Seeking Solutions for Poor AC and Heating Performance in 2015 Renault Thalia/Symbol

Hey there! Sounds like a familiar problem. I had a very similar issue with my 2013 Renault Wind. I'm no mechanic, my auto skills are kinda limited, but the local workshop was super helpful with this. It turned out to be a defective electric auxiliary heater, just like you suspected for your car. They sorted it, cost me about 350€, which seemed fair. Maybe check your ThaliaSymbol with a reliable mechanic, could be the same issue. If it is, it should be affordable to fix. Also, could you share more about the issue? Things like when the problem occurs, if there's noise, etc. might help narrow things down. Good luck!

Hey, thanks for the speedy reply! Interesting to hear you've dealt with something similar on your Renault Wind. I'm yet to take my Thalia/Symbol into a local garage, but I'll make sure to get it checked out for the heater component as you suggested. More details on my side, the AC and heater conk off intermittently, sometimes during a long drive, sometimes just after a few kilometers. There is no weird noise or anything - it's super quiet which is unnerving. By the way, the car's mileage is 58742 KM, and I had the last service around four months back. I don't remember them mentioning anything about a potential problem with the climate control system though. I'll definitely follow up with a trusted mechanic and see what they can do. Thanks for your help! Appreciate it.

Hey again! Your situation does sound pretty similar to what I went through. Considering the issue happens intermittently and there's no weird noise, an electric auxiliary heater problem does seem likely. Sometimes it's just a small electrical issue or a worn-out component causing the problem. On my Renault, it was also doing its thing off and on, and there was no noise when it fuzzed up. Your car's relatively low mileage and its recent service should put most big issues out of the equation, but components can fail without any warning, Happens! Don't worry too much. As long as you consult a knowledgeable mechanic, you should be able to nip this in the bud. Let us know what your trusted garage comes back with, fingers crossed it's minor and quick to fix. Oh, and if you had a full service four months ago with no issues, possibly no one checked the car's climate system or maybe the problem hadn’t presented itself yet. These things can sneak up on you, you know. Always a good idea to check the service manual and confirm what's checked during regular services. Good luck! Let's hope it's a straightforward and affordable fix, like mine was with the Renault Wind.

Hey there again! Definitely some strong similarities with your scenario and what I went through with mine. The intermittent funkiness and the lack of unusual noise is indicative of an issue with the electric auxiliary heater, to my mind. It could just be down to a minor electrical problem or a component reaching the end of its useful life. My Renault was behaving in much the same way - working one day, then not the next and never making a peep about it. The fairly low mileage and recent servicing of your vehicle should rule out most major problems but, you know, sometimes these things just fail without a clear reason or warning. It happens! I wouldn't be too concerned if I were you. As long as you're getting a competent mechanic to take a look, you'll surely get to the bottom of it. Do let us know what your trusted garage suggests. We're all hoping it's something minor, easy to fix and on the affordable end of things. As for your recent service, perhaps they simply didn't inspect the climate system, or the problem wasn't evident back then. Some issues can just sneak up on you! I'd recommend having a look at your service manual and checking what's supposed to be assessed during regular servicing. Alright then, all the best! Looking forward to hearing that it's just a straightforward, not-too-hard-on-the-wallet job like it turned out to be for the Renault Wind.
