hi i like nomey
Blow by. Compression is passing the rings.
You blow through it
a massive overload of that particular circuit... cheers Aussie charlie..........
There is a dead short to ground in the circuit.
blow back or blow-by is pressure that builds up inside the engine causing oil to be blown out of vent,oil stick,oil filler cap, or into air breather.. Causes of blow-by ---- Bad PVC valve (Positive Crankcase Ventilation ) Worse case is worn piston rings or cylinder walls - engine needs to be rebuilt. http://en.wikipedia.org/wiki/PCV_valve
The air of your Chevy trailblazer 2004 blow out of the front vents when the air conditioner is on because the air condition is faulty and it needs repair.
Coming out of the vents around 43 degrees
Check freon level first
change the thermostat setting
Vents are uaually operated by vacuum. Chances are, you have a vacuum leak at the directional valve or at the back of the air controller itself. All of these are in or under the dash. Good luck.
An air conditioner evaporator is the part of the a/c system that the heat in your car transfers to causing cool air to blow from your vents. The blower is in front of it and it sucks air from the inside of your car and across the evaporator then blows out your vents.
Moisture in the air condensing into mist.
Likely, your blower (fan) is out.
You probably have a jammed or otherwise defective vent door.
I have exactly the same problem on my 2000 Still looking for the answer
The vacuum supply line from the engine is disconnected or broken. When the vacuum supply is cut off the system defaults to the defrost mode.
The HTR RR switch in a Kia Sedona determines which air vents the air is blown through from the rear heating. When it is pushed in, the lower vents blow hot air, and when it is not pushed, the roof vents blow cold air.
