Cruze has 42k miles on it. The last 3 days in a row my car overheats while idling in heavy traffic. It did this with a/c off. Car went back to normal operating temp once I was moving. Any thought to what part is going bad?

A/c off warning light and idle engine warning light.
Coolant level is normal; no leaks.
1.4 engine
No engine fan running when temp peaks.

The fan spins by hand but I haven't seen it move otherwise

I tried running A/C with the hood up. Fan still isn't moving.

I tested 46 fuse; it's still working. I tried running A/C again and the engine fan is running now. I took a pic of the coolant tank. Is this full or do I need to put it to the top line? There is an up arrow at the top line. My coolant is the middle line.

I was finally able to replicate the issue by idling at 220-225/normal operating temp and having someone rev the engine slighty with the A/C on. The temp began to creep up to 240/middle line on the gauge.

There was alot of clicking sounds, which we assumed was the car trying to turn the fan on, but the fan never came on.

Thanks to all that pointed this out and the reminder that I can review engine temp in the lcd driver screen. Hopefully my extended warranty will cover the repair.

I took the car in. Repair was covered by extended warranty. It was the radiator fan itself.
