heated/cooling cupholders not working

Today I actually bought a coffee and I wanted to use my heated cup holder and its not working at all.

When you push the button to heat, the light on the button switch turns red and the cup holders light up red.

when you push the button again for cooling, the little light on button turns blue and the cup holders turn blue.

Nothing is working, actually on the button switch the light remains red and nothing happens. Feels like something shorted out.

any idea what to check for? is this still under factory warranty ? my ML is 3 years old and has 30,000kms (18K miles). Canadian model.

Your vehicle is still under warranty. If I were you I'd take it to MB dealer and have them check it out.

It might just be a fuse... that's the first thing I would check. This being said, if it is indeed a fuse, it would be nice to know why it blew.

My cigar lighter [cell phone charger] went out. Yes , it was a fuse. Under the rear driver side floor.
