Check to make sure your evap drains are clear, and try blending the air a little. Put the temp on say 65-68, or 18-20 rather than low. It isn't uncommon in the high humididty to freeze over the evap. The 129/140 hold enough zone to cool two cars. Beautiful car by the way, Those 140 chasiss are my choice of car, 30+ MPG and all the power in the 320. Just remember, DONT SLAM THE DOORS. I hate adjusting the micro switches.
