A/C help

[ihot23t]

I need some help with my A/C. When I first turn my 2005 sport trac on the A/C works great. After about 20 minutes of driving the blower motor is still working but there's no air coming out of any of the vents. Well there is very little but it is still cold. I can turn the A/C off for about 15 minutes and start the A/C again and it works for about 20 minutes again. I have looked at the blend door and some of the vacuum hoses but can't pinpoint what seems to be the problem. Please help!!! Thank you!!

You can check the "air recirculation door", which is located behind the glove box. It is housed inside the" upper" black box above the blower fan motor and it only takes removing 4 screws(2 on left, 2 on right) to spilt open the air box and see if the air recirc door is laying on it's side in there. The door should be hanging upright in the box by it's hinge points, not on it's side. When on it's side or broken off, it will block air flow to the dash vents. If you find it on it's side, just pull it out of the air box and the air flow to your dash vents will be restored. Use some wooden wedges or what ever you have around to hold open this air box so you can pull out the door panel. I don't have the web links for this repair handy, since my old PC crashed and I lost those records. Use the search box at the top of the forum and type in "Air recirculation door" and it should pull up the posts you need with the pics on where to find this door and what screws to remove. Look at the post by "Curtis", it has the photos you want. Disregard his instructions on removing the blower motor, no need to remove it to do this. If this isn't your problem, then I would focus on something to do with the dash vent vacuum motor that actuates the dash vents. BTW, the temp blend door or blend door actuator wouldn't cause you to lose air flow to your dash vents, just cause you to lose heat inside the vehicle because they usually fail while set to the cold side of the system. Also, you have a Sport Trac model, so it is possible your air recirc door could be located in another place behind the dash, I don't know. Double check on that.

Thanks for your help. I found the air recirc door behind the gauges. It was not broken. So I'm gonna look for a vacuum leak now.
