Fan won't switch from defrost to other settings

Hey guys,

My interior fan won't switch from defrost to any of the other settings. Is this just an electrical issue? Any idea how to fix?

Thanks!

Sounds like you have a vacuum leak.

Check the small white vacuum line in the engine compartment (it likes to rot out). Cheers!
