#1 of 81 dash vents by doozer22 Jul 22, 2006 (12:07 pm)
I've been searching / surfing for the heater dash vent that is between the steering column and the glove compartment. It is broken on my 1995 Merc Sable. NO LUCK !!!!!!! Any suggestions. I've tried the local junk yards and the dealer isn't interested (I guess they cant make lots of cash)

#4 of 81 Ford Taurus Heater problem by knowhoweman Jan 25, 2007 (7:26 am)
We have a 2000 Ford Taurus SE that I have a hard time figuring this thing out. The temperature gauge shows good, right where it's supposed to be but the heater puts out less than luke warm air. I have changed the thermostat. Could this be caused by a clogged heater core? Can I backflush it? If I have to replace it, how do I do that? Fluid levels are good.

Replying to: knowhoweman (Jan 25, 2007 7:26 am) I have not tried this yet, but will on Sunday. I have the same problem with my 99. It seems to be very common. A thread I read said to remove the heater hose from the pump pour in liquid plumber. Pinch off the by pass on the fire wall. Remove the return (out) from the heater coil at the return by the thermostate. Then flush the coil with water from a garden hose. Many people said that solved the problem.   1. pinch off the by pass hose ( you will see this run above the heater coil in/out lets on the fire wall. 2. Remove hose at the water pump going to the fire wall. 3. Remove the return hose from the coil to the block 4. Pour liquid draino into the hose going from the pump to the coil 5. After 10 min, flush with high pressure water. you can also back flush because you have both hoses off.   good luck

Replying to: knowhoweman (Jan 25, 2007 7:26 am) Could this be caused by a clogged heater core? Can I backflush it? If I have to replace it, how do I do that? Fluid levels are good.   It is very common on the taurus to have a clogged heater core. You can check this by removing the lines coming in and out of the heater core. Remember to block the bypass line around the heater core so you can push all the water threw the heater core. You can then put a garden hose on the heater core and see how much flow you can get threw it. Don't add too much pressure of you may damage the heater core and cause a leak. If you are getting good flow it is not the heater core. If it is totally plugged then the draino trick will not work either. (Be very careful if you do choose to go the draino route) As for having to replace the heater core, it is a real pain in the you know what. Unless you are good with wrenches and have a high tolerance for frustration it is a job best left to the professionals.   Now if you have good flow threw your heater core then it is probably a blend door actuator. The blend door actuator controls the amount of heat that you get with your heater. On the taurus it tends to fail quite a lot. The little plastic gears go bad and the heater will not work as if fails in the cold position. I think they are around $70 at ford and fairly easy to replace yourself. It is located under the center consul. You can test to see if it is working by turning the fan on high and turning the hot-cold switch. You should be able to hear a different noise as the air flow changes. You should also be able to hear the blend door come open and closed.   Good luck.

I need help! I have a 97 taurus wagon with a 3.0 l engine. The temperature gauge reads normal but when I make sharp turns the gaugs goes to cold. This also happens at highway speeds. When the gauge goes to cold there is no heat in the car. The heater core has been flushed, the thermostat has been changed. 13 months ago I had the head gaskets replaced. There is also coolant leaking from the radiator cap, sometimes. I replaced the cap. I am concern that there is pressure building up.

Replying to: cimino (Jan 28, 2007 12:31 pm) Not really sure what the problem is, but are you sure it is leaking out the cap? The coolant tank on the 97 Taurus is notorious for getting a crack in it and when the pressure builds up it will leak. It can be very hard to find because it often will not leak until there is pressure in the system. I have a 97 Taurus that I use for a work car and I thought I had a head gasket problem too but I found a crack in the coolant tank. I found my leak on the bottom of the coolant tank but it did appear sometimes it was coming out of the top. It would leak the most when I would turn the car off after driving it hard.     I don't know why you are getting a cold temperature but the coolant tank has two chambers. It will actually work will very little coolant in the system. If the coolant gets too low the gauge will bounce around quite a lot.   Good luck. The good thing is if it is a coolant tank then it is a very easy fix. I think the tank is about $50 from ford and much less from Auto Zone.

Replying to: shasta67 (Jan 28, 2007 4:14 pm) Thanks for the info! I forgot to list this the first time. When I make a hard right or left turn the temperature guage moves from normal to cold and results in a lost of heat. Also driving on a highway, the temp. gauge will go to cold with not heat and then for no reason the temp gauge goes back to normal and the heat is also back. Any ideas?
