AC Issues: Eclipse Cross Won't Stay Cool, Fix Needed

Hey there! Had a similar issue with my 2017 Mitsubishi ASX Diesel last summer. The symptoms were exactly like yours, warm air and inconsistent cooling. Took it to my regular workshop, and it turned out there was a refrigerant leak from a cracked seal. They had to evacuate the system, replace the seals, and recharge it with fresh refrigerant. The whole thing cost me €495, but it's been working perfectly since then. Can you share some more details about your Eclipse Cross? Like the mileage and if you've noticed any other symptoms (weird noises, moisture under the car)? Might help pinpoint if you're dealing with the same issue.

Thanks for sharing your experience! My Eclipse Cross is at 68235 KM and just had its service last month. I haven't noticed any moisture under the car, but there's a slight humming noise when the AC is running. The cooling issue started about two weeks ago, and it's been getting progressively worse. Your refrigerant leak situation sounds similar, I'll definitely get that checked out. Was your repair done at a Mitsubishi dealer or an independent shop?

Hey again! Yes, I remember helping you out with your AC issue. For my ASX, I actually went with an independent workshop, Auto Tech Solutions. They're certified for Mitsubishi repairs and their prices are way better than the dealer's. Plus, they've been maintaining my car for years now. That humming noise you mentioned, I had that too! It's actually what made me take my car in before the AC completely failed. In my case, the humming was related to the refrigerant leak putting extra stress on the compressor. The good news is that we caught it before it caused any damage to the compressor itself, which would've been way more expensive to fix. Just a heads up, if your symptoms are getting worse like mine did, don't wait too long to get it checked. I learned that these issues can snowball pretty quickly. The independent shop I went to did a pressure test first (cost about €75) to confirm the leak before doing the full repair. Might be worth asking your shop about that as a first step. Let me know how it goes! Always happy to share more details about my experience if you need them. These Mitsubishi AC systems can be tricky sometimes, but they're usually pretty reliable once fixed properly.

Thanks so much for all the detailed info! That's really helpful about Auto Tech Solutions, I'll definitely look into independent workshops in my area. Good to know about your humming noise experience too, makes me feel better about catching this early. I just called a local certified shop and they can do a pressure test tomorrow morning. You're right about not waiting, don't want to risk damaging the compressor. Will update the thread once I know what's going on. Really appreciate you taking the time to share your experience in detail. It's always better to learn from someone who's been through the same thing!
