I recently installed boost tow mirrors on my 2020 STX. I went up to switchback, but haven’t hooked the switchback cable up yet so just turning signals work. For some reason my AC isn’t wanting to work all of a sudden. Could any of that be related? Maybe I blew a fuse?? Or just random? Lol

 

I bet you didn't disconnect the batt, did ya? So, what you need to do most likely is disconnect your negative, turn lights on, let truck sit for 15 minutes, then turn off lights, reconnect batt, this is also called a KAM reset. Hopefully all will be normal. These trucks with all the electronics do stupid, seemingly unrelated things, many times when doing electrical on them.
No guarantee, but likely.
Did you get the wireless folding option too? I just installed those TT mirrors, but I disconnected the batt before hand.

 

Do the boost mirrors have the temp probe on the underside?… is it hooked up? If the probe is not connected… your a/c won’t function.

 

Mine came with it installed and wired correctly, mine is a 2020 as well.
Boost says if your truck came with it, the new ones will too.
