There are several things that may cause those issues - and they are all potentially dangerous ( and labor intensive )!!There could be a bad ground point, burnt or pinched wire, bad relay, poor /corroded connection to the computer, etc. I'm sorry, but this is something that requires a hands on by a knowledgeable technician!
Sorry for the bad news, and thanks for using Fixya!!

SOURCE: gasoline smell from time to time

it can be that one of the injector is leaking and the fuel gets burned on the manifolds thus runningt into the vents, secondly the pressure regulator could be leaking causing the fuel to leak and then again they get burned on the manifold due to tremondous heat

SOURCE: 2001 pontiac montana heater is now blowing cold

You need to check coolant level in rad, when cooled down, and top up your return bottle to marked level.
Start by having coolant (antifreeze) ready, remove your rad cap, and top up the rad level, then start the vehicle, and turn on your heater (not defrost) . Let it run with cap off for a while, and keep an eye on level of the rad & top up as necessary, but leave an inch or so from top.Let it run & observe your guage while doing so, and when gauge gets to normal operating temperature, your rad fan should come on, run for a while then shut off for a while, then back on again after little while, and off again. Let it do this about 3 times, top off the rad as described above, put cap back on tight, and top up your coolant return bottle to mark on side. If your rad fan doesn't come on around normal operating temperature, and gauge heads too much towards hot reading, shut vehicle off, that's an indication that your rad fan fuse has blown, or relay, or fan itself is defective. If all works well & you now have heat, great, but keep an eye on your coolant return bottle level for next while to see if it keeps going down, and add as needed if it is. If the level in bottle continues to go down, you've got a leak in the system somewhere & need to address it a.s.a. p. to hopefully avoid bigger problems, but we'll get to that only if we need to. Do what's up above and let us know the results.

SOURCE: engine smokes and burns of oil or something else burning.

both of the other answers are possibilities, just check both fluid levels. if tranny oil is low but you see no smoke at all under the hood while it is running and you are looking at the motor, it could also be that you have some piston rings not sealing. it will usually result in low oil pressure also.

White smoke from air vents while ac was on,greasy film on window while defrost is on/heater coil?


Yes. The heater core is leaking bad. The white smoke is the coolant and steam. Be sure to add water to the radiator before you burn up the engine.

Heater of car smells


A mouse or leaves from a nearby tree have gotten into the AC/Heater blower motor and they are touching the blower motor speed control resistor, this is very hot and makes them smolder and smoke and smell. You will need to remove the blower motor from the housing that it is in and clean out what ever is in there.

Fogging up issues


If you can feel the air from the blower motor blowing up on the windshield it is probably one of two things. Either your heater core has a leak and the anti-freeze mist film is all over the windows or your heater control valve is not working.
Does the heater get hot or can you feel hot air on the windshield? If so your heater core is probably leaking and making steam inside your car.

Heater core or blower motor?


Sounds like your blower motor , you heater core is a non mechanical part and if it were the issue you are correct in thinking you would see fluid on the floor or mist on the windshield.

Burt Toast Smell while running heater


This is caused by in most cases dry tree leaf getting particles into the heating duct through the air intake at the base of the windshield, this material contacts the red hot blower motor speed control resistor and burns, and yes it smells like burnt toast, in order to clean this stuff out u need to remove the blower motor, the material will be in the duct near it. I have seen this cause a fire, so get it checked and cleaned ASAP.
