The only thing electrical that turns on, inside of the car when the air conditioning is turned on, is the blower fan.
Do you experience this smell when you turn on the heater? The defroster?

Post a vid.

No I don't think so since I put the heater on low for like 10 minutes. It used to throw cold air now it's like a mix between hot and cold I don't leave it on because the smell scares me

Could it be antifreeze that you're smelling?

Is your thermostat working correctly? The absolute worst thing that could send out a burning sent would be your heater core

I think it is because the car doesn't overheat

No it just smells real bad. Idk if you have ever used a vacuum and the belt goes bad and it starts heating up.... Well that's the smell

Oh yes! I know what that smells like..
Turn on the air with the hood opened and make sure that the compressor is not frozen up when the air conditioning compressor clutch is engaged.

I'll look into it. Could no freon cause this symptom

There is a pressure switch in the system that prevents the a/c clutch from engaging if the pressure is too low from not having enough Freon.

Clutch? Or is it called compressor cause that thing won't move when ac gets turned on

The pulley on the a/c compressor should spin freely, if you were to take the belt off.
Inside of that pulley is a magnetic clutch that engages the a/c compressor when you turn the hvac control inside of the car to a/c.
If your compressor is seized up for some reason, the a/c pulley will STOP and the belt will just slide over that pulley whenever the a/c OR the defrost is turned on.
That could be the smell that you're experiencing.
I would expect it to squeal as well, but it's something to look at...

It does squeak on start up and I thought that was strange since the belt is new. Didn't make any noise when I popped the hood though. I'll see how much a mechanic will charge and if it's too much it will be a fun diy experiment.
