Default HVAC controls

Quick question.

Ive been looking at a few things on the HVAC and working on things when i noticed something. Every light on the control panel including the off button turns green when i select that option.

except....
the defrost and the rear defrost elements. (the far right 2 buttons on the pad)

Those always light up orange. Jus tkinda struck me odd that they were a diffrent color. I can see the redefroster being diffrent but the front ones. Just odd and didnt see anything in the owners manual for it. I havent looked through the service manuals as of yet thou.

My manual says to use the defrost when you use the rear defrost, maybe that's why they are the same color?

when all lights come on it may be time to replace it or at the very least disassemble carefully and clean all the contacts that make contact with the control buttons....
