When I turn on the heat in my car its barely warm almost cool, what could be the problem? Its a 96 Ford Taurus

Question

I have replaced the thermostat and that did not fix the problem,what else might I try?

Answer 1

Check to see that the heater control valve is working.

Answer 2

One problem has been the blend door or blend door motor.. this is what moves to give you heat or cool.. common problem here in the south

I see more heater cores go bad than plug up but that can happen too and usually it's a replacement than a flush to really fix them.

Also did you bleed the system after you changed the coolant? HUh you say?

The system has to be bleed or will cause same issues.. mainly runnign vehicle with heater control all the way in the red, fan on full blast and in vent position and let engine get warm or go on a road trip for about 10 miles... heat will come gradually but within a minute or so of it gradually heating up it will become fully hot ...

Hope this all helps

easiast thing to do is check the radiator level, is it full? You should have a coolant overflow bottle with markings where the fluid should be at hold and cold. If it is low, this would cause the warm air effect. But next find out why you are low on coolant, check for leaks at the hoses and connections, look for any stains on the radiator and look for puddles of green fluid on the ground. If you are not low of coolant, then you may have a clogged heater core, a malfunctioning heater control valve or a water pump beginning to go bad. usually when the cooler weather arrives the water pump bearing seal begins to seep, so look under the area by the water pump.
good luck

The heater core is a very comon problem on the Taurus... under the hood at the firewall you will find two coolant hoses attached to your heater core spouts.... carefully remove both hoses and flush the heater core thoroughly for 15 minutes... reconnect hoses and top off coolant in resevoir...let the car run for ten minutes with the heater on high and you should have upwards of
130 degrees at your dash vents....use your moms turkey thermometer

Answer 5

It is likely the replacement thermostat is faulty. Try another brand of thermostat or a genuine Ford replacement.

Answer 6

Check to make sure your heating system is completely full of anti-freeze mixture. A low fluid level in the radiator may not allow a sufficient flow of warm water through your heater core.

Answer 7

you need a new thermostat or a heater core. the thermostat is easy to change and inexpensive try this first. make sure your radiator is full of coolant if it is real low you wont get any heat .

Answer 8

attempt a reflush and this time use PRESTONE anti-freez and fill with DISTILLED water you would be struggling with a bad water source with iron deposits in it , no longer undesirable for human beings yet makes coolant water turn brown quicker. p.s. there's a attempt to work out in case your head gasket is leaking, Any solid shop could have the attempt.

Answer 9

Answer 10

Check the heating coil.
