Burning plastic smell when cold out run heater and fan inside car and out


Are you loosing radiator fluid. sometimes the heater core will rupture and you will smell burn odor. also check for strange rubbing sounds or screeching coming from the blower fan motor. or engine exhaust manifolds are hot when car is on, make sure nothing is leaning on them which will cause a burn odor. Any odor coming from outside will find it's way inside through the fresh air vents.

How do I fix the heat


You have one of two problems. The heater core is plugged /
restricted or there is an inoperative internal blend door motor problem. Start the vehicle and let it reach operating temperature. Feel the hoses under the hood that go into the heater core. They should be close to the same temperature. If one is hot and the other luke warm/cold.... the heater core is plugged/restricted. If both hoses are near the same temperature, suspect a defective/non operational blend door motor that controls heat/cold/airflow attached to the heater box assembly

Car heater blowing cold air and rubber burnning


If your heater is spraying a light mist through your vents it could be your heater coil. Mine did the same thing, smell rubber burning, then started a light mist through the vents. If you don't get that checked out, it could mess up your water pump and possibly your engine

Not Overheating, Smells like really hot antifreeze after I drive, a/c ok heater heats but when stopped air gets cold...stummped..thermostat?, Leak?


check your hoses and make sure its not getting low because when it gets low the hoses can get hot enough to expand and spit out antifreeze without overheating

1997 blazer,heater bad smell when on


Is it a bad smell or a sweet like maple syrup smell. If its sweet you got a coolant leak probably heater core. Bad smell possible causes burning something up. I would run some water in the in the air intake below your wipers just to see if it changes. Not much but a little. Better or worse in cold tempers. Hwo about when the car first start or has run awhile does the smell get better or worse. More feed back please.

Mazda eunos leaking cold water, engine running hot and smells like burning rubber, temp gage is not showing a problem. Could it be the themosat?


Unless your gauge is faulty you engine probably is not overheated. Any vehicle engine at normal operating temperature is hot. I'm guessing but I bet your normal operating temperature is about 185 degrees. You say it is "leaking cold water". Were you using the air conditioner when this took place? If so that is normal condensation. As for the burning smell I would look at the exaust area to see if a piece of trash has caused it.

2003 Saturn, DOHC V6, burning smell in interior after car warms.


if the smell only comes on when the heater is on try pulling the blower motor mice like to build nests in the blower motor housing.

Heater Problums with the smell of burning Antifreeze.EXTRA Detail


Hi!

I really feel you could be losing a small amount of coolant from the heater matrix/core.

It appears we have an Air lock scenario due to this and you will need to perform a system Bleed.
Park the vehicle on level ground, when cold remove coolant filler cap, start engine and leave to idle, turn heater on full and blower to max. When engine reaches operating temperature watch and listen near coolant filler, keep clear as gurgling and hopefully a boil over should occur. Top up with very warm coolant and wait as it may do it again.
Check for heat inside vehicle if warm replace coolant cap but keep an eye on temperature gauge as the ~Air lock may have moved on from heater matrix/core so proceedure needs to be carried out again from COLD.
Also with your temp gauge reading 1/2 this is normal, possibly the core is blocked or as already suggested leaking, a Radiator sealing additive might help BUT it may be the cause of your cold/warm air?
TOO MUCH SEALER blocking the Matrix/Core?
I hope all this helps!
