Q: a/c recharge on 2001 Dodge Stratus

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I went to have my a/c system recharged because the last mechanics discharged the system when they did head gasket work on the car. But when I took the car into another shop, they did an inspection and told me that the a/c control head was broken and needed replacement. But, if the head unit is just the controls for the a/c they were working fine when I got back into the car, but of course, not blowing cold air because they didn't recharge the system. How can I tell if the head control unit is really damaged and needing repairs?

Simply, the system needs to be tested. There is no "easy way" to find out what is wrong; I'm not sure what is meant by the "control head was broken" - broken how? Is it not turning the system on?
They just called me today with a quote on the control head assembly and told me that it wasn't turning the compressor on when the a/c mode was engaged. They didn't tell me that yesterday when they finished checking it or I would have put it down.
It just seems so unusual to me, but I don't consider myself a Dodge specialist. Most times the switches on the vehicle are the least likely culprit. But, if you have a shop willing to stand by their diagnosis, then by all means, go with it.
