Weird sound at temperatures below 32 degrees F

[Ashr]

This has been happening since yesterday morning as soon as I unlock the car door! It lasts about 5 seconds and only happens at temperatures below 32 degrees F and when the engine has been sitting for a few hours!!

Wow, cold weather certainly introduces some strange noises in cars, but that isn't a normal sound, and doesn't sound like a belt. Sounds more like a pump of some sort (fuel pump priming?) or you left your dog in the car overnight! Good luck in chasing that down and report back on what you find. Good luck.

Ashr - Since I don't knowhow to quote previous posts yet, check this thread from @Brojave22 last Wed at 10:14. " its in the high 20s low 30s here, when I cold start the 2022 mojave gas, it makes a pulsing pump sound maybe 4-5 times then goes away, doesn't seem to be affecting anything but just want to know what it is and is it an issue. coming from pax side in the engine bay, its very subtle, any ideas?"
