Need Help! Rear AC not working in my 2017 Chevy Traverse

I’ve been having trouble with the rear air conditioning in my 2017 Chevy Traverse and I’m hoping someone can help me troubleshoot the issue. The front AC works perfectly, but the rear isn’t blowing cold air at all, and I’m not sure why.

What I’ve Tried So Far:

  • Temperature Settings: I’ve checked that the rear temperature settings are set correctly, and they seem to work fine.
  • Vents: I’ve made sure all the rear vents are open and not blocked.
  • Fuses: I checked the fuses related to the AC system, but they all seem intact.

Additional Details:

  • Mileage: The vehicle has about 70,000 miles on it.
  • Other Symptoms: I’ve noticed a faint smell coming from the rear vents sometimes which makes me think there could be an underlying issue.

Questions:

  1. Is there something specific I should check next?
  2. Could this be a common issue with this model?
  3. Any DIY fixes I can attempt, or should I take it to a mechanic?

Seeking Any Advice:

I’d really appreciate any guidance or tips from anyone who has experienced this issue before. Thanks in advance for your help!

Have you checked the rear blower motor? It may be faulty or have a bad connection. That could explain why the rear AC isn’t working.

That’s a great point! I would also consider checking the fuses related to the rear AC. Sometimes it’s the simplest things that cause the biggest problems.

Exactly! A refrigerant leak can be sneaky and tricky to find. It’s worth getting checked out ASAP.

I had a similar issue the other day. Turned out the rear AC control module was faulty. Have you considered that area?

Sometimes, wiring issues can also cause the rear AC to fail. It’s worth checking the electrical connections for any damage or corrosion.

7

True! The last time I faced AC issues, it turned out to be a wiring nightmare. Always check those connections closely!

What about the AC compressor? If it’s not engaging properly, the rear AC would likely not work either. Just throwing another option out there!

I think it’s also important to consider the temperature settings. Sometimes it’s set incorrectly, or the climate control system needs recalibration. Just a thought!

Good call! That would be so easy to overlook. Always double-check those settings before diving into repairs.

I’m betting on a refrigerant leak too! It’s a common problem, and honestly, who doesn’t love spending money on repairs? :joy:

It’s true that AC repairs can be a real pain! Just remember, though, sometimes these issues can be fixed simply—like those pesky blown fuses.

Thanks, everyone! I’m going to check all these suggestions. Hoping it’s just a simple fix because I can’t stand the heat back there!

I feel your pain! Start by checking the rear AC fuse. It could be a simple fix if it’s blown.

Great idea! Also, make sure to test the rear AC controls. Sometimes they can be stuck or malfunctioning.

Have you checked the blower for any blockages? Leaves or debris can easily cause issues.

Exactly! I had a similar problem and found some leaves in mine. It’s surprising how much that can affect airflow!

Before going further, you might want to test the AC with the front controls. If the front works, it’s likely a rear unit issue.

Good call, daniel26! Plus, don’t forget to check the refrigerant levels. Low levels can cause the rear AC to stop working.

A quick way to check is to look for icy buildup on the lines. If you see that, it could indicate low refrigerant.
