Just recently (last 2 days) the wife was complaining there was no heat in the car, that it was blowing cold air. This afternoon I tried switching it from heat (temp dial all the way to the red) to air conditioning and there was no difference in the air temp. HELP!

We have a 99 Taurus and we've had the same problem. With ours, it was the heater core. We tried to have it fixed once when we had an extended warranty but it wasn't done properly, so we'll have to do it again ourselves. I'm hoping we won't have to replace it all over again.

It's an affordable part, but the problem is that the labor may be expensive if you can't do it yourself.

I also had this problem and it turned out to be a stuck arm on the temp control unit which is under the dash near the floor. there are 3 bolts on a semi-triangular cover which is about 3" long on each side. Take the cover off to access the arm. Then just give it a gentle push up and down and it should start to move. Since it could be stuck either open or closed you should have the temp set in the middle until it moves. I then gave it a quick shot of wd40 to lube it and replaced the cover.

We had the same problem as the above we change everything. Then we check the water pumb that was the problem. Now we have heat. The car never showed any signs that was the problem.

This is caused by a small chip screwed in to the bottom of the blower motor that goes bad
... about 20 bucks for the part.. takes about 2 min to replace

The people who say their heat only worked on high and no other setting, I can almost gaurentee it is your mixing door behind the dash. Its basically a flap that moves to mix cold and warm air to give you temperature control. Hard to get at and an expensive fix. If your broke and in the middle of winter pull out the glove box and look for it behind your dash and just prop it open on the heat side with a pencil or something similar till you can get a chance to have someone look at it.

Flushed Core only.Brown at first then flowed freely and clean Then drained radiator of old antifreeze, refiled w/ water, ran for 10 mins and re-drained. Dirty brown again but then flowed clear. Filled radiator with flush treatment and water and drove car highway and local for about 6 hours over a few days. Engine temp stayed in good zone whole time. Drained, refilled with 50/50 antifreeze/water mix, But still no freakin' heat. What next? Are there 2 separate thermostats, 1 for engine, 1 regulating flow through core?(I've not changed any thermostat yet.) Also I see that the hose from RADIATOR on its way to the core forks off at one point into 2 separate directions. 1 goes directly to the core the other seems to go back into the engine. What's that all about? Is this a safety setup of some kind? Thanks All. Car runs at normal temp. All liquids captured.

We have a 1996 bmw 328I and the heat just stopped working we think it is the draft free ventilation switch how do you take off the dash plate to get to it

I have a 2002 Grand Marquis LSE. I live in hot Houston weather so my A/C is mostly always on COLD. The other day on our first cold day I turned the unit to HOT. Once the car was warm enough for me, I turned the unit down more towards COLD. IT WILL NOT GO DOWN. It is stuck blowing HOT air only. The unit will change fine from say MAX AC to NORM AC fine, and to DEF or FLOOR. It is blowing ONLY hot air on any setting including VENT. Any ideas?

getting very poor heat, so replaced thermostat, didn't work so replaced again, still no decent heat, but when you are parked and rev the motor hear comes through, this makes absolutely no sense, any ideas. this is a 2002 taurus also.

That is a safety bypass. Ford installed it in case the heater core got blocked. that way the coolant can still flow. My 2000 taurus se has the same no heat issue. it's been diagnosed as a bad heater core. since the car has the bypass on it, something tells me ford knew about the problem and didn't bother doing anything about it.

2002 Ford Taurus. heat doesn't work. blower doesn't work. Replace blower resistor 3 times. It's a joke. Ford should fix those cars.

There is a heater blend motor that is directly behind the dash panel, center, bottom, by the floor. It has four 5/16" screws, and a 6-pin wire connection in the center. It takes about 5 minutes to change it out and the part is $42, give or take a few dollars for taxes. As far as blower issues, Ford has had many problems with their HVAC blower burning out. I would look into aftermarket products since Motorcraft parts are not improving thier "issues"
