Dear 2CarPros, can you help me? i need wiring diagram for 2011 Ford Mondeo 1.6 tdci econetic.

My problem the A/C compressor wont turn on. i'm now buy this car. check the gas level, is not enough. filled up.
Compressor don't start.
Check the button - okay.
Check the relay - okay.
Check the fuse - wrong (replace) not working the compressor.
Check the compressor two wire ( coil ) to earth, okay no problem.

i'm try check compressor 12 volts on connector. but failed. i don't know no 12 volts to compressor or problem via multi-meter.

Any idea? can you send wiring diagram for this car?
