Air-con not working?

[Toyota3000]

Hi all

I hear a click when it's switched on but there's no change in temperature. Anyone know what the solution could be?

Thanks.

Had similar on an Avensis, it needed re-gassed.

Also check the relay,it's in one of the fuse boxes under the bonnet, the diagram inside the lid will give exact location

After that you really need someone  who knows what they're doing to take it further.
