Welcome to the forum, I'd have to check voltage and ground at the blower motor. Could be faulty blower motor. Also, check fuse 64--30 amp in under hood fuse box. Use a testlite, the circuit goes hot when you turn on the key. The lower speeds on the blower motor, are controled on the ground circuit, through a resistor block and blower switch. Max speed doesn't use a resistor.
