A/C issues

[Big T]

I have a 2001 EB 4x4 that I purchased a couple months ago. I have been reading the forum and it is a great help.
I am having issues with the a/c. It will work fine on either max AC or set to automatic, then suddenly it will stop blowing and all air goes to the defroster vents for a bit. After that it will go back to the front vents. This cycle continues at random.
It is not a big issue but I would like to fix it when I get a chance.
Anyone else had this problem? I did not find it when I did a search for it.

do you have climate control? If so it sounds like it may be faulty- I have no experience with this but just an idea

I do have the automatic climate control. It does the same if I set it on automatic as it does if it is set to max a/c. There seems to be no difference.

Big T send me a pm with your email address. You need to run the diagnostics on the EATC, if no codes then check the vacuum lines.
