I have a 1993 SC400. My heater will blow but not warm air. Is there a heat control valve that I can check/replace or should I be looking for trouble someplace else ?????? Is it controlled by a fuse or what ??

No, I don't get hot air when in motion. I changed the thermostat like SeanGrac said. It made no difference. I am now looking for the heater valve, with no success. Is it on the firewall section (passenger side) or on the fender weld (passenger side) ????? I've checked all fuses and they look good. Still stuck !!!!!! Thanks
