Cold air like, really cold or just cool. Sounds like your hot/cold blend door motor has perhaps failed with the blend door in the semi hot position. Blend door motor failure is very common on the Ford truck HVAC systems. Is is located behind the glovebox on top of the HVAC housing assembly.
Ok.I bought a new one from napa....after a month...it did the same thing again.could it be anything else...or maybe I bought a faulty part.thanks
On max ac the air gets really cold.but as soon as I put it on vent with thermostat still on cold..it blows hot
So you have already replaced the blend door motor and it then worked ok for a month and then the same thing has happened again? Is that what I am reading here? If that is the case then it sounds like you may have purchased a faulty part that has failed again. Don't forget that the rest of your heater control system is run with vacuum controled actuators. If there is a problem with the vacuum supply or a leak in the system then all kinds of weird things will happen as you are turning the knobs to change air flow direction etc. the hot/cold control is the only part that is controled with an electrica actuator.
O ok.yea I was thinkin it was a faulty part.I checked all vacuum lines..I ll go buy another part.I guess it would be better to get a motorcraft part instead of a napa part.
