Hey just wanted to chime in here...I had a similar problem on my 2013, found my 50A fuse for high speed fan blown. I replaced it, didn't think much of it. Then the new one blew, and I realized something was strange. Turns out cooling fan resistor, located on the top part of the fan assembly, which works for the "low speed fan" circuit, was bad. Resistance was infinite (wide open). This was causing the fans to not operate at low speed. My thinking is the high speed fan circuit wasn't designed for fans to start up from a standstill to high speed, and it pulls more than 50A to do so, blowing the fuse occasionally. So my fans were either off, or high speed. Every time it would spin up, the engine idle RPM would dip low, headlights would dim for a second, etc. In hindsight this makes sense, because it was pulling way too much power to get the fans to start from still to high speed. Another thing that's also better now, is that my A/C used to not blow cold, unless I was moving. Now when I turn on the A/C, the low speed fan kicks on, and it feels nice and cool even when my car is stationary. Lesson is, low speed fan not working can cause high speed fuse to blow. Resistor is only used for low speed fan circuit.
