So the engine got replaced in January due to seizing and until now, I never needed to use the A/C. Looks like it's blowing warm/lukewarm air on LO. I'm assuming that something happened during that major surgery and it is now low on freon(or empty). Any decent a/c shop should be able to test for leaks and refill, I'm guessing? Hopefully this is a fairly standard system, with hi/lo ports, etc. No trouble codes from IID tool. Need to address this before it really heats up. Also, anything to check before taking it in? Thanks a lot!

If it was low Freon you would get A code from the IID tool. Your most likely looking at a new compressor or condenser. I live in California so I already went through an a/c compressor. Funny story i actually went through two of them because my new one ceased up for a year and the shop did the compressor and an all new condense for free. Compressors are expensive, i hope that’s not the issue in your case but I wouldn’t be surprise.

Interesting, because it was working perfectly before the transplant. Hoping it's something stupid and simple.

When I was inspecting my current 2013 before purchase, it wasn’t blowing cold. The (non-LR) dealer took it back to the shop for a quick freon charge and it’s been fine ever since. You are right to start with the easy stuff first.

After an evacuation, leak test and a 2lb refill(all using this fancy Snap-On machine), we are back in business. Not sure what happened but let's hope it stays working!
