Rear heated seats

[80stech]

According to the wiring diagram (you have Benltey manual right?) the rear seat heaters get power from the unloader relay. Green/white wire to the rear seat htr switch.

I haven't checked the relays. I I will see if any next to it are the same and try swapping.

I saw this on here, I will double check the bentley manual also.

Use the relay from the rear window defroster next to the seat heater relay to test. They are the same.

That picture is correct, the missing relay is the one you need to have.

Ok guys. Swapped the rear seat heater relay with the rear window. No dice, still no heat on the rear seats. What gives?
What else can I try?
