Title pretty much says it all... yesterday, I noticed my AC wasn't working in the afternoon, but it had been working in the morning. Did a quick visual check of the system, fuses, lines, etc... and noticed about a dime sized rock (or something) had impacted the condenser, right where the vents in the front bumper cover are straight through to the condenser. The vanes where the refrigerant passes (not just the fine heat sink vanes) are displaced and damaged... without doing a thorough diagnostic yet, I'm operating on the assumption that the condenser is cracked. Assuming it is cracked condenser, what else should I replace? Most places online are suggesting the orifice tube and accumulator, but are there any other parts of the AC system that should be replaced while we are breaking it open? Compressor seemed to be running strong, but we just rolled 150K on the truck, so should I do that just on general principles?
