2016 Toyota tacoma issue

So I'm having a little issue with my truck. I keep blowing the fuse that controls my heater, windows and I get the air bag and tire pressure symbols on my dash...how do I figure out what the hells causing it? I haven't changed or added any lights or anything different to it, just started happening a few days ago and it's not doing it every time I drive it. I've blown 3fuses in the last 3 days.

 

Sounds like the heater is drawing to much current possibly a bad transformer .

 

Or…. You have rodent damage.

 

Which fuse is blowing?

I'm assuming it's either ECU-IG No2 (7.5A) or IG1 No2 (10A)

Need to take note of what you have turned on when the fuse blows like does it only blow with the A/C on.
