Hey guys, i am brand new to forum here, So i don't think i am posting this in right place. But i will give it a go anyways.
I have a 2002 Ford F250 4x4 7.3L super duty XLT. My defrost does not work, i have been doing some research on it, and i see people saying could be the vacuum, could be the flapper door.
Checked vacuum, looks like it works good, i have seen that people are saying, that the default position if vacuum is out is "defrost" position. This not being the case with my truck. I have accessed the flapper door, through behind the glove box as well. seems to go through all functions when u move the switch, but when ever u go to defrost, it blows out the front panel vents, and when u unhook the vacuum thinking it will go to default defrost, it still comes out the front panel vents. all other switch positions work, AC, floor, etc. I then thought maybe its the selector switch, ordered a new one for $30, and crossed my fingers...Got it today, same thing still happens. I have been unable to find any vacuum leaks, when i go to move the flapper by hand, thinking that maybe its just not getting set to the right position, i can not get air to come out of defrost no matter where i manually move the flapper, can get it to come out everywhewre else its supposed to, just NO defrost! . Gets cold where i live, NEED HELP
Thanks!

. I think its possible, the first flapper system i got into behind glove box (right after heater core), was vent control or something. This other system is directly in middle of dash.
