Driver seat heating problem

[0202224]

I have a problem with (V70 P3) seat heater. I have checked fuses in tailgate and replaced relay/control unit under driver's the seat with the passengers seat unit...still no heat. Can anyone tell me how to measure a heating wire in the seat? What is the correct resistance and which are correct wires/connectors? There is two gray connectors and one green connectors which are connected to the relay/control unit. I assume that wires from the green connector goes in the seat. If someone had wiring diagram it would be great help.
