    Had a quick look at this but not familiar. No AC fitted, seperate temp control for left/right.
    Distribution seems ok, fan works all speeds.
    Valve assembly under bonnet, offside, has what looks like two motorised valves, presume these are left and right. Unlikley that both have failed.
    The rotary controls for fan and distribution have no illumination on one and a steady flash from the other. Guessing at bulb failure for one dial and the other is indicating a fault.
    Question is, common fault or am I wasting my time? Does it need to go to dealer or a couple of pairs of moleys for the hoses
