husband purchased a 90 taurus SHO, the last owner said that the heat worked but only got warm.. well warm does not describe it. it gets hot usually in the morning when started first thing, then when restarted throughout the day there is NO HEAT AT ALL. this doesnt mix well with leather seats let me tell you.. husband has replaced control panel, relays, heater switch. still nothing..
i need help, i work in a place with no heat and would at least like to drive home warm....

Have you checked the coolant level?

yes, is full, even flushed radiator and added new antifreeze. he is beginning to think about this heater control door you guys are all talking about, but is unsure exactly where it is, and what to look for..
