#43 of 52 06 Blower Vent Control doesn't work by vicaguilar Apr 27, 2009 (10:08 am)
My '06 Exp. A/C blower ventcontrol (?) just stopped working this morning. A/C will turn turn on and off but air only blows thru top vents. When I turn control knob to other vents nothing changes. Any ideas out there? Any and all help is greatly appreciated. Replies to this message: flyinghigh2 (Apr 27, 2009 10:34 am) vicaguilar (Apr 27, 2009 11:15 am)
#44 of 52 Guess What?????? by flyinghigh2 Apr 27, 2009 (10:23 am)
On my way home this morning, I was turning a corner and hit a small bump and hear a noise under my dash like something rolling or a rattle. I became curious and thought.... Could it be????? I turned my position(air flow) dial from off to panel.... And I had fresh cold outside air flowing in again!!!!I looked at my water temp guage and it was fully warmed up. I guess it was a stuck door as I have heard ohers talk about. Could it be? I won't turn my temp control to heat again, for fear the door will stick again until I have time to fix what ever caused it to stick. Now I can use my air conditioning again when I need, because it won't be fighting with the heater. If anyone has encountered such a thing as I have, please let me know what I need to do to fix this. I wonder if the door gasket is sagging and interfering with the door.Maybe it isn't the gasket because NO heat is seeping through at all. I guess I can't lube anything near the door because it is inside the 'box' ? Thanks for your responces so far. If I need heat, I will use the rear passenger heat...... It works fine( temperature control). Thanks. Scott

Replying to: vicaguilar (Apr 27, 2009 10:08 am) If you have the same system as my 99..... It could be the vacumn diaphram or a cracked or broken hose?? Mine sounds like a vacumn system because when I switch my dash blower locations, I hear a short hiss, followed by the doors 'blend doors' closing/opening. I have known this vacumn device to be located on the passenger side behind the kick plate.as it is on other vehicles. I would assume that to be the location. I really need to buy a Chiltons manual though . Hopefully you have an easy fix. Check the fuses????? Thanks. Scott Replies to this message: vicaguilar (Apr 27, 2009 11:15 am)

Replying to: flyinghigh2 (Apr 27, 2009 10:34 am) I did check fuses first thing, I will try and listen for hissing sounds. Are the wires behind the contol knob actually wires or are they vacuum hoses? When you say kick plate, do mean left or right side of passenger side? Thanks for the advice, Vic.
#47 of 52 Passenger side/right side kick plate by flyinghigh2 Apr 27, 2009 (11:26 am)
Right side of passenger side. And they may be vacumn tubes instead of wires behind that switch. I am not sure. That is just a guess and the tubes can be color coded (AND LOOK LIKE WIRES). so the assembler knows where to attach them to, under the dash. This is just a guess. I am sure that mine is vacumn activated by the sounds I hear when I switch dash vents. Call a Ford dealership and ask if the vents are vacumn operated ....... first, before taking my word for it. It is just a guess and from past experiences with other vehicles.. Thanks and good luck. Scott

#50 of 52 climate control seat problems by sardo May 17, 2009 (9:49 am)
I have a 2004 ford expedition eb 5.4. last night i noticed that the driver side climate control seat was not working even though the thumb wheel light was illuminated. The passenger side was working fine. I tested the switch by putting it in my buddy's expedition and it worked fine, so i'm thinking it's something a little more serious.
