I will start off by saying that I know the air conditioning is not great, but I would just like to get it working!

I'm not getting power to the compressor and trying to locate the relay (I believe I found the fuses and they are fine).

I see two yellow relays under the seat box that should be for AC but the wiring doesn't seem correct for the compressor.

Also, does anyone know if the harness behind the air condition ducts has a connector that would specifically power on the compressor? I am thinking it should and perhaps something is not plugged in.

And yes, the system and compressor works fine with 12v hooked up directly to the compressor.

Thank you, in advance.
 
A/C relays on my defender are under the drivers seat in the same cubby box as the ECU. In the picture taken looking into the under seat cubby from the open drivers door and counting the relays from the left, Relay number 3 is for the air-con electric fan under the bonnet and Relay number 4 is the air-con compressor clutch relay.

I know this because having removed my air-con I now use the leccy fan for my normal radiator and the air-con compressor is ear marked for on board air when I get round to it.

Thank you, I appreciate it.

If one of the plugs in the harness was disconnected I would think the entire unit wouldn't turn on but I guess it is possible it would just keep the compressor off as well.
 
Yes, with 12v directly hooked up to the compressor it blows cold.

It is just an issue with power getting to the compressor.
