This is a very similar problem to the one previously described on this forum. The front AC vents blow slightly cool air (68 F with 81-83 F ambient), while the back blows cold (55-58 F). Blend doors work fine. The front blows cooler when o a long drive (+60 minutes). I only have a cheap gauge sold with a can of R134, butr it shows the low side pressure in the middle of "green" range with only front AC running. It is in the high "red" range (about 1/2 way) when both ACs are running.
