My clutch failed on my a/c compressor. No leaks or pressure loss until I disassembled the condenser. I bought a new compressor, condenser, drier and expansion valve. Set to task putting in the new condenser today… Buick put latch assembly brackets around it so I had to take off the whole bumper/grill, headlights, under panel, etc. What a pain!! So, I get the compressor in and condenser, Started to look for the expansion valve and guess what??? it is behind the firewall. You have to take the frigin dash off in order to replace it!!!
So, since it appears that there is nothing internally wrong with the a/c, do I really need to replace the expansion valve?
