well my truck has a blown heater core, and i know the blend door is brooken too.. its stuck in the mddle position (not defrost or feet).. But now my question is if i put in the new heater core this weekend will i get heat out those middle vents? Basically what i mean is does the blend doors affect the heat at all or does it just control where it comes out? I dont have enough money to do both right now, so im picking the heater core over the doors cause its getting cold now.. i was gonna look at the doors when i pull the dash (its know its dumb having to pull the dash twice) and see if there is pplastics caught in the motot or whatever.. I hope you guys understand what im asking, thank you.

 

anybody?

 

blender doors do control hot/cold as well as where the air comes out I believe

 

Exactly. So if you dont fix the doors also, you will still get only air out of the middle. So fix all of it or none of it.

 

well one day when i turned on my heat, smoke/steam was coming out the vents. so i went to switch it to defrost, and it doesnt move off the middle vent. i rerouted the hoses to the core, and steam/smoke stopped. so i would assume that its both a blend door and a core? or am i way off and just have to do the doors?

 

The core has only two hoses so no matter which way you route them, it goes in one and out the other. Just focus on fixing the blend doors and while it is all apart, check to see if you get heat then

 

no, not rerouted like switched the hoses, but i took them and connecting them with a 45.. now what do you think weed?

 

damn, what happened to this place... anyone help?

 

You are asking a very specific mechanical question....not usually a ton of help for these type questions...nothing is wrong with "this place"

Also, you're thread title is random and nondescriptive...people with knowledge on the subject might skip over it

What is the question are you asking? The blend doors direct air flow from defrost to panel to floor. The recir door gives you hot or cold. If the heater core is leaking, then pull the dash and replace the heater core and all the doors in the heater box. Just so you know, don't start your post with i have a question. If you have tech question, just say so. In other words, to get the right answer you need to ask the right questions.
