Heater doesn't work on 2002 Mercury Cougar

The heat in my car has stopped working over the last couple of winters. Last winter it took about 30 mins to warm up but this winter it wouldn't ever get warm at all. The AC works okay... not super well but at least it blows cool air.

Where does the temperature gauge read? If it reads on the low side of the gauge after 10 or 15 minutes driving I would suspect a bad cooling system thermostat. Check with the engine running /warmed up the hoses going into the heater core, both should be hot if the heater controls are on full hot, if only one is hot check the heater controls are operating the heater valve and or try flushing out the heater core with the hoses disconnected see if the heater core is restricted with debris. There are two companies that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have,much better than generic workshop manuals from parts stores and much cheaper than the factory manual try Alldata which is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online or Mitchell on line http://bit.ly/Mitchell1_Online_Repair_Manuals and get an online repair manual subscription.
