Compressed air noise followed by smoke.

After jump starting the car the engine started making intermittent hissing noises, they sounded like blowing compressed air, from under the passenger side of the engine. A fine smoke came up followed by a burning sell. Smelt like burnt rubber/plastic. The check engine light never came on before or after. What does it sound like is going on with my car?

The stink of sulfur is a sign that your battery acid is leaking. Leaking battery acid is one of the top signs a car battery is dying. A dying lead battery will produce hydrogen sulfide gas, which smells like something between rotten eggs, a sewer or well water.
A blown fuse or a failure with your car`s alternator may be causing it to smoke. Your alternator is under your hood, and any smoking or unfinished combustion should be looked at immediately. The smoke itself is a result of friction and not an impending explosion; this can mean that the alternator is on its last leg.
When an alternator fails, the bearings inside usually have failed to a point that causes them to whine severely and, depending on how badly they have failed, they may also smoke due to the excessive friction they create.
The alternator works with a variety of belts inside your engine, and if a belt is not turning the way it should, the friction will cause a burning smell. If you catch a smell similar to an electrical fire, you might need to replace or tighten a belt.
The bearing within the alternator can smoke due to excess friction when the alternator is dying. You`ll need to get it replaced. Alternatively, the smoke may be due to a blown fuse on the alternator. This is good news, because the alternator is likely still usable.
Unplug it from the power outlet if it is on charge. Avoid inhaling any smoke or fumes. If possible, remove it to an outside area away from any combustible material and away from windows or doorways. Small devices can be dropped into a bucket of clean water to cool if this can be done safely.
Dim Lights. An early warning sign that your alternator is going bad could be dim, flickering lights. This symptom could show up on any or all of your dashboard lights, reading lights, headlights or other lights. The alternator is supposed to provide the electricity for your car`s lights.
A faulty alternator could ruin a perfectly healthy battery, which would put you further back from a solution than where you started. Don`t fret as diagnosing your vehicle`s electrical problem is so easy that anyone can do it by running these tests.
Engine damage is one of the worst-case scenarios of alternator trouble and it is definitely a possibility, but it`s so difficult and inconvenient to keep a car going with a bad alternator that you`ll probably get it fixed long before it causes damage to your engine.
Smells and Sounds

You can also rely on your senses of smell and hearing to identify alternator defects. Many drivers report burning rubber or chemical smells when the alternator starts to fail, and these smells may be caused by burning wires or overheating alternator belts.

If the parts in the alternator are misfunctioning, you may hear grinding or growling sounds. The Smell of Burning Rubber. In severe cases, a faulty alternator can produce a distinct burning smell. If you smell burning rubber, stop driving your vehicle immediately and get help.
A burning electrical smell

Cars are designed with a variety of electrical elements, including the battery and alternator. If your car smells like burning electrical or car smells like it`s burning under the hood, this could be the cause.

Short answer: yes. At low levels of concentration, Hydrogen Sulfide smells like rotten eggs. At extremely high levels of concentration, Hydrogen Sulfide can result in unconsciousness or even death. Even at low levels of concentration, Hydrogen Sulfide can irritate the eyes, nose, throat, and respiratory system.

Hot air mixed with cold blows from air conditioning
ANSWER : Hey there. You will most likely have to have a mechanic bypass the heater coolant lines to have this resolved. Your A/C may not be controlling the air flow inside the evaporator correctly out of the vents and may be the blend door actuator stuck in the heat position. Have the AC system diagnosed first before bypassing the heater.

Cleaning the cabin air filter with compressed air
ANSWER : Sure, not a bad idea–spray it with compressed air. Realize that if you’ve got one of those ones that’s darker black, that’s a charcoal. You can blow the dust out but eventually the charcoal breaks down and it doesn’t filter odors anymore. So, if you’ve got a dark one, it’s a charcoal filter. In this case just go buy another one as the charcoal is going to wear down after a certain period. You can certainly blow it with compressed air, just do it backward. If the air comes from above, you’ll want to blow the other way with compressed air and blow the dirt out so that you do not blow it back in.

Cold mist/smoke like air comes out of the air vents when cold air is on.
ANSWER : If you are using regular outside air a/c instead of recirculated air you may be getting a large amount of outside air humidity and can cause a mist to come out of the a/c vents. You should make sure the a/c evaporator drain is cleared and drains freely or the water in the a/c cannot drain fast enough and the blower will pick up the water and blow it out the vents.

Air conditioning is blowing hot air – car stalls when A/C is on
ANSWER : In order to diagnose all the different problems you have, I having the A/C pressures checked to see if the system is low on refrigerant from a leaking compressor or another component. The rough idle may be due to a dirty throttle body and idle control system. If you would like to have this checked for you, a certified professional from YourMechanic can come to your car’s location to inspect the A/C and rough idle in order to proceed with the proper repairs.

Noise like a siren and turbo completely gone
ANSWER : The most likely cause of these symptoms of this are a failing turbo, large vacuum leak, or a damaged intake. This level of symptom damage to the engine can result from continued driving. If the turbo has failed, it can break and be sucked into the engine causing engine failure. This fault should be diagnosed as soon as possible. A qualified technician, such as one from YourMechanic, will be able to inspect the whining noise, diagnose the car’s loss of power, and perform any repairs required.

Air conditioner blowing warm air. Heat blowing warm air. Neither hot or cold
ANSWER : If the A/C system is full and pressures are reading correctly, and the cooling system is in proper working order (thermostat opens, no overheating, etc.), then most likely the problem lies with the dash. The climate control head unit may be at fault. One or more blend doors behind the dash may be stuck or broken.
