Heater problem
1998 Ford F150 V8 Four Wheel Drive Automatic

My blower fan stopped working all at once I checked the fuses and both are good, I checked for power with a volt meter on the fan motor with the switch on high no power, I check at the switch and no power. Any suggestion please.
Do you

Usually turns out to be the resistor, but where you have no power to the switch, check the blower relay behind the center of the instrument panel, and if that's good, check the grounds under the front passenger kick panel...

At this point you need to figure out why the relay melted, pull the relay center out and look at the wires, something is bare. And check those grounds I told you about!
