Question about 1999 Ford Expedition

1 Answer

I have a 99 ford expedition with heating problems. It will heat in the middle section for about 15 seconds then you can feel it go to cold air. We have changed the blend door actuator, thermostat, and flushed it 3 times. 2 times with a water hose and 1 time we took it and had it done with acid. Keep in mind while they were flushing it with the acid it was working but about 5 mins after they were done it went back to cold air. Also, in the middle section it will work for about 10-15 seconds and then you can feel the hot air going cold. I turn it off for about 10 mins and turn back on and will be hot air for about 10-15 seconds and u can keep on repeating this process. Please help!!! It’s getting cold out and I have 3 kids!!!!

Check if there is a vacumn powered valve in the heater hoses, if there is the vacumn hose may be faulty [ broken or crimped.] or the valve is faulty. good luck.

What can cause my heat not to get hot in my 2000 ford expedition? the heat does blow but it blows only cold air.


Feel both your heater hose near the firewall. If one is colder than the other your heater core is bad.
If they are both hot its in the cab controls. Lee

Cold air blowing out of vents when the heat is on but the rear heat works fine 99 ford expedition


Could be the diverter valve. It's the one located near the firewall in the engine bay. the valve is in-line on one of the two coolant hoses that run through the firewall. Have a helper rotate the temperature knob back and forth, with the ignition turned on, and you watch to see if the valve is being adjusted. I'm guessing it isn't. Best of luck!

No heat in 1999 Ford Expedition


My expedition was like that. It turned out that the temp knob was cracked and would not turn the switch so i replaced it with the back knob. Just pull it straight out then check for a crack. good luck

2003 Ford Expedition Heater not working


This is all to common an issue in many Fords starting in the mid 90's, reason they went to a electric motor to control the air blend door , this motor moves the door air that diverts heat or cold from the AC, or mixes or blends it,the motor has failed or the door is stuck in the air duct, the bottom line is that to fix either problem the dash must be removed, no a job for the home mech, takes about 10-15 hrs to complete.
