Replace yous blower motor the motor itself probably has a short in it

Reach under the glove box. Close to the centre console there are a number of wire connectors. With the engine running, move the wires slightly. If the blower comes on in response to moving the wires, its possible that there is a poor earth connection.

It could be the fan or the A/C control fan switch is bad. I see this all the time.

if the blower motor is pulling to much current it will fry the resistor and the connector, as above wiggle the blower motor resistor wiring connector around probably got real hot and melted the connection...( if it turns back on ) ....you will need to replace the blower motor the resistor and cut and splice a new connector in it's place to correct the problem correctly

I have a similar problem my plug melted on resistor and i cut the plug extended the wires and soldered directly to the terminals did away with the connector completely. When i hook the battery back up the blower motor came on without the Key switch on unhook the battery terminal and put battery terminal back on and blower motor now is not working again but did work for them, few seconds when the key switch was not on any help would be appreciated-------------------------------------- .
