Ok, so I unhook my lines from my compressor today. I believe I have a blockage somewhere. I start back flushing my the proper sovent thru low pressure side by the compressor and I had the line off the drier. Well I think I found the blockage, a whole bunch of ceramic beads came out. I guess they came out of the drier. My question is, do I need to pull the evaporator and expansion valve? Or ? Thanks for any advice.

 

The Receiver/Dryer cannot be cleaned and therefore must be replaced when doing this kind of work on the AC system

I always recommend replacing the Orifice tube/Expansion Valve when flashgun the AC as well

You don't need to pull the condenser or the evaporator, just clean them out well

Ensure you add the proper amount of oil and R134-a by weight back to the system when you are done and after you have faced the system down
