This stuff can be complex.
And a lot of shops are inept or shysters.
I’ve found this useful
Lockbox, Celerity and Kay Ludlow are spot on. If the compressor seized up and it’s replaced without replacing or flushing the other contaminated components in the ac system, you’re going to get another failure in short order. Are you sure it’s the compressor that failed?
I’ve heard the replacement compressors supplied by Honda are better than the originals, but then again so are the aftermarket Chinese ones.
Any reason to salvage the vehicle, other than it’s annoying to scrap an otherwise working car over a stupid air compressor? It it in really good shape otherwise? Having a shop do the work to properly replace and flush the system along with installing the new compressor is going to be expensive.
Yes, and first suspect is the TXV. might be causing ‘slugging’ liquid refrigerant.
Also if several compressors have been replaced likely too much oil in system.
I had a AC compressor failure on my ‘83 Accord and the oil looked like a burnout, even though it’s belt driven, no motor.
New condenser and add an inline filter on compressor suction connection.
Yes, know about all of that and it has been done. The remanufactured compressors (we went through 4 from O’Reilly’s) are NOT holding up. The compressors are failing. System switched to 134A.
Already replaced the condensor, expansion valve, compressor, drier. Really making an effort NOT to give up.
Yes it was R12 to begin with. Now 134A. I suspect this IS the problem.
Engine is 2.0L fuel injected.
Years ago bought a 90 Mazda that was originally R12 and had been converted to R134 somewhere along the line. The AC was very weak despite having a good charge. I converted it back and it was pretty good.
I really think that is what needs to happen.
R12 is really expensive these days, but perhaps worth it if you really need a good functioning system. Just make sure it’s 100% leak tight before loading in that precious freon.
