My heater/AC blower only hi for yr. Then quit completely. on 1999 Ford Contour

Only time it came on was at speeds over 50 for extended time.Some air at lower speeds but not much.

Asked by for the 1999 Ford Contour
these were bad to burn wires at the blower resistor. probably needs resistor and wires to resistor replaced. it is located below the glove box in the heater housing.
Thanks. .
