Question about 2004 Mazda MPV

Certain smell is coming out from the air vent everytime i open the A/C.

I got a problem with a certain smell coming out from the vent everytime I open my A/C or heater. I am not sure what causing this smell. I tried to swith off the A/C every time I arrive home, and keep the air blower open for few minutes before I switch off the engine to dry the mold, if ever there is, in the cabin air filter. It doesn't work. So I thought I have to have my cabin air filter be changed. Can I change my cabin air filter myself? Is the cabin air filter the same as the engine air filter? I got my engine air filter cahnged a few months ago.

Cabin air filter is inside a compartment behind your glove box. pretty simple to fix if you can figure out how to take off your glove box door. the filter is little different than the air filter, thinner. May help to spray some Frigi-freeze or Fridgi-Fresh stuff on it to help kill bacteria. an auto parts store should have some for the a/c system.

Smell fuel near carburetor in front.

The carb float chamber is vented to atmosphere and under certain conditions there will almost always be a fuel smell near the carb, especially for those with a developed sense of smell. Petrol is a liquid with highly volatile elements and in hot weather or a hot engine those elements will readily evaporate and then the vapours will drift where they will.

Any abnormally strong or stronger than usual fuel smell should be investigated and while most leaks will be easy to find with a cold engine and cold weather it is worth noting a tiny fuel leak can create a strong smell in mild or hot weather or with a hot engine and be virtually impossible to find.
It will probably be necessary to remove the air cleaner to check for carb flooding and it is also worth noting in the case of an engine driven fuel pump there is a possibility of a leak into the engine crankcase.

Noise when I use the heat very little heat coming from the vents

Angnela, please check your furnace filter. This is a very common issue as these filters sometimes get overlooked. If the filter is plugged it decreases the amount of air able to pass through it resulting in poor air circulation. Also make sure your vents are all open. These is a misconception that closing some vents will push more air to other parts of the dwelling. In essence this is true but it does more harm than good since the HVAC Heating duct system has be specifically designed to move a certain amount of air throughout. You can only push so much air through a 6" round pipe. This is critical in air conditioning as the coil may freeze up f there is not enough airflow across the coil. Let me know if this helps. If not we can dig a little deeper into your issue.

Vents on drivers side blow warm air as passenger's vents blow cold air with ac being on.

You have certain blend baffle doors that are not opening.. I think these are vacuum actuated on your car. Probably a issue that will need a service tech.

2003 Chevy Silverado ac bashboard vent not blowing.

There are controls in your car where you can control the flow of air to certain parts of your car. Make sure that you have it turned to where it blows out of all of the vents and then the air should come out of the dashboard. If this continues then there might be a ventilation hose that has been disconnected and is not getting air to that part but the other hoses are still connected.

Why is it that i smell antifreeze coming into the car through the air vents

99% of the time it is a leaking heater core that gives you the antifreeze will coat the inside of the windshield too possibly reducing vision under certain conditions.
Clean it well after changing the heater core.

I have petrol smells coming from my air vents, is this common. Mostly happens when sitting in traffic.

No not common. Check to see if petrol is leaking anywhere. Check good this is unsafe. Sitting in traffic gives the fumes time to rise up. Try closing the vents if possible but certainly check for raw petrol.
