Check for any error codes using an OBD-II scanner. Sometimes there’s a diagnostic code that points directly to the issue.
Those steps sound good! But if all else fails, reach out to a professional. Better safe than sorry.

Totally agree! But let’s hope it’s just a simple blockage or fuse issue! You got this!
And remember, if you find a way to fix it, maybe you’ll become the Rear AC Whisperer! 
Maybe I’ll get a t-shirt made! But really, thanks for all the advice, everyone. It helps to hear different perspectives.
Reflecting on my own experience, it’s easy to overlook simple fixes. These troubleshooting tips might save a lot of trouble!
I had the same issue with my 2017 Chevy Traverse! It turned out to be a faulty rear AC blower motor. The part cost about $150, and labor was around $100 at a local shop.
Thanks for sharing that! Did you consider going to a dealership instead?
Dealerships often charge more for labor, usually around $150/hour! That’s why a local mechanic might be better. Just get quotes before deciding!

I didn’t! Local shops offered better rates and solid warranties. It’s worth checking them out.
I would recommend asking your local mechanic first. They’re often just as good and might save you money!
That’s good advice! Any specific mechanics you trust?
I had my AC fixed at Joe’s Auto Repair, and they did a fantastic job! Super friendly too. They charged me just under $200 for the fix.
That sounds great! What specific issue did you have?

It turned out to be a clogged drain tube. The tech explained it was a common issue for that model, so it’s worth asking about that if you’re having problems!
That’s helpful to know! I’ll definitely mention that to my mechanic. Thanks!

If you want to save money, DIY repairs can work if you’re handy! Rear AC components can sometimes be found for much cheaper online.
Are there any specific parts you’d recommend looking for?
For me, the blower motor was relatively easy to install. There are plenty of videos online that can guide you through it!
