I See The Ten Page Honda Bulletin For Failed 02-04 CRV Air Conditioners. That's Lousy.
I see there are 5 versions of what needs to be replaced, depending on the level of contamination residue and VIN. The worst includes compressor, condenser, receiver/dryer, desiccant bag, expansion valve, expansion valve O-rings, evaporator, A/C line, receiver line Areceiver line B, suction hose, and discharge hose. They show almost 6 hours labor, including R&R battery, bumper, radiator, and alternator (and that's under warranty !).
I would sell the car, letting a buyer know the A/C doesn't work, and buy a different vehicle, one with working A/C. I'd be afraid of spending all that money and having unreliable A/C.
