Air con problem

No cold air, but all dash controls functioning. Fault reader shows B1B78 - system pressure - signal is below allowable range. Looks like a re- gas required. Would someone please confirm.
Further, the air con compressor does not seem to click in when air con switched on - could this be a fuse or relay, because I can't find one yet.. Many thanks.

Correct - you'll need a leak test when you have it gassed.

Thumbs Up
