Had a quick search but couldn’t find anything that really described what I’m hearing from my climate control.

 

I’ll start the car up and hear what’s best described as a suction sound for about 3 second from around the bottom of the windscreen.

 

It’ll randomly happen again in the middle of a journey.

 

As far as I can tell the climate control works fine. It’s always left in Auto with A/C.

 

Last had the aircon serviced about 2 years ago, most recent car service was Feb with nothing mentioned.

 

I don’t recall how long it’s been going on for and as I’ve had no ill affects it’s not bothered me. Just curious now.
 

Any thoughts on this?

Sounds like mine did when the aircon gas was low. Might be worth getting the levels checked.

What happens if you turn it off and then leave it off. Start the car, and then turn it on? (so it's not on automatically at start up)
