LED
The heater relay only activates when the fan is on and the heat setting is selected.
The LED only comes on when there is actually current going to the heating element. So, if the 144 system is switched off, the LED will not come on even though the relay is closed.
I now have two new LEDs on the dash. The top LED, red, indicates the motor is overheating. The second LED, orange, is the heater LED.
The heater does not seem to use much power. I guess I will find this out tomorrow.
