Passenger side vents will only blow cold air, but I noticed a hose fitting on the passenger side of the firewall that is missing, and im not able to find where it would go from the firewall, is this my problem, and if so where does the hose go from the firewall.

Are you referring to a 4" long rubber hose with a 90 degree bend? That is the drain tube for the AC evaporator.

No, its a hose fitting directly on the firewall, on the passenger side, there is no hose on it, possibly be the reason that side only blows cold air. And from the firewall where does the hose go?

There's only three hoses, two for the heater and one for the AC drain. If either of the first two were disconnected, there would be coolant leaking onto the ground and the engine would overheat very quickly.

The third hose is a plastic spout that sticks out about an inch or less. A 4" rubber hose that angles down is attached to it with a spring-metal clip. That is the drain for condensation that occurs when running the air conditioning system. If that hose hasn't fallen off, you will see it hanging down and the end will look like it's squeezed shut. It's common for debris to get inside and block that tube. The result is water sloshing onto the passenger side front floor after running the air conditioning for a while. Most of the time that debris can be dislodged by squeezing the end of the tube to open it up. Sometimes the tube has to be removed, then you can stick a pencil into the spout to dislodge the debris.

That tube is not the reason you're getting cold air from the vents. I suppose a cold breeze could come in through that tube but that would blow out the bottom of the dash someplace, not the vents. If there is no 4" hose on that plastic spout, it either fell off or someone removed it to clean it and forgot to replace it. You can find a bunch of them in the salvage yards. They will be the same between many different car models.

If there is something else you're referring to that doesn't sound like what I described, try to post a photo of it if possible.
