Question about 2002 Ford Taurus
I finally had my mechanic take everything apart and he found the door that switches from cold to hot in the heater box had broke and cannot be repaired. He told me a new heater box is around $500. I had him push the door to the heat side and stop it from going to cold. Can't afford the fix right now.

Thanks for those suggestions. i did have a total radiator flush and tank replacement done 1 year ago on my 2002 ford taurus. after wards the mechanic let my wife know if i had any problems i might have to do with the heater core. i also dont get much heat. and when i do it usually is because we are at 30-60 miles per hour. it is slow to heat anyways. my thinking was heater core because of the gunk i had before it flushed. i did put radiator cleaner in and ran for a long while. i did a back flush and the water pump squeals but no leaking. i did take hose off of the tank on radiator side and blew into it and the pump quieted down. when presurized the flow from the tank is working fine. i just dont know if it is the heater core or the pump or the valve? as i was reading this article the tests of the hoses were the same. i know it is a long process to replace heater core and that is why i am on here is to get to a site thats free to get instructions on replacing the heater core incase these other techniques dont solve my problem. if any one out there has info where i can go i would be greatful. my wife can be like a heater blowing cold to warm air. not very pretty.not to mention the time to replace the heater. do i have to take something apart to access the vent valve to see if it is working?

After the car is running for 10 minutes open the hood and feel the two hoses going to your heater core in the fire wall dash area. Are they the same temp?
1) Your temp should be set to high with blower on. If they are the same temp the water is flowing through the heater core. If you still do not have heat the problem is the vet door is not switching from AC to heat . This is located under the dash. THe selanoid door may je jammed, a wire may be off or a vacuum line off to that particular vent.
2) If the temp of the two hoses is different temp one decidedly cooler or hotter than the valve that send the hot water t the heater core is mal functioning. If it mechanically opens and closes this can be corrected by manually moving valve to open. Again if electrical or vacum - check for wire off or sticky vale. If the valve is bad replace it yourself with minimal difficulty.

You have a plugged up heater core. Try pulling the heater hoses of where they go into the firewall, put a garden hose with a spray nozzle in one hose and gently flush the system out. you will need to pull both heater hoses off to do this.
