Heater blowing warm air

[kerstingm]

I hope that I am posting this in the right section, but I have a good feeling that my problem is with my blending door and I was wondering if there was a way that I can get to the door and maybe either have something hold it closed ( or open) depending where it needs to be to get the hot air inside.
Please if anybody has any suggestions please let me know.
Thanks and Marrey Christmas to everybody here.

funny you should ask... i have done this.. yes tons of money on mods and I cheap out on blend door repairs.... google- heatertreater blend door repair and watch the video... basically you remove the glove box and cut out the cover behind it the cut a hole into the phleum (sp) box and then cut a piece of wood to fit and prop the door the right way... mine broke last summer and didnt have cash to fix the blend door, so ordering the heatertreater door (its a 2 piece door) and can replace the door without having to remove the entire dash

make sure its a blend door issue first
are both hoses hot going in the core and out if not its blocked
is the truck getting to temp? if not the stat is bad.
do some investagating first
