Rear defogger not working!

So I got the car 1 month ago and haven't noticed till now but the rear defogger isn't working.
I believe its the button in the middle of the HVAC, the other 2 buttons next to it do light up and work (the buttons with the snowflake and recirculation symbols), the rear is the only that doesn't light up. I thought it would only work with a certain mode in the left wheel or AC/Heat only, but after trying most of them and the light didn't come on I believe it's a problem.

I've read around and some people mention it's a BCM problem, or switch the fuse? Could somebody help me locate these fuses and where can I buy a new one, or does the car have spare ones?

Thanks in advance.

Alright will check this in the morning! Thanks for the suggestion.

By the way another thing I've noticed.

Today when it was dark out I turned on my car and headlights, when I press the rear defogger button the lights/rest of car looks like it "loses power" for 1 second, like the lights dim a bit including headlights and dome light, then it goes back to normal. I pressed several times the rear defogger and everytime it causes this effect. I feel like it tries to push energy through a "broken" circuit or something like that. Maybe the power sent to activate that module gets nowhere and it just wastes battery on the attempt.

Anyone had this issue?

That's pretty normal. Try pressing the window buttons to the up position (even though they're up), and you'll see the same effect. Do this with the car running of course.

Your defogger is working that's why your headlights dim. Lights burnt out on hvac.
