I have a 93 accord lx and when i bought it everything worked perfectly, but now the climate control doesnt work.

WHat works:
fan speed
heat/cold ****
AC button
New Air Button
Recirculating Air button

What doesnt work:
directional button: to feet, defroster, etc

yeah yesterday i had to keep wiping down my windows with an old shirt to keep the moisture off cause defroster doesnt work.

do you think it si just a fuse? and if so which one?
