Hey guys!

I was trying to see if one of my girlfriends fuses had blown (both tail lights don't work-fuse was okay though!?!?) and I noticed that her secondary air pump fused had blown. I can't find any information online about what this is and how important it is. I know her AC doesn't work anymore - does it have to do with that?

Thanks for your help!!

 

secondary air pump has 2 do with emission is ur check engine light on
