Honda Clarity AC Woes: Warm Air Despite Settings?

Insufficient Cooling/Heating

|

Air conditioning blows warm air

Hey everyone! Having trouble with my 2012 Honda Clarity EV (207k km). The AC's acting up, only getting warm air and the overall cooling/heating performance is really poor. I've got a feeling it might be the ambient temp sensor playing tricks, but I'm hesitant to visit a mechanic after a recent bad experience. Has anyone dealt with similar symptoms in their Clarity? What was the actual issue and how much did the repair cost? Thanks in advance for any insights!

Hey there! I've got a 2015 Honda Insight EV and ran into a similar issue last year. The symptoms were identical, inconsistent temperature control and mostly warm air coming through. Took it to my trusted mechanic and it turned out to be a faulty ambient temperature sensor connection. The cable had worked itself loose over time and was giving incorrect readings to the climate control system. The fix wasn't particularly complex, they had to remove some trim pieces to access the connection point, clean the contacts, and secure the plug properly. Not a serious repair at all, but definitely something that needs proper attention since it affects the whole climate control system. Just make sure whoever checks it uses the right diagnostic tools, these EV climate systems are quite different from regular cars. Would suggest getting it looked at soon before it potentially affects other connected systems. Hope this helps with your decision!

Thanks for sharing your experience! That's really helpful and sounds exactly like what I'm dealing with. Quick question, do you remember roughly how much you ended up paying for the fix? Also, has everything been working smoothly since the repair? I'm trying to get a sense of whether this is likely to be a one-time fix or if I should expect other issues to pop up.

Hey again! Yes, absolutely, happy to update you! I got it fixed and it cost me 95€ in total, which covered both the diagnostic work and fixing that pesky cable connection. To be honest, given how much the faulty sensor was messing with my comfort, it was totally worth every cent! Since the repair, my climate control has been working like a charm, everything's back to normal. The AC blows nice and cold when I want it to, and the heating's spot on too. Such a relief not having to deal with those unusual temperature swings anymore! The mechanic explained that once these connections are properly secured, they rarely cause problems again. It's been over a year now, and I haven't had a single problem with the system. The key was getting it diagnosed correctly, turns out that loose sensor connection was throwing off all sorts of incorrect readings. Trust me, you'll notice the difference immediately after it's fixed. No more second-guessing if your AC is working right or not!

Thanks so much for all the details! You've convinced me to get it checked out. I actually took it to my mechanic yesterday, and wow, what a difference! Turns out it was exactly what you described, a loose sensor connection. Cost me a bit more at 120€, but totally worth it. The funny part was when the mechanic showed me the old connection, it was literally hanging by a thread! He fixed it up in about an hour, cleaned everything, and now my AC's blowing perfectly cold air again. Such a relief after sweating it out for the past few weeks! Really glad I didn't let my previous bad mechanic experience stop me from getting this fixed. Should've done it sooner, honestly. Thanks again for pushing me in the right direction, you saved me from potentially bigger problems down the road!
