Sister/husband has a 2002? Acura MDX. They got in to go to work this morning and NO air blows from the front vents/defrost.......nothing. They only have rear controls working.

Thoughts? I'm looking at fuses first, after that I'm kinda brain dead...........play with controls see if there are any noises leading to something but from what she said it just sounds dead.

Time to go check it out.........thanks!
