I have 147k on the original CVT and for the past 6 months or so, the transmission will literally slam into gear when starting out and makes a loud ‘thump’ when I let off the gas.” Later that CVT developed increasing problems with judder.”

If that works, the problem was a bad relay. If both are good, swap the AC compressor clutch relay. If you don’t see battery voltage, check fuses 22 and 25 in the underhood fuse box. Remember: The blower motor must be running for this to happen.Ĭheck for power to the AC compressor clutchĭisconnect the connector at the AC compressor and test for battery voltage with the engine running, AC ON and blower ON. If the HVAC head sees a return voltage, it sends a digital signal to the PCM to provide power to the AC compressor clutch relay. If you don’t see that, check for an open between the HVAC control head and the thermal protector connector.

The HVAC head provides a 12volt reference on the blue/white wire and looks for a return on the red/white wire. If the thermal protector shows continuity, check for power and ground to the thermal protector connector.

To test, disconnect the connector and test the thermal protector using a continuity feature on your meter. When the compressor overheats the thermal protector opens, preventing power from reaching the clutch. The AC thermal protector is located on the compressor. MOST COMMON CAUSES OF HONDA AC CLUTCH DOESNT ENGAGEįaulty thermal protector Faulty AC compressor clutch relay Incorrect air gap on the clutch (assuming it has power) The Honda AC thermal protector must show continuity for the AC clutch to engage If the clutch doesn’t engage, perform these tests. If so, check for Honda AC compressor clutch engagement. To start, check high and low system pressures to make sure you’re above the high and low-psi cutoff limits.

When you encounter a Honda AC clutch doesn’t engage condition, the problem could be: low refrigerant charge, failed AC compressor thermal protector, or faulty AC clutch relay.
