2001 Ford Taurus 6 cyl Front Wheel Drive Automatic 118k miles
Ok. My car blows hot air for just a minute or so then goes cold on me. If I turn the heater off for a minute then back on. I have hot air again but only for a mintue or so. I have changed the thermostat and with my luck I have cracked the housing. LOL. So I have a new thermostat and housing. I have went in and taken the heater hoses connected them to a water hose and clamped the bypass hose off next to the fire wall and got good clean water flowing through. I did that in reverse as well by changing sides. I have turned the car on and just turned the heater dial from cold to hot on and off to see if the blend door is working. I do hear it running. WHAT IS MY PROBLEM. How do I double check the blend door to see if it is just stuck or stripped or whatever before I spend 8 hours of my day changing a heater core that may not need replaced? Please help me before my wife takes my car and makes me drive hers. Its funny but its that or I fix it. You know the wife will win the battle in the end. So someone please help me. If possible please give detail intsructions or pics. I am not totally a beginner but need help and can follow directions very well if detailed.
Thank you for your time and help.
