This quite a job. you have to remove the dash. you have to lower the steering column, have to let the freon out of the system. its a 6 to 8 hr job at a shop. if you have no experience i would not mess with it. if water is leaking into you car there ia a way to bypass the heater core, where the two heater hoses come to gether at the engine, you can loop them . otherwise you can get a chiton manual or haynes that might help you replace the core.

1998 Ford taurus doesn't have heat for defrost or interior

If both heater hoses are hot, the problem could be a stuck or faulty blend door under the dash.
The blend doors direct air thru the heater core and out the vents.

On my 1998 ford taurus the heater core is good my fan blows and the ac works but have no heat and i need heat

i used to own one of these vehicles a common problem you will have to replace your heater core most likely it is will not leak but to test put your hand on both heater hoses at the rear of the fire wall if one is warm and the other is cold that is a lack of flow......also a common problem for your vehicle is faulty water pumps the fins on your pump will rust away causing poor flow.......good luck

your description is very vague, if you are not getting enough heat inside the car, you may have a clogged heater core, that is very common on 3.0L ford products,you or your mechanic can remove the hoses from your heater core and flush both ways with a garden hose

Still very low heater output after changing thermostat, water pump. Blend door ok. car does not run hot. takes a long time for temp gauge to read from cold

These Tauruses had a problem with the heater cores plugging up, blowing out the head gaskets and no heat issues. Ford issued a TSB#98B26 (Tech Service Bulletin) to modify water pump and install a heater hose bypass tube. I would start by completely flushing the system with a good flush. Then reverse flushing the heater core. Refill the system and add a good additive. Also you can install the heater bypass tube as described in the TSB. The last one I did ran around $90 and 2 hours labor. Hope this helps you out.......

Bought son 98 Taurus, blasts cold a/c air and defroster air blows, but it won't blow warm air-no heater. can't see out of windshield with the morning sun.Husband flushed antifreeze and changed thermostat....

feel the two hoses going into and out of the heater core. they both should be hot. if one is cold the heater core is likely plugged. you can try flushing it out to see if you can restore flow to the heater core. if they are both hot the thermostat may be sticking open tho you should have a limited amount of heat. also confirm that the vents are operating as they should be.

Heater blows out cold air half the time

Check the coolant level. It might be air buble in a heater core. Also it might be water pump problem.
Good Luck
