Overheating 2021 Nissan Sunny with AC Issues: Suspected Electric Fan Failure

Hey there! I had a similar situation with my 2018 Nissan Sentra, so can totally relate to the struggle. My AC also started feeling like a portable heater and my engine was hot as a volcano. Turns out, it was indeed the electric fan that caused the problem. The diagnosis was made as a "faulty control unit/resistor." I had to replace the control unit/resistor for the fan. The job wasn't too complex but necessary due to its role in managing the cooling system to prevent overheating. It's not just about comfort, it's more related to your engine's health. So my advice, don't compromise. Get to a reputed garage and have them look into it, focussing on the electric fan's control unit/resistor. Heat can be merciless on car engines. Stay cool!

Hey, thanks for sharing your experience, sounds pretty similar to what I'm dealing with. Do you remember roughly what the damage was to your wallet for the control unit/resistor fix? Also, have you had any other issues crop up since then? Cheers.

Hey! Good to hear from you. Yeah, so the fix for the electric fan's control unit/resistor set me back around 480€. It was a bit of a bite into the wallet, but honestly, it was worth every penny to get that desert breeze in my car turned back to a cool, comfy chill. Since the repair, the car's been behaving itself pretty well. The overheating issue was sorted right away and stayed that way. My mechanic did a neat job. Haven't noticed any other sneaky issues creeping up either, so it seems like the repair really hit the nail on the head. Keep in mind though, a good mechanic is key! All the best with your Nissan Sunny. Hope it chills out soon! Stay frosty!

Hey, that's reassuring to hear! 480€ does sound hefty, but you're right. Engine's health comes first. I cannot drive my wheeled oven longer. Even more encouraging to know that the fix got you the chill back and that the overheating was put in check. Let me look up a mechanic based on reviews then. Fingers crossed I don't run into any more trouble. Thanks a ton for your help! Keep cool! Cheers.
