Heater problems

[Jakers_AK]

Looked and couldn't find any threads with this particular issue. My heat gets hit, the issue is that it blows out of all vents. The floor, dash, defrost all at the same time. Is this a problem with the blend door actuator or something else? And if so, where might it be located? I have a parts truck so if I have to tear into that one for practice I will but it would be nice to know exactly where I should be looking. Thanks.

Oh yeah, it's a 2004 Adrenalin and my parts truck is an 02 model if that makes a difference in where the thing is located or if it's the same part.

Have any vacuum leaks? Check engine light on?

AC Blows out all vents regardless of setting

Last summer, I turned on the AC, flipped it from 'feet' to 'face' and as I did I heard a loud 'clunk' from behind the dash/console. I expected to hear the fan make noise as it ran, but it didn't... instead, I felt air blowing out all vents (defroster, feet, and face). I checked and no matter...

It’s probably that. Found with one search, was the second result.

Thanks for the response.
it seems that I can set it to blow to the floor and the dash vents but when I put it on defrost it barely blows out of the defroster but still blows out of all the other vents. Check engine light is on but that's another issue. No vacuum leaks as far as I can tell. I found another thread for a regular explorer that had the same issue here:

Defroster Door shaft broken, Need help getting to Pleunm Chamber

Help! I have always had poor airflow from my defrost vents. There isn't enough airflow to the windshield to keep from fogging up with more than me in the car! Long story short, I found that the defroster door on the left side of the plenum chamber is broken(so half of the airflow goes to the...

Apparently there's an issue with the defrost flaps staying shut which would be an issue with the actuator or motor whatever it's called. Something mechanical and not a vacuum issue.

So my next question would be how similar are regular explorers set up to the sport Trac? Are they identical because I really don't want to have to take the whole dash out to fix this but I will if I have to...
