Smoke coming out of vents

Smoke coming out of vents
The A/C is finally fixed, but now smoke is coming out of the vents. It fogs up the windows and comes out at random times. Could it be the heater core and if so, how do I know for sure?

I am illiterate when it comes to auto's. Since finding this site I've been able to do many things myself, but I need instruction. If the heater core goes, will the truck still run? How difficult is it to replace and how much will it cost?

If you can stand being without the heater, yes. Just loop the hoses together where they enter the heater core at the firewall under the hood.
The heater core is pretty involved as far as replacement goes. It is not particularly difficult, but can try your patience and is lengthy.

Well, seeing as the heater core is part of the coolant system, It would still run but you'd have coolant leaking leaking into the cabin of the truck, and depending on how bad of a leak it is, you'll have to top it off regularly, so it's really something that you want to fix. Like it was said above, you'll have to pull the entire dash off the truck to get to the heater core. It's a big job and more than likely a 300 dollar one.
Sometimes, when it's humid out and I put the defrost on I'll get a white mist form on the windshield, is that what you're asking about? I've taken this to be normal, I've had the truck a year and a half of it's 4 year life now. I can tell you the heater core isn't going on my truck.
*edit* Didn't see Kyle's post, sort of repeated one of his points.

It is possible that you have a leak elsewhere in conjunction with the heater core. The smoke coming out of you vents is a dead give away for the heater core, though.
From Oktain:

This is because when you run your defrost, the A/C kicks in. If you don't have the temp selector in the warm/hot area it is just like putting A/C on your windshield. When it is humid out the moisture in the air will condense where the cool air is hitting the windshield. This happens on the outside, not the inside. Happens all the time here in the south.
