    Default help air con not engaging.

    was wondering if anyone had any ideas why the a/c pump on my VX II v6 wont activate, when i push the button the light comes on and the thermo fans kick in, but the pump doesnt activate. It started 6 months ago as an intermittent problem, just wouldnt kick in every now and again so i got the system regassed and new filters put in, and it worked fine for about 4 weeks and then went intermittent again and till the point where it wont activate at all.
    Would this be a dead ac pump, or could it be something small that can be easily repaired??
    any help will be great thanks.

    do a search
    could be a number of things ,did the ac place that re gassed your system put a dye in it ? if so go buy a cheap ultra violet light and check for flouro dye spray in your engine bay

    could be a number of things
    compressor
    tx valve
    condensor
    leaky hose
    leaky "O" rings
    evap unit

    The compressor clutch in mine died, maybe the same for you?
