Sounds like it's low on freon. Must have an A/C leak somewhere. Check for oil escaping from a connection en-route in the A/C system. Or a bad component! Good place to start!

Where is the low pressure switch for my Honda Odyssey 2003 AC ?


The A/C pressure switch is located in the high pressure line (the skinny one) on the passenger side of the engine compartment just under the fuse/relay box. The switch has three functions: <28 psi, the switch opens to protect the compressor from lack of lubrication. >220 psi, the switch shifts the radiator and compressor fan to high speed. >455 psi, the switch opens to protect the compressor seals. Check to see if you have any powertrain DTC's first. A faulty engine coolant temp sensor can cause problems with the compressor clutch relay. If the radiator and compressor fan come on with the A/C on but the compressor clutch does not operate, check the compressor clutch relay. You can also obtain Heater control panel diagnostic trouble codes (DTC's) by turning the ignition switch on. Then turn fan switch off. Press recirc button to select recirc air. Press and hold recirc to turn off recirc air but this time continue to hold the button down until recirc light comes on for two seconds and then goes off. If there is any trouble, the recirc light will then blink a code (if no trouble, the light will remain off) 1 blink = problem in air mix control motor circuit. 2 blinks = a problem in mode control motor circuit. 3 blinks = a problem in evaporator temperature sensor circuit. (this one could be a factor in your case) Turn the ignition switch off to end the test.

I agree with Emissionwiz, this is a unique problem that I have not encountered. This situation is def one that merits "hands on" diagnosis;

BUT,

If you want an educated "guess", (and this is ONLY a GUESS),
I would suggest replacement of the RPM sensor on the A/C compressor....HOWEVER, I would NOT guarantee that will cure your problem.

AC dask board signal


Replace the A/C compressor revolution sensor, bolted to the side of the compressor, unless the connector was inadvertantly left unconnected. This is the only reason the AC light will blink.
