aircon probs.

Ok it's that time of year again - tried the aircon - zippo.
The compressor clutch isn't clicking in, thought ah! needs gassing up.. (low
gas switch)
Had it checked NO! it's got gas in.
I'm wondering about electrical probs as the drivers side electric window has
also recently packed in.
I've checked all the fuses in both boxes they're all fine, although
interestingly the fuse key in the handbook bares no resemblence at all to
the actual fuse boxes layout.
I'm thinking maybe hidden relay somewhere?
Has anyone seen anything like this?

cheers

No go on the aircon is almost always no gas or low gas pressure, although
you may have some gas the pressure may be too low for the gas pressure
switch so the compressor clutch solenoid does not come in. Try electricaly
bypassing the pressure switch, if the clutch then clicks in you need more
gas.
