1999 mercury sable heater not blowing hot or cold air


If no blower is running check for a bad fuse for the heater blower or a bad blower motor and or resistor or burned connector to the blower motor

2002 Merc Sable wont blow air


I'd have to say it's the blower motor. Does it blow hot air when the heater is on?

I replaced the thermostat, but it still blows cold air. What gives?


The ford taurus and mercury sable are very well know to have coolant pressure, heat problems. I have worked on a minimum of 300 of these specific vehicles in my career, I can tell you the system is a headache,yet manageable. Are you getting cold air through the vents? is the blower motor working? Is your antifreeze brown in color or goo like? (a tell tale sign of a broken water pump and 90% probability of a clogged heater core.
also other basics, have you flushed the system and checked to make sure the car is not air bound?

I have a 2002 mercury sable that heater will not get hot. last year replaced a stopped up heater core and it was fine all winter. this year replaced thermastat and blend air actuator. its warm but not...


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

No heat. gauge working. fairly new thermostat. replaced engine, radiator cap.?


I am guessing that the gauge is showing normal operating temp, if so, I am also guessing that the blower motor is pushing air through the ducts.... if so than

were heater hoses reconnected ?
was hot water valve vacuum line reconnected ?
was all air purged from entire cooling system after engine repplaced ?
were heater hoses connected properly to get correct direction of flow ?
are hoses to heater core under hood getting hot ?

is the heater core clogged ?

Hello. You are in luck. I just had this same issue in my shop this week. We changed the thermostat, and replaced the coolant. Fixed it right up. Since you did not mention a new thermostat, that would be my next move, if I were you.
