Re: A/C blowing in defrost mode!

Pretty sure I found the soulution to my problem. I think one of the vaccum lines for one of the actuators was lose. Which caused a slow vaccum leak. I observed the door for recirculation slowly close with the ignition key on in a/c mode. Which it shouldn't do with max a/c on.

So I just pushed all the vaccum lines tight on the actuators and I haven't had a problem since. I guess the system went haywire when the vaccum was lost. Doesn't make since to me as to why the climate control would display eratically though. I also made sure the hvac control box connection was secure. Save myself a lot of headache. So im happy
