    A/C Blower Issue

    2001 Ram 2500
    A/C blowing cold, but air only blowing out of the defroster and floor vents, doesnt matter what position selection I make.
    Was working fine until it sat for 2 months with tranny problems.
    Any ideas?

    Kind of sounds like the blend doors aren't working correctly. I believe they will throw a code if defective. Have you hooked a scanner to it yet?

    Agree with @walla2k5 on this. Some of the blending doors are broken. Happend on my first truck. The job was a pain in the ***

    Have not hooked up a scanner yet, will do when it cools off, 99 outside right now, no shade available
    I can move the blend door actuator arm in and it blows correctly, but when I let it go, it extends back out again.
    Read a lot about vacuum leaks too...

    Got it!
    Vacuum leak created with install of new transmission.
    Have to verify with trans shop, before I call it complete, but we got her working. 5 hours troubleshooting and it was a 60 cent vacuum cap...sheesh!!

    In case anyone else with 2nd gen has a vacuum leak, I found a great drawing of the 2nd Gen vacuum system.

    Oh man, I misread what year the pickup was, thought it was your 2011. Glad you got it all worked out!
