2003 Ford Expedition air only comes out of defrost vents on all settings

Asked by Jun 12, 2017 at 03:55 PM about the 2003 Ford Expedition XLT

Question type: General

I am not getting any air coming out of my front
vents. On all settings it only comes out of the
defrost vent. Front vents don't blow any air out. I
checked vacuum hoses and found one unplugged
going to a valve that goes to the canister behind
the battery. Replaced a small curve hose that was
cracked going to another valve near the Egr valve.
Most of the hose were wrapped in that plastic
conduit. Took out tha battery and checked but
didn't see anything out of the ordinary. From
reading alot of post it doesn't seem like it's the
front blend actuator( cause I don't hear any
clicking). I have manual controls and at all settings
it only blows out the defrost vents. I'm so puzzled
now and need help to resolve this. Could it be a
fuse, relay, or could I be overlooking what could be
a hose under the conduit? Any help will be very
much appreciated. Thank you in advance!!!

Sounds like a vacuum leak.
