    I have just replaced all of my ac components. Ac runs great and is cool, until I accelerate or go up a incline then heat poors through the vents. This is not a blast of air, it is like the heater is on. Is this the compressor, the valve that goes into the cab or slippage. After I level off the cool air comes back. Any suggestion

    If it only happens when you accelerate, it's probably a vacuum leak somewhere. Take a good look at all the hoses under the hood and pay close attention to the vacuum reservoir and the check valve in that line. Easy fix.
    Good Luck and God Bless

    I have replaced the fan, the ac heater valve.
