Smell from Heater
If the bad smell starts when you turn on the heater, then there is a good chance that the smell is coming from the heater. If you haven’t used the heater in a while, then the smell might just be dirt and dust burning off.
If that is the case, then it will go away after a little use. Once the dust and dirt have burned off, then the bad smell will stop. If the bad smell doesn’t stop though or if it occurs even when you have already been using your heater, then it is coming from something else.
One of the common other things with the heater that could be causing the smell is you might have gotten some plastic debris, such as a bag stuck in the heater system.
You should check under the hood, in the engine area, and up under your car to make sure that no plastic bags are stuck anywhere. A bag that is stuck could be melting as you drive.
There are a lot of plastic bags on the road, and it is easier than you might think to get one stuck up under your car. Outside of the burning smell that is annoying, it is important to get the bags removed as soon as possible because it can damage other parts of your car.
A plastic bag can get stuck in a fan or cause something to overheat, so if you smell burning plastic, then it is a good idea to check for bags.
Lastly, burning smells from the heater could be coming from a broken heater or another component near the heater. If you check for a plastic bag and don’t find it, but have a burning smell, then you need to take the car to a shop and have a thru inspection done.

If you have a burning plastic smell when you turn on something else besides the heater, then it is probably an electrical short. This happens when the plastic coating on wires, fuses, or other connections wear off or burn off.
The issue is with whatever system you turned on when the burning smell starts. For instance, if you start to use your power windows and the smell starts, then it is the window system that has the short.
The reason why these occur is that the electrical wires get hot when you use the components. This heat is hot enough to melt the wire coating sometimes, and this melting is the smell that you smell.
The wire coating is easier to melt as it gets older. This is especially true if the wire coating gets cracked or damaged. That is because the wires inside can be exposed to things that it is not supposed to and heat up easier or cause a spark.
The good thing is that if the burning smell is occurring from an electrical short, then all you have to do is replace those wires. The hardest part with electrical issues is tracking them down though.
That is why it is extremely important to pay attention to what you are doing when the bad smell starts. The better you are at paying attention to what system is causing the smell, the more money you will save on fixing it.
