I just installed an new radio, 98 Honda civic, every thing works perfect with the radio but the climate control only blows from the front of the dash and when I push the floor board or the top of the dash to make it blow from there it doesnt switch to either. It does blow but does not allow me to switch from one to the other. the lights work on it also. Ive tried looking under neath to see if anything is turning or moving when I push the buttons and nothing happens. The button that makes it so fresh air circulates works, when I push it, the lever opens and closes when i push it again. Could it be a fuse or relay?
