Hi.
I have problems with my AC/Clima. Not turning on.
Clutch - Do not engage.
A quick test with12 volt+ directly to clutch - still not working.(That is one issue)
A manuel test of the relay = OK
Relay in fuse box = Not working....
The fuse i OK
The main-wire from fuse box is yellow/Green but this wire is not present at the AC Compressor.
Present wire at compressor is White/Brown.

What am I missing?

I so badly need a diagram of this system. Hope you can help.

Here's a wiring diagram for a 4 cyl. (don't know what engine you have) Many things can stop the compressor from turning on. Outside air temp, evap air temp, engine temp are just three of the parameters that can control ac relay/clutch operation. Note the ECM grounds the relay to energize the clutch. You might start with a compatible scan tool that can talk to all the control units in the car.

 

Thanks... Really appreciated.

More to do tomorrow!
