Hey,
After getting my car serviced, the A/C stopped working. I checked under the hood and noticed an unplugged cable, but I'm not sure where it's supposed to go—or if it's even related to the aircon. Could someone help me identify it or point me where to plug that?

 

The second photo looks to me like an O2 sensor connector…

 

In the end, it turned out to be the cable to the A/C cut-off switch—it was torn and needed replacement, which is why I couldn’t see where to plug it in. thank you for help!

 

Had that happen after a service once—turned out a connector for my compressor clutch had been left loose. It looked random, kind of like an rca to rca cable hanging there doing nothing. If yours has two pins and is near the A/C lines, it might be that. I’d trace it back and see if there’s a matching plug on the compressor or nearby bracket before running the car too much without it connected.
