Smoke coming up through defrost vents??

Smoke coming up through defrost vents??
I have never come across this problem in any of my previous vehicles. I you try to run the heater, it pours massive smoke through the defrost vents. If you DONT use the heater smoke still comes through intermittently. Has anyone ran into this before? Is this a heater core? The heater blower motor has been making bad noises for awhile now. Any help would be greatly appretiated, thanks.

Thats what I was figuring, I just cant figure out what else it could possibly be. Atleast they are cheap...are they a pain to replace on these trucks? I have never had to do one...yet. Does anyone know how you tell if you have a "high output heater"? My dash says I do but I know that doesnt mean squat considering that could have come from anywhere.

Is there any smell?? coolant, electrical, and you mentioned you blower has been sounding funny, might want to consider replacing it while you are in the area.

I had planned on pulling it all apart. The noise that I am hearing could easily be the blower wheel (something in it maybe). The smoke (as I called it) is actually steam...it fogged my windshield up in seconds. Autozone has different part numbers on their heater cores depending on if I have a high output heater or not and I don't know how I can tell that. I have also noticed that I have to keep adding water to my radiator, so it makes sense to me that the core is leaking. But I haven't noticed antifreeze smell in the cab. But if I have it all torn apart I will just replace the core no matter what, its cheap enough.

i had kind of the same thing happen to my 98. what mine was is one of the hoses on the heater core started leaking and blowing antifreeze up on the windshield. it sounds like yours is different as you said smoke but i figured i would offer my experience. it is easy to determine if it is antifreeze.

That, or the blower motor resistor is opening up. You should open up the plenum and investigate.
For future reference, you'll get better help if you start a new thread when asking a question. I fear that a lot of folks will see this thread and respond to the person who started it over 3 years ago whose problem may not be the same as yours.
