If the thermostat on a 1996 Ford Windstar has been replaced but it still only blows cold air and the gauge rises above half when sitting still what could be wrong?

1992 gmc truck that won't warm up The radiator cap thermostat and coolant have all been replaced The system was bled twice?

All I can think of is you got a defective or the wrong thermostat, because as far as I know the only thing that regulates the temp is the thermostat. Also if anything else in the coolant system was bad you would usually have a over heating problem. Have you tried touching the heater core hoses, If the heater core is cloged usually only one hose will be hot because the core is plugged and not lettig coolant flow thru in and out. Do you have a heater control vave that could be stuck?
