    First post on these forums but in the last two years you guys have helped me solve so many issues with my car so I hope this is one of those times.

    Scion TC: 2013 - automatic

    I have never had any issues with my ac/heat in the 2.5 years I've had this car. Today I turned on the AC and I hear this very high pitch spinning noise coming from the far right passenger side AC vent and zero air is coming out. I had my music turned up and I hit the heat on and noticed a burning rubber/plastic smell and immediately turned it off and the music. When I tried it again I noticed the same whining/high pitch sound and again, no air.

    After 30 minutes of internetting this issue, I assume it is the blower? I definitely hear something spinning so that makes me think the fuse is okay? I live in the woods so any number of things could have been sucked up/caused it to jam. I'm so mad I had my music on because it was cranking for a solid 10 seconds and I 100% smelled something burning.

    Some videos I've seen you hear a knocking noise and it was something rattling around in there but there is zero air coming out. I'd love to hear what you guys think and I am pretty sure my brother and I can take it apart but based on the videos I've seen but I'd love to hear your take on it. Thank you.

    yup it's definitely the blower motor/fan like you're thinking. Take it out and see if anything is down in there. If you haven't replaced your cabin air filter lately, lots of junk can fall down in there. I wouldn't keep trying to use the blower fan since the smell sounds like it is stuck and you'll burn it out if you keep trying to use it.

    If getting your brother to help, helps you then great. But it really doesn't take more than 1 person to remove the blower fan, couple of bolts (3), disconnect the electrical connector it comes out. I know, easy to say when I've done it before.

    If you do need a new fan motor, TYC makes a really good one, can find it on amazon. When my tC1 went bad (about 3 years in), I found toyota wanted like $160-200! for theirs.. TYC was like $35-40! Been working great ever since, even puts out a little more air than the original!

    Let us know how it goes.
