You have a short circuit in the HVAC electrical system and a wheel speed sensor that needs to be replaced, Usually when the heater fuse pops the blower motor resistor or the motor itself needs to be replaced. Here is the location so you can swap them out which should fix the problem. Check out the images (below). Let us know how it goes

Suggested Repair

Repair the short circuit in the HVAC electrical system and replace the wheel speed sensor. Because the heater fuse keeps blowing, replace the blower motor resistor or the blower motor.

Conversation Summary

The owner reported that the ABS light came on, traction control stopped working, and the digital heater/AC was stuck on low heat with no display. Replacing the burnt heater fuse caused the fuse to blow repeatedly. The expert diagnosed an HVAC electrical short and a faulty wheel speed sensor, and advised that a repeatedly blowing heater fuse usually requires replacement of the blower motor resistor or blower motor.
