Question about 1999 Ford Taurus

No Heat in 99 Taurus

When winter rolled around this year, i noticed that had little heat. The air would warm up at higher rpms and at lower would blow cold. I flushed the heat core and replace the theromstata nd this seemed to help a little at high rpms, but would still blow cold at idle or lower rpms. After work, I started my ride home and did not have any heat. The tempature gage was a little high them normal, so once the car cooled down, I added some raidator fluid. The temp gage went all the way down to cold and i thought everything was ok. On my morning drive to work i again had no heat, but the temp gage was barely moving. The gage would not rise to the first line when driving and would rise to the line when idleing. Any thoughts?

    if thats the case what is the best way to remove the air lock

    Squeezing the hoses helped with the temp gage showing the car is warming up and i have a little heat now. I still have the problem of no heat at idling.

    I have exactly the same problem that mike053620 has. I can't add anything other than if I turn the fan to blow at higher speed the heat gets colder faster. I haven't changed the thermostat and my temp guage slowly rises to normal and stays there like I should have enough heat to blow me out of the car, but I don't.

    I have a 1999 Ford Taurus also and have a problem with my heating system also. My husband replaced the thermostat, water pump, the heater core and the blend door acator, and we still get cold air. The car heats up at idel, but when I drive the temp gage goes back down to cold and blowes out cold air once again. Whatelse could possible be wrong with this dumba__ car.

Just finished fixing my daughters 1999 taurus heat. It would blow warm only when running down the road. At idle it blew cold. I started with replacing thermostat, and water pump because they are the easier fix. Still did not help. Then I replaced the heater core. A daunting job but not that hard to move the dash slighly out of the way to replace. There is a good write up at tarusclub.com. After that, heat was better but at idle, it would still blow cool sometimes. Researched and found answer. Park car on the steepest hill you can find with front of car up. Start car and take off reservoir cap. Let car warm up and keep rpms about 1500. After a while the fluid will come running out of the car and all over the place but it will bring air bubbles with it. Reduce rpm, add more fluid and repeat about 3 times. It will make a mess but after that, the heater works perfectly. We get heat long before the temp gage indicates any and it never blows cold unless you lower the temp.

Heater doesn't heat when cold


Chances are it is indeed the heater core as even a spent heater unit will blow hot air off the engine when the ambient temps are hot . When the temps drop, the heat from the engine block is not enough to heat the cab properly. Have you tried the old cardboard in front of the radiator trick? Speaking of semi's,ever notice they cover their radiators in the winter? That's because it helps get their block temps up a little higher and assists with heating as well. It's not much help but do the buyer a favour and let them know beforehand. Have a good one. :)

My 2002 taurus only blows hot air when I'm going at highway speeds or close to it(about 2000 rpms) When I drive in town it only bows slightly warm air.


Quite often it ends up being a restriction in heater core, due to calcium etc build up in the heater core, and therefore requires a higher engine RPM to push it through at proper volume to get proper heat. So when idling or lower RPM's, it doesn't circulate it through as well, then once you increase RPM's by stepping on the gas pedal, it increases the flow, and you feel more heat. Here's a link to a tip I put on this site pertaining to that particular problem. It may help you decide what to do about it. Mind you a good flush, and reverse flush at a local rad shop or repair shop may do it, this link will explain what I did that worked, and it's worked many times over the years for me, and is relatively cheap, as long as you have someone a little handy with basic tools around that can do it.

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.

99 Taurus heater not working.


sounds like you may have an air bubble trapped. Try loosening the radiator cap & running the engine at 1500 rpms till the thermstat opens & see if you can "burp" the air out. You may lose a little coolant this way. shut off car & recheck coolant in radiator and reservoir bottle. Just because reservoir is full, doesn't mean radiator is full.

No heat


Some Ford products have a problem with particles cloging up the heater core. I would start with that.
