Hot plastic smell

When I am stop at a traffic light or sitting with the car idling I am getting a smell of hot plastic coming from the AC vents. Any suggestions?

RE: Hot plastic smell

Oil leak in the engine compartment, burning off on exhaust > gets drawn into the ACC via the grid just in front of the windshield, Really only noticeable at a stop or stop & go traffic.

Check it out...

RE: Hot plastic smell

Have you put new brake pads on in the last few weeks? That smell was brake pads on mine. When the protectant is 'burned' off, it will go away.

Look for a plastic bag or such under the hood. Got one underneath the hood of the Porsche on I95. Got off for fuel and it stunk like Plastic. Dumb but can happen. ALSO look for a vacum tubing touching something hot. Ends are rubber but the tubing is plastic.
