if you remove the glove box the heater fan can be removed with a twist . if the fan works on the bench from a car battery (if no battery try a battery charger ) put the fan back in place but dont use the car connection . Using new wire 10 amp rewire from car battery one wire to one side of the motor with spade connector and from the other side of the fan useing a spade connector take the other side to an off /on swich and you have a working fan use it till you can get time to get a better fix it works well for me if you can not get the wire through the bulk head i took the wire along the edge of the front wing it will not be notice all the best
