    What's up everyone, got a bit of a question here.

    I began working on the A/C in the 5th again today, and when I turned on the air, I only got airflow from the defrost, not the vents on the dash. I couldn't redirect the airflow to save my life.

    So I took out the panel under the driver side of the dash, and little green chunks of what used to be rubber fell out, and I noticed that the color-coded vacuum lines were all hanging, disconnected. I'll attach 2 pictures for a reference.

    I know that finding another green connector will be near impossible, and I'm pretty sure that I can simply re-attach the colored vacuum lines to their corresponding black line using some small pieces of rubber vacuum line, I just don't know what the order of the colored lines is in order to reconnect them properly. Does somebody have a picture of this assembly that is still in tact so I can reference that? Any other tips? Thanks.

    BTW, I did cap off the pink line, since I determined that was the vacuum signal, and I didn't want a vacuum leak.

    Another board


    I use vac tubing to bypass the rotted connector.
    as long as the colors go to the right ports it will work.
    The one with the x has nothing going to it.
    and a red one is on the other side of the connection going to the empty spot.

    Dark Green, Red, Purple, empty


    I pulled a perfect, non rotted complete vac system,
    from my 81 Lebaron parts car.
    I use it as a reference for the other Ms.
    I followed this for my 88 Diplomat AHB and everything works as it should.
