94 Eagle Vision - A/C problem - Code 33

I have my check engine light coming on and I get a code 33 (clutch cutout relay). A/C doesn't throw cold air. Someone told me to charge the system. I took it to my buddy to charge. No luck. He put gauges on the high and low pressure sides. The high side is reading only about 110 psi while the low side is about 110 to 140 psi. Does anyone know what could be causing this? Restricted orifice tube or bad expansion valve or something else? Any info would be greatly appreciated. Thanks!
