1995 Honda Civic

Hi, So I'm wonder'n, is the blower motor work'n at all? Is that what you mean? Spd. - 1-2-3-4? If it not work at all, it may be a fuse. I think fuse for that in inside car fuse box, but there is another fuse box under hood. If fuse o.K., There is a rheostat mounted on blower motor case under B-Hind glove box. If this is not what you mean, & you are talk'n about the temp. Control, ck. Temp. Knob, pull it off & ck. Inside knob at the center for a break or crack. Ck. Temp. Cable & Hot-Cold valve under hood where hoses come through firewall from heater core. It may be seized.
