Your air conditioning cool air is routed to the various vents by routing doors. A malfunctioning routing door can be stuck and remain closed.
Coming out of the vents around 43 degrees
you need to replace your heater core that smoke and oily film is anti-freeze
sounds like your air conditioner compressor is bad.
If dust is coming from your air conditioner, you did not put in a filter. You will ruin your air conditioner running it without a filter. Also, the vents will get dusty. You need to clean them.
this kind of thing happens in my durango when i have the ac on and its humid inside the car.
If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
Steam may be coming out the air conditioning unit if the engine is overheating. The best thing to do would be to shut the vents before any hazardous fumes begin to come out.
Air conditioner drain line stopped up or windshield seal leak that covers 99% of the reasons
I assume you mean smoke and water are coming from the A/C vents. I suspect you are seeing steam and coolant. You probably have a heater core leaking.I assume you mean smoke and water are coming from the A/C vents. I suspect you are seeing steam and coolant. You probably have a heater core leaking.
My 1998 Civic EX engine (CA emissions) vents the upper valve cover into the air intake for combustion. I could not locate a traditional Positive Crankcase Ventilation (PVC) valve on my vehicle.
It's probably mold. You can buy chemicals that are added through the intake that might fix it.
Depending on the year, make, model along with if it has single or dual a/c systems and what the outside temperature is, it can be between 36 to 48 degrees...... Simply, the A/C vents temperature should be whatever you set the thermostat as.
