There is smoking coming out of my dashboard when I start driving. what wrong?

Smoke is never a good thing. If the smoke smells like burning plastic, you probably have an electrical problem somewhere under there and should stop using the vehicle immediately and get it to an auto electric shop for repairs. Waiting could cause failure, or worse, fire. If the smell is exhaust-like, then you may have an exhaust leak under the hood and it is coming in thru the ventilation system. This should be checked out quickly, since carbon monoxide, present in engine exhaust, is a toxic poison that can kill if the concentration gets too high. If you must use the vehicle with exhaust gases entering the passenger compartment (and it is never recommended!), ensure all the windows are open to get plenty of fresh air, regardless of the weather conditions outside -- cold and wet is better than warm, dry, and DEAD!

Water evaporation always refilling radiator also when air condition off a vapor comes through the vents

The coolant is not evaporating ,it is leaking from the heater core. The vapor out of your vents is coolant. You probley also have a residue on the inside of your windshield

Vapor emitting from vents of 2005 toyota camry SE

Sounds like you may have condensation in the vent channels. However, not sure how much of an issue it is.

If it were a heater core, you'd notice the coolant smell and fogging up of the windows ONLY when your heat is turned on, not cold air, because when you turn up the temperature, a door adjusts to direct air through the heater core and if it's leaking there, that's when the vapor comes.

So, with it being cold and having vapor, my question is now this: is it constant? Did you have it on heat and then switch it to cold? A temporary burst of vapor shouldn't be anything to worry about. Something more constant sounds like something that should be diagnosed by a tech.

The ac on my 1998 ford ranger only blows out the defrost vent and floor vent. How do I fix it?

Almost sounds like the actuators are inop. depending on which style you have, some are electrical motors and some are vacuum. These control the mode doors which move to deflect air to various vents.

Well, this definitely sounds like you have a blown head gasket, and maybe a busted heater core (water vapor out of air vents). Both were probably caused by the car overheating creating a lot of pressure in the cooling system and blowing the head gasket(s) and maybe the heater core. The vapor out of the vents could also be caused by external coolant leakage of the head gasket on the hot engine bringing the vapor inside the cab via the heater fan...

I'd get that checked before any major engine damage happens...

Front air blows hot air while back air is cold. Can turn it off and on and it will work for a while.

I have the same problem, when running the air conditioning the front vents will blow hot air. I have not removed the dashboard yet, but I think that the air damper is stuck in the open position. It seemed like a heater core valve problem, but I am pretty sure it is a damper under the dashboard. Now however, I am finally getting some cool air out of the airconditioning vents, but when winter comes, I am afraid I will struggle getting heat again.

Smoke/Vapor coming from Air Vents

The whole dashboard of the vehicle will need to be disassembled, removal of stereo, temp controls, air vents, the dashboard will need to actually be pulled away from the front of the cabin, It is a very labor intensive repair.

Turned air condition on, went to turn it off (button out) light is still on and color of light is green when on or off 2009 kia rio.

I may be able to help but, I need some more information. When you turned on your A/C what was the vent selector set at (Floor, Face, Defroster)?

Most newer cars with A/C systems have a built in setting when you set your vent selector to Defrost mode (blowing on the windshield) that automatically turns on the A/C unit. This is normal due to the fact that a fogged up windshield is from water vapor and the A/C does an awesome job of drying the air so it can more effectively and quickly remove that annoying water vapor from your windshield so you can see better while driving.

Try changing the vent selector to full face vent (the vents from the dashboard that you can adjust) and switch on/off the A/C and see if that solves your problem.
