    There are many things that can cause the a/c to fail or not blow sufficient cold air. There are no Service Bulletins regarding any "common failures" and I have not seen any on the Matrix.
    The system will protet itself if there is a loss of refrigerant so as not to damage the compressor.
    You need a wiring diagram and pressure gauges to properly diagnose the system.
    The pressures should be Low side 1.5 to 2.5 kgf/sq cm , High side 14 to 16 kgf/sq cm.

    I have a 2003 XR, one of the major problems when the a/c doesn't kick in could be the wiring cluster that goes to the dash panel. If your dash lights r NOT working u have to doublecheck to make your compressor is receiving current. If it does not receive current the likely electrical problem is the cluster. Average cost for a cluster between $250 & $400..I just had to replace mine.....
