Overheating and no power to climate control?

I have the car listed above that I just bought a few months ago. My front bumper was loose and while driving on the highway it fell off and dragged for a short time under the car. I removed the bumper and continued my trip. I don’t know if it happened immediately but about an hour later, I noticed I had no power to my heater or A/C. Figured it was a fuse. A few days later I noticed my car started overheating within a few minutes of being on. I have checked the fuses and changed the thermostat, refilled the coolant after changing the thermostat and still have the problem. Any idea what it might be? Thank you in advance.
