Seeking Advice on Troubleshooting 2007 Fiat Multipla's A/C Issues

Hey there! Sounds like we've got a similar issue here. I've got a 2005 Fiat Brava that had the same problem a while back. I'm by no means an expert, but I have a fair bit of experience tinkering with cars. Found out the issue was with the air conditioning control unit, it was defective. Took the ol' girl to my local workshop and they managed to sort it out for me. Cost me a bit, 980€ to be exact, but my A/C's been running smooth as silk ever since. But hey, each car can be a different story right? Can you share a bit more about your engine, mileage, and any unusual noises or smells when you try to run the A/C? It'll help me to give a bit more specific advice. Keep me posted!

Hey! Thanks for your insights. Sorry, I should have mentioned my engine and mileage earlier. My Fiat has gone about 191460 km, and the last service was not too long ago. I didn't notice any strange sounds or smells when I try to turn on the A/C, it's just the lack of cooling or heating. It's like it suddenly lost its mojo. Your experience with the A/C control unit seems like a plausible cause to me. Maybe it costs a bit, but the thought of having back the breezy, chilled air, and warm vibes in cold weather is worth it. I'll check in with my local workshop and see if they can work it out. Again, appreciate your help! Cheers!

Hey! No problem at all, glad to help a fellow Fiat owner. Yours has clocked quite a hefty number of kilometers, so it's not unfeasible to think it might be an A/C Control Unit issue considering the age and mileage. Definitely get it checked out by a professional. If it is indeed the control unit, the cost might seem steep, but believe me, it’ll make a world of difference. I remember driving in the peak of summer with no A/C, it was like being stuck in a giant sauna! If the control unit isn't the issue, they should be able to help you suss out what else might be going wrong. It could be something as simple as needing to re-gas the A/C system. That’s definitely cheaper but remember it's a short-term fix, and you might find yourself back where you started after a while. Do keep me updated! Looking forward to hearing that your Fiat is back in tip-top shape. Cheers!

Hey again! Dude, you've been such a big help! I can relate to the giant sauna feeling; I don't want that, especially with summer approaching. I've scheduled an appointment with my local workshop for tomorrow. I mentioned your insights about the A/C control unit to them and they'll definitely check that out. If it's as simple as re-gassing the A/C system, I'd be relieved although I know it might be a temporary solution. Can't wait for my Fiat to be back to its cool self. I'll keep you posted about the outcome. Until then, thanks for your precious help and advice! Cheers!
