Little to no air coming from dash. Why?

[Swamp Fox]

Can anyone point me in the right direction as to why my airflow from the dash is almost nothing? Help!

Does your problem get worse when pulling a hill?

If the blower motor is blowing good air flow on all settings, but you just can't feel it thru the various dash vents, then read the link below for the "Fresh air recirculation door" repair. It is a common problem where the air recirculation door falls of of it's hinge points and lays down flat, on top of the blower housing, blocking the blower air flow to the vents. There are two ways of restoring your blower air flow, re-install the air recirc door back into place as in the link post or just removing the air recirc door from the system as I did. Removing it from the system is the easier and quicker fix to get the blower flow back. You could always go back at a later date and re-install the air recirc door. Hope it helps and post up your findings or repairs so others can use your post in the future. BTW, the 12th, 13th and 14th photo in the link post by "Eyeinthesky" shows where the air recirc door is housed behind the glove box and in the 12th photo, is where you will find the air recirc door laying on it's side and where you can remove it from. To remove it, all you need to do is roll the glove box down and out of the way by pressing in on the 2 side tabs, then remove the front 4 screws to the blower air box, 2 on each side and then split the air box open at the middle seam as in that 12th photo. You don't need to swing out the whole dash as in the actual repair of the air recirc door.

You need to add a little more info about what settings you have the HVAC system on and the conditions it occurs for someone to accurately try and diagnose it.

The blower is working fine and even the vents facing out seem to pass air but the dash defrost vents along the window base and the two facing the side windows have little air passing through. Sorry should have been more specific.

You may still want to split the blower box open at the middle seam by removing the front 4 screws I mentioned earlier, just to rule out the air recirc door having fallen off of it's hinge points and blocking air flow to some vents. Use pic 12 from the previous web page I gave you as a guide to split open the blower air box. This is the pic with the guys hand/fingers right infront the split open air box. Reach inside the opening and feel around for a plastic and foam covered panel approx. 5 in high by 11 in long laying on it's side.
The other thing you may have a problem with is one of the vacuum run, dash vent actuators either broke it's actuator arm or the vacuum line popped off of the nipple to this vent actuator. You'll have to look behind the dash thru the glove box opening while switching the vent control knob and watching for movement in the vent actuators/arms back there. Look for a broken arm or missing vacuum line. Also look for a vacuum port, with 5 or 6 different colored vacuum lines coming off it and follow the lines the best you can to the actuators they control. Check the link below for this type of problem.

I will have to do a little investigative work as you suggested. When we first bought the Ex used the dealership had to do work with blend door. We will see. Thanks for the feedback.
