    I have a 92 Grand Caravan and when I step on the gas the air
    conditioning/movement system switches to just blowing in the defroster mode.
    I heard there was a new check valve to correct this problem but cab't find
    the original source of that information. Also where is this check valve
    located?
    Much thanks to all who respond

    Leaks in the vacuum system can also cause this problem. At the age of
    the van, I wouldn't be suprised if your vacuum lines aren't hardened and
    cracks. Less than $15 investment in tubing and a couple hours under the
    hood may fix the problem.
