hi everyone, new member but long time reader of all your great info. this is my first post so be gentle. I have a 1984 chevy c10 305 vin code h. bought new when I was discharged with money I had saved up. has not been my daily for years but still a great truck.
I have been trying to get it to be able to use on a regular basis. I'm down to the air conditioning system. It has not been used in about 10 years, so its kind of a 3 season truck. I figure if the evaporator is still good the rest of the system wont be too bad to work on. any ideas on how to start this project would be much appreciated.

Not enough info. Is the system intact and just not blowing cold?
-
everything looks intact. it does circulate air when turned on, nothing cold. spent a couple years sitting idle when I was in bagram. has not blown cold since.
-
Probably just low on refrigerant, or a dead clutch cycling switch if pressures are still good. I would change the accumulator regardless, since you'll need to convert to r134a unless you have a r12 source.
-
So unless you have the tools, which it sounds like you don't, it'd probably be best to have a shop do a performance test and either top off the system or retrofit it for you.

Agreed with VZ, a shop can tell you if you are low or empty, and do the work.
I had it done to my '78, it still had some pressure so the accumulator had not been exposed to open air/water, and I did not change it out.
You can buy the valve converters for under 10.00.
Costs about 150.00, they did the evacuation, then recharged and added oil.
