A/C dripping from condensation?

[FlameBroiled]

I just took my first real test drive in my customers 67 LS7 with VA, 45 min with the AC on low but maxed on the temp setting. And the same thing happened to its box, sweating like a fat guy standing still.....

So far I have had nothing but problems with the VA and this will be the last one I plan to install. Anyone else have problems with the fan speed switch going to high speed when turning it off?? I have VA on speed dial and have replaced most of the components. I am getting tired of tearing out the interior just to try the next suggested fix..... fan switch, Ecu, and heater valve... whats next?
