    Was the fuse bad, or did you just change it? Do you have voltage at the fuse, what about the blower motor? You may have to pull the plug on the motor, if it is drawing too much current, to see if you are getting voltage there. If so, is the blower motor properly grounded? You can pull the motor and hook it up to your battery and see if it is working, a couple of alligator clips and some wire. Just make sure you hook it up right ( positive and negative), it shouldn't really matter though, but just in case. - Steve

    same thing just happened to my dads plymouth. run the fan directly off the battery, just not for long if that works check contunity (resistance test) the wires to and from the controler the motor and the supply. if you didnt smell a burning smell before the motor craped out its probably just a bad connection.

    Just FYI, I've had a blower motor just quit..........like quit all of a sudden, with no friggin' warning, right in the middle of a Canadian prairie blizzard at -28C!!!!! Anyhow, enough crying- just wanted to say the fan motor could have just died.
