Change your cabin filter! Also check for any leaks at engine burning off on exhaust. When you close your hood there is a rubber seal ( glass side) , make sure that is in place. If engine is dirty try power washing it. A clean engine is easier to pinpoint leaks

There is clear liquid spilling from tank under rear passenger door 2003 Mazda Tribute

If it doesn't smell and it's not oily, it's probably condensation from the AC or defogger.

What is causing water to leak down onto the passenger side floorboard of my 2004 Mazda 6 wagon when I have AC on?

Feel the water and smell it. If it smells sweet and fells oily, is is coolant. If is isn't oily and has no real smell, it is water. There is a tray under the evaporator and heater cores that catches water/coolant and drains it via a tube thru the firewall to the outside of the car. This tube is probably clogged and needs purged. If you have coolant on the floor, you'll need to replace the heater core. If it is water, purging the hose will solve the problem as the water is just condensation from the AC coils

Air conditioning not working - light is flashing and it blows lukewarm air

Chances are you have a leak in the ac system. Look at the 1/2 inch steel lines under the hood. You will see a dark oily and usually dusty spot where these pipes make connections or bends. This is a good indicator of where your leak is at. If you can't see any obvious leaks. Make sure you have pressure in the system. You can do this by connection a set of pressure gauges. Autzone will let you use for a deposit. If you have pressure and no leaks look to your compressor. Hope this helps.

Smell comes thru air vent.

You might have both. The fresh air intake is under the windshield wipers, that vent takes in the fresh air from outside. The filter is usually in the rear seat section on vans and suvs, somewhere, sometimes up front under the dash. You can switch your ac or fresh air control to recirculate and it will cut off the outside air. We always do it on dusty roads and dead skunks. Hope this helps.

Whenever I turn on my ac in the car I get a misty oily smell through my airco vents so I decided to turn the climate control switch to red for a few seconds to see what that did after I switched it back to...

When you run your AC, turn if off before you end your trip. You're having it on which builds up mildew. Then when you leave your car there, it stays in the vents. When you turn the car back on, that's the smell you get. Not to mention you should not ever turn your car on with the AC enabled. That's going to cause strain on the initial start of your vehicle that could lead to later complications.

Leaks inside from ac

Smell the liquid. If it smells like nothing, it's just water and is only condensation from a very cold exchange unit (like a radiator in reverse). It's just like the water condensing on a cold cup of water. HOWEVER, if it is oily and has an odor, then it is a refrigerant leak and needs to be addressed by a mechanic IMMEDIATELY.

Hope it's the good answer,

coolant isnt oily.
sometimes white vapour (condensation) may visualy appear when first turning on the air conditioner, and that's normal.
oily residue isnt. no idea what it could be.
