Hi there, i just changed the battery on my 2005 f150 and now the blower motor is now coming at all and keeps popping the 30 amp fuse. Have gone thru a few. Any suggestions ????

 

Try unplugging the motor and see if it blows. If it does, there's a short to ground in the wire from the relay to the blower. If it doesn't, disconnect the resistor and see if it still blows. If it does, there's a grounded wire to it. If it doesn't, the resistor is shorted to ground.
