Very interesting!!! Where do I have to access to see if the blend door is jammed?

 

open hood. go to passenger's side by the cab. you'll see an electric motor bolted to a black box that's attatched to the cab. there's a vaccuum actuator on top. try to move the lever on it. if you can't then take the motor out

 

Sweet! Thanks Erik!!

 

I don't think it would have to do with your t stat, my 95 runs the same around OR and if I turn on the heat it blasts me out of the cab.

 

hello, it does sound like a heater core. any repair shop that works on vehicles newer than 95 should have a scan tool. most will have keys for diesel trucks too. a lot cheaper to go to a smaller shop than a dealership

 

no problem. dont try to get the door out without knowing how. you shouldnt need to but its a pain and i ripped half my hand open when i took my broken one out. i actually have a blower and a door on the bench ready to go in whenever i vacuum the box out

 

LOL I'm nowhere near being blasted out of the cab; I'd sure love it that way though!

Thanks for the advice brother! I think once the weather clears up I'm just gonna flush the cooling system and heater core for the hell of it.


Hmm.. in that case, I'll be swinging by your place of it comes down to that

 

my only thought is how would it be stuck? unless a big object got in there because its not a big pin. its just a little plastic shaft. two things i could think of. vacuum issue to it. or the actuator itself unless somehow the door broke. mine was but the blower was out of it so i'm assuming it was broken then. don't see how it could be broke though.

 

Well thats why you are the expert.. you can assess the situation all you want when I get there buddy

 

yeah that'll take me all of ten minutes
