Thanks for the reply,
The ERLS has already been tested and is functional, that was done weeks ago;
I believe that the compressor (or at the very least the compressor clutch) will need to be replaced, however both are entirely useless (except to act as a serpentine pulley) unless the system holds pressure; to my knowledge it does not.
To be clear, the compressor does not engage, whether or not it will is another issue entirely. I'll see about testing codes.
What I need at this point is a quality diagram of the system;
I know where the condensor is (obviously), I know where the compressor is,
I know where the receiver/drier/accumulator is. At some point however theres too much junk in the way for me to find the expansion valve and the evaporator.
At this point I think my plan is as follows;
0. Leak and pressure test the system;
1. Remove compressor, accumulator, expansion valve.
2. Flush the system of any contaminants.
3. Replace with new parts; possibly replace or reuse sensors, I'm not decided.
4. Re-charge leak/pressure test
(Can I do step 4 without hooking the system up to a vacuum pump first?
5.Bring system to a mechanic to have it properly charged (if step 4 is successful)
6. (if step 4 fails) Find leak and replace necessary component (hopefully just hose assembly)
7. Re-charge/leak/pressure test.
8. Repeat (5).
Do these steps make sense? Am I missing anything? Am I hopelessly over my head?
