Vacuum leak.
You sure the AC actually goes off or just changes from vent to defrost.

I would think that it is a vacumn issue.

Thats what Jesilvas said. Can you post your reason you think that so everyone isnt posting i think its a vacume leak.

The hubs are vacuum operated, it's common for the vacuum operated hub seals to fail. Since the OP posted that it only has a A/C issue when in 4wd, that is a good inducation of the hub seals are bad.

I engaged 4x4 earlier. The front hubs don't engage unless done manually by turning to manual. Sounds like a vacuum problem.just need to see if fix/repair is cost effective!!

Sorry did not see what jesilvis said. Lilpooh thoughts were what I was thinking with so little info from the OP.

Mine auto hubs haven't worked in 2 years, I'm waiting to fix them when/if I need to replace the ball joints or hub assembly.
