Burning smell when front defrost is turned on - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Is anyone else getting a strong burning smell when they turn their front defrost on? I've got ~4K miles so I'm pretty sure it's not the normal break-in burning smell.

I have noticed this a couple times, but it seems to have subsided in the last 2 weeks. Still monitoring it though.

I get a burning smell through my HVAC from this if the car is not moving (until it burns off).

mine had smelled like burning rubber....haven't smelled it since it was in for new fuel pump. Crickets are back after 1 week so I can only imagine the unidentified burning smell will also return. (I don't think they are related at all) just odds of reoccurring issues runs high. =)

Yup, I have it. I think its the AC rather than the demister particularly.

Hmmm, haven't turned my AC on in a while - will try and see if that causes the burning smell also.

my old tc had a horrible burning smell when i used the defrosters or heat. it was as if something went down through the vents and died/got stuck/whatever. I had to spray a little lysol down into the vent once in a while with the fans on to make it smell better.

Yeah, I get a smell when using the defroster or the defogger... so pretty much every day..

jlu · 03-03-2013, 05:36 PM

I got it with the AC also - think I'll ask the service department guys to take a look when I take it in for 5000 mile service.

Keep in mind if any oil is spilled even a little drop like let's say around the filler cap it could run down to the exhaust manifold after heating up and it takes quite a bit to fully burn off synthetic oil. Had fun chasing leaks on my sw20 I had one that was a very slight drip from the turbo charger oil return line it was only a droplet but it would pool heat up after a drive and drip onto the down pipe. I would park let it cool and then heat back up and drip after a drive keep in mind turbos also generate more heat than an n/a engine.

I also noticed a burning rubber smell with the heat on. Only noticed it a couple of times yesterday while stopped at a red light. Drove it today with no smell. Its not from oil or any other fluid as far as I can tell (no leaks) It is a burning rubber smell. Not as bad as a burn out, but not normal smelling. It is coming out of the vents with the heat on. Im guessing blower motor problem.. If it gets any worse I will be digging into it myself. I HATE dealerships! They work quick, not properly. I work in a shop and have seen some brutal dealship work!

How many miles??? You would be surprised how many different burning smells a brand new car will generate.

86KEEBS · 03-03-2013, 08:53 PM

6000 kms

I think it's a good possibility
