i can't figure out where my cruise control went. nor can i figure out why i get all kinds of air through the dash vents when i've got the control shut off. or why, when i set the control to blow on my face, it comes out of the defroster. and when i ask the defroster to blow, it sometimes in my face. i've checked all of the little vacuum hoses i can find, and i don't believe i've knocked any of them off... help me, please!!:{
