My AC button won't stay ON!
 

Hello Fit people! I'm having issues with my AC button that is defogger too, the compressor will come on when I'm pressing the button but as soon a release the AC button shuts down AC compressor...

Do I need to replace the entire button??

Yes, and you can get a cheap one on eBay or aliexpress. Good luck changing it out!!
There's a guide here in the forum on the process of swapping it out.

Or you can get one from a DIY salvage yard.
