Try fixing them!
Many times step issues are a result of a bad ground under the step. There could be two grounds that needs to be cleaned up.
Yes, you can jumper the motor to retract the steps. Should have twelve volts on large red wire under the step. Locate the connector to the motor. Apply power and ground to the step motor. If it retracts disconnect power. If it does not retract reverse the polarity on the jumper(wire you used to connect power and ground)
BECAREFUL stay clear of mechanism.
DO not drive with step out. I found my step was out the hard way. Curb!
