I’ve been trying to get some heated seats on my jeep rigged up to a 3 position switch with two different LEDs to show me warm or hot. The LED’s light up but the seats don’t get warm. They seemed to work ok before I had the LED’s on.
One cause might be that when I first did this I had the seats connected to the NC side of the relays not the NO side as shown. So it could be that the double power to the seats blown their circuit??
Can you see what’s wrong here, am I shorting out with the LED or something else?
