AC Vents and defrost

[JohnH55]

I've got a 2001 Explorer Sport, over 280,000. I have always had a strange issue with the vents. No matter the setting it's on air will always come out of the defrost and what ever actual setting it's on. For instance MAX AC it will blow half out vents and half out defrost, normal AC is 75% defrost and 25% vent. Even for floor and vent it still hits defrost. I have checked vacuum lines they all look good and I never found a leak. I replaced the vacuum bubble with an OEM Ford part i tested and it holds vacuum at WOT. What in the dash do I need to replace to fix this issue?


Thanks,
John

Did you check the blend Door module?
You did not state, if was manual or auto temp control?

I have not checked that. It has a normal temp nob, blue to red so I'd believe it's manual. How would I check the module?

I could not find a diagram on it.

Good video.. Wonder how often that rear bolt gets put back...

Alright I checked the blend door motor and it was functioning correctly.

It's not the blend door, that does hot to cold.

In the how to section is a thread for this,

How to: - 2nd Gen NO AC ( or heat) FROM VENTS!!! A "How to" what to look for thread

Here is what to look for if you have a 95-01 with cold ac, and hot heat, but it only blows from the defrost vent. IF YOU HAVE COLD AND / OR WARM AIR BLOWING FROM DEFROST DUCT ONLY THIS THREAD IS FOR YOU!!! I will immediately delete all ac cooling questions without answer-let's stay on track...

Thanks Turtle,
I think I'm going to try and use a brake bleed vacuum pump and test around to see if I can force the vent/defrost to move fully to the vent setting.
