I have a 98' Wrangler Sahara 4.0 6cyl. For quite a while now my ac has been having problems with what i assume is the vacuum. It works, its cold, but anytime i accelerate for a moderate period of time or go up hills (at higher RPMs) the air slowly dies out and i can hear the vacuum building up with air, but as soon as i decelerate the vacuum releases and the air works great. it never fails to happen everywhere i go.
help would be awesome
