Mitsubishi 380 AC Failure: Common Sensor Issue?

Hey there! I had a pretty similar issue with my 2005 Mitsubishi Galant (I have some experience working on cars but nothing too fancy). The symptoms were exactly the same, warm air and wonky temperature control. Took it to my local workshop and turned out it was a faulty sensor cable that needed replacing. The whole thing, including labor, cost me around 95 Euro and fixed the problem completely. The mechanic explained that these lines can wear out over time. Quick question though, have you noticed any other electrical issues, like flickering dashboard lights or inconsistent temperature readings? This could help pinpoint if we're dealing with the same problem. Also, does your check engine light come on? Let me know these details and I might be able to help more!

Thanks for sharing your experience! Yeah, my situation sounds pretty similar to what you described. I'm at 121151 KM and had my last service about two months ago, but this issue just started recently. Actually, now that you mention it, I have noticed the temperature gauge acting a bit weird lately, but no flickering dashboard lights. The check engine light isn't on either. Your repair costs sound pretty reasonable, definitely beats driving around without AC in this weather! I think I'll get it checked out at the workshop this week. Really hoping it's just a sensor cable like in your case.

Hey again! Thanks for those extra details about your Mitsubishi 380. You know, after I got my Galant fixed, I remembered something that might be useful, before the sensor cable completely failed, I also had weird temperature gauge readings without any other electrical issues, just like you're experiencing now. Just to share a bit more from my experience: after they fixed the sensor cable, I've had zero issues for about 2 years now. The mechanic also recommended checking the AC filter while they were at it (ended up being pretty clogged in my case), and it made a huge difference in the overall AC performance. Given what you're describing and the mileage on your car (mine was around 125,000 KM when I had the issue), it really does sound like the same problem. The fact that it started suddenly and you're not seeing any check engine lights matches my situation exactly. Quick tip: when you take it to the workshop, maybe mention the temperature gauge behavior, that's what helped my mechanic diagnose the issue faster. Keep me posted on how it goes! Really curious to know if it turns out to be the same thing.

Thanks so much for all the detailed info! It's really helpful to know about the AC filter too, I'll definitely mention both that and the temperature gauge when I take it in. Actually just called the workshop and got an appointment for this Thursday morning. It's such a relief to hear that your fix has lasted for two years without any issues. The fact that our cars had such similar mileage when the problem started makes me pretty confident we're dealing with the same thing. I'll definitely let you know how it goes after Thursday. Really appreciate you taking the time to share your experience, it's made me feel a lot better about getting this sorted out! Thanks again for all the help!
