1983 Blazer 6.2 Turbo diesel A/C System

I fixed my fuel issues thank you everybody for the help thus far. It has been a blessing to have all of your knowledge and support. *Tear...so now I want to get my A/C system up and running. All I know for sure is my compressor is seized and it needs replacing. I bought it this way and the previous owner never tried to get it working. He just removed the belt and left it as is. Where do I go from here? Should I get the system flushed and then replace the compressor? Or just replace the compressor and refill the system? Or start from square one and replace everything/seals/hoses/components?Any advice/help on the issue anyone can offer? Thanks You in advance.

I would assume the compressor is seized, not the condenser. The condenser is in front of your radiator. The compressor is part of the engine acces. I would replace the seized compressor before doing anything to the system, as it would be a waist of money.

Yes I corrected my error. You are right I meant compressor.

First off, to do it right is going to be expensive. With that aside, what pump do you have? A6? Is it black, round, and about 14" or so long, like a hot dog? If it is, those pumps kind of suck if you run R134a freon. They were designed for R12 and the higher pressure R134 generates can be tough on an A6. The best way would be to convert it to a Sanden compressor, which is designed for R134a and long lasting reliable etc. You can use an A6 but don't be surprised if eventually you have a front seal failure, or another seized pump. You need to change the dryer, which is that silver canister coming out of the HVAC box and the orifice tube that is down inside the line coming out of the evaporator. If it's old, clogged up, it may come out in pieces, or not come out at all. You could get stuck buying a new evaporator in that case, whcih is not a bad thing. A good idea would be to change the rubber lines, and the condensor too to a parallel flow R134 condensor.

Old A/C's are expensive to get going, RIGHT. Slapping it together without doing all the steps just leads to a leaky problematic system.
