Question about 2001 Mercury Grand Marquis
If the heater hoses are hot on both sides(indicating the engine is at full temp) and you feel the heat controller in dash is working properly, i would suggest disconnecting both heater hoses and backflush heater core with decent amount of pressure. if this improves condition but does not solve completely, heater core replacement is necessary.
