    I have some heat when the fan is on low...turn it to high and the air cools down and so does the heater core outlet pipe. I'm thinking it's the thermostat or the heater core plugged

    I have the exact same problem. I find though if I rev the engine
    it starts blowing hot for a very short time.

    I just flushed the heater core, not much improvement.
    any ideas ---???

Its not a fuse if the blower motor works , you have a clogged or bad thermastat, bad water pump or your radiator heater core is clogged

It won't be the thermostat...Sable and Taurus have a design problem. The heater core hose going into heater core from water pump gets plugged up right at the heater core bypass junction. At Hardware store..Buy hard plastic hose/tubing about 4ft long that just fits inside of the heater core hose. My ACE hardware has white hard tubing. Cut one end of the hard tubing at angle to use it as a reamer inside the heater core hose. Now place the hard tubing on top of heater hose to measure the distance on hard tubing it has to travel up to firewall . Mark with black marker on hard tubing. Remove the heater core hose from top of water pump and slide hard tubing in hose all the way up to where the bypass connection is feeling the obstruction...rotating the hard tubing as you gently shove it thru heater core hose. Slide it back and forth and keep rotating it until you feel it go past the Bypass junction...10 min at least. Now take off the heater hose from engine on driver side that comes from the heater exit side...Use garden hose high pressure and back flush the crud out. Re connect hoses, add fluid to reservoir as needed. Or take to shop and have them do this. Many shops just back flush...Have them do BOTH! Buy the plastic tubing ahead of time so they have no excuse. I have been doing this on my 98 Taurus since 1999. Done many of these...You can also clamp off that bypass hose section with clamp or vice grips ..this will force all liquid to flow through heater core...remove clamp in spring! If you haven't changed thermostat for 4 years ...Change that as well. You tube has videos. Email me at davefudally@hotmail.com I promise you hot air...from the car!

My blower motor dosent work on my 2005 mercury sable


Probably your blower resistor switch (it's the part that gives you your fan speeds) is bad. You can test your blower by applying 12volts to it and see if it spins. The blower motor and resistor switch are both under/behind your glove box. Both should be easily accessible after removing panel above feet.

Heater blower won't come on


Could be the blower motor relay, the control panel on the dash, or the resistor.
You would need to check the blower motor for power and ground then work back to the fuse. I think the relay is in the box near the battery.

1998 mercury sable fuse box location for the blower


Your fuse panel should be located below and to the left of the steering wheel, next to the brake pedal. For the blower, you want fuse 13. It should be a 5 amp fuse.

Heater fan switch won't turn the fan on. I am missing the cover on the fuse box so I can't see which fuse would be the right one to change. Thanks Dan


just check all the fuses. if not take out fan and use a jump wire to see if it works and if it doesnt well you already have the job halve done. replace it.

Heater does not blow out any air


There is a fuse panel under the dash on the driver's side and the maxi-fuse box is under the hood on the driver's side. If the fuses are good, it is probably the blower fan which is located under the dash on the passenger's side. (Behind the glove box.)
