So my rear defroster does not work. When I push the button the led does light up but it is orange...not green. I can also hear a click when I toggle the switch near the fuse box. I looked for fuses for the defroster but can't find one specific. Is it a relay I'm missing? Please help. Thank you.

 

If you have the vehicle owners manual, it should , in the maintenance section, tell you which fuse/circuit breaker and relay are to protect the rear defroster system.

 

Are you getting battery voltage at the rear defroster??
If you are not then look for fuses
If you are then rear defroster is faulty
Check for resistance and look for broken lines
