A/c blows hot air burning smell - 2002 Mitsubishi Lancer

have an accredited ac shop as an ac cannot produce hot air only cold air so that means that the ac is not working (leaks low on gas etc). The hot air is from the heater in the car and the smell is probably wire overheating or the resistors are burning.

Is the ac compressor clutch and pulley turning ?

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

Hi your valve cover gaskets need replacing .
The reason you smell oil burning is the residue of oil ,,that getting in to the spark plug recess holes .As the spark plugs get so hot , then the oil is burning off .The vapour is sucked in to your heater vants . I know i have just replaced mine,and now i have no smell ...

Sounds like the A/C compressor clutch has overheated and become inoperable. Open the hood, start engine, observe the compressor face. It should be turning and also see if that's where the noise and burning smell is coming from.
Good luck!!!

check for slipping ac drive belt ( smell and noise )

this could be a hole in an AC line trace or have the lines traced replace and replaced Freon

It sounds like the belt is slipping or maybe even the compressor is seized. Just check to see if the compressor is turning.

air conditioning pump drive belt is bad, needs replace

there,s a chance that your hot-cold air trap is not working
