My defrost button broke! How to fix?

Recently my defrost button broke and fell off. Can just the button be replaced? or do I have to get a whole new unit? Please Help

I just bought a complete dash. And have that switch if you need. Make an offer.

If you look in the teg tips, there’s a tip on how to fix the climate control lights/buttons. Following that, you could get the unit out to work at it at least. I’m not sure if you can actually buy the buttons individually or not.

Or was this the rear defrost button?

Oh yeah, is it jus the rear def button, or the whole heater/ac assembly. I have both, but am going to open up the spare to see how to make it light up amber. I am going to take it apart good so it goes back together and works again. So if you need one, make an offer.
