A/C clutch not engaging - 2005 Honda Odyssey
This is a 2005 Honda Odyssey with an A/C system problem. The A/C clutch does not engage, even though the system is full of refrigerant. In this video I will walk you through testing system pressures, and how to test the inputs and outputs of any A/C system.
Engine Performance Diagnostics chapter 3
Symptoms
- A/C clutch does not engage
Tests shown
- how to use system rest pressure to determine state of charge
- how to test the A/C relay
- how to test for an A/C switch or sensor problem by looking at RPM
- how to test the A/C compressor clutch relay for proper control
- how to measure A/C clutch coil current flow
- how to check the A/C clutch for proper power and ground
