1992 Land Cruiser AC Not Working

[ilovemy92lc]

So I have a serious issue. My AC does not work. Even when i press the AC button, no engine changes, no light comes on, nothing happens. It worked last year so I am dumb founded. If someone could help me that would be fantastic as it is HOT Outside.

The system shuts down if there is no gas pressure so the first thing to do is get it checked and re-gassed if necessary.

If that doesn't cure it, check the fuses.

Then I'm afraid its mechanical/electrical fault-finding.
