Does it blow with the TVs unplugged? Sounds liek you may be drawing too much through that system. If it still blows with the TVS unplugged, you will need to trace out everything in that system to see what is shorting out. Could possibly be the plugs for power, sometimes they can short internally if there is too much pulled through them

That is possible. Try unplugging it to see if the fuse still blows. It is located near at the blower motor

Gonna have to isolate every circuit on that fuse and unplug them one at a time until you find the culprit. Have you looked a the wiring for the acc plugs to be sure nothing melted together?
