I got rear heated seats and my car was pre-wired so I was able to connect them.
Then I got the wires for the switches from under driver's side carpet.
I see that Relay 1 in the trunk is responsible for rear heated seats.
I tried swapping relay 2 and relay 3 into the relay 1 slot.
When I push on the switch, it only illuminates for a second and that's it.
Anybody had that happen?
