Gurgle and Whining noise when switching CC off
« on: 13 February 2009, 14:10:53 »
I notice that whenver I switch off my Climate Control there is an electrical whining sound for about 5 seconds followed by a gurgling noise(like water boiling) for about 3 seconds.

Might this be trapped air in the system and/or something else?

Any suggestions welcome!

Sounds like air in the heater matrix.

Try running the car, heaters on hi, and expansion cap off
possibly also burping pipes to try and free any air.

Thanks - do you take the cap off and then start the car? Won't water spill over?
- forgive my ignorance but what is burping the pipes?

it will, if the car is hot, as it will be pressurised.
If started from cold it wont, or removed slowly and carefully when hot, should be ok

burping is just giving any hoses a squeeze really.
