2018 eco burning smell

I’ve got a 2018 3.5 4x4 screw. A few days ago I noticed that when I start my truck, there’s a slight burning plasticy smell coming from the HVAC. It doesn’t last long, but it worries me. I turned the truck on this morning and opened the hood to smell around. Nothing on the driver side, front, or around the battery. The smell seems to be radiating from the fuse box. I took the cover off the fuse box, and nothing feels hot but the smell did get stronger. I’m gonna try and look it over with an infrared thermometer later this afternoon if I can find one.

yes, I do. But I’ve never used it.
