I have replaced the resistor pack and pigtail, thermostat, flushed the cooling system, replaced a cracked coolant reservoir tank, inspected hoses, and I keep blowing a 50amp bus fuse... the fan(s) will still not come on. And I Know the fan is good because I used a jump wire to the battery and it came right on. I am so at a loss... this is my only car and I need to get to work. So far all I can do is drive with the heater on full blast... which sucks in the California desert in the summer let me tell ya!!
