my ac still blows an its cold but it will only blow threw the defroster on the windshield does anyone know the problem an its a 07 250 king ranch with the digital ac

Sounds like a vaccuum leak or the electric vaccuum pump isnt working

[kingranch89]

what does that take to fix

[jcs]

If its just a vaccuum leak its a matter of finding it could be under the dash or in the engine compartment the heater vents and auto locking hubs operate on vaccuum

[kingranch89]

i dont have auto locking hubs how much you think this would cost from ford

[jcs]

I couldn't say but its probably about a 100 bucks an hour for labor. I would look around under the dash and what not for a broken or unplugged vaccuum line first it may be something obvious

[kingranch89]

ford said the problem is the vaccum pump is not turning on........do i need a new one? ford did not have time to figure out the problem they cant look at it til monday

I have the exact same symptom. Worked fine this morning and now it only blows out the defrost vents.

I'll start looking for vacuum lines under the dash jcs... but do you know where the vacuum pump is located?

Thanks!

[kingranch89]

it right in front of ur passenger side battery i had to replace mine it was 200 bucks from ford but u can get them off the internet for around 100 they are really easy to replace i almost guarantee your vaccum pump went bad also it is very common in our trucks
