Here's another pic, just to help others ID the tabs on the relay board.

Here's a pic from the manual of the A/C circuit

And a closeup of the relay connections

Looks like you will definitely need some volts at the "+ 28 " pin, if the relay is ever going to activate.

It obviously shares voltages with the "G" pin so maybe worth moving one of the red wires to + 28 pin to test what happens.

You don't have to solder it, just disconnect then try with a jumper lead. 

Easy to move back if it doesn't make a difference. ^^^

yep, looks like its missing the +28v
the +28v supplies the voltage to the coil on the relay. so without that wire the relay can't energise.

going by the schematic there should be a wire from G to +28
leave the 2 wires on the COM and use a jumper wire from +28 to COM

that should fix your problem

using the picture you supplied of your A/C relay jumper a wire from the far right red wires (it looks like red to me) to the empty +28 tab which 1 tab to the left of the red wires. you could nearly blob some solder across the 2 contacts.
