aircon not working 156 sw

my aircon has stopped working the light wont come on.
had it re-gassed no problems.
forced the compressor on and cold air comes out.
checked fuse ok

strange thing is that there is suppose to be a aircon relay in the engine bay but its not there and no connector for a relay.

the car is a 03 pre-face lift but with face lift interior

Anyone any idea where the aircon relay is?

i think the relay is under the dash on passenger side with the climate control white box but maybe wrong.
but the problem maybe the switch as i think ive read a few threads on it while ivebeen looking for stuff

Is the outdoor temperature measurement function correct?
Do it show the right temperature in the center display?
Because if the outdoor temperature is too low the compressor is not engaged and if you car is a facelift version with dual-zone climate control the light wont come on.
If the temperature sensor in the mirror is open circuit or have an increased resistance this will be measured as a very low temperature and the climate control wont engage the compressor
