How do i fix a fisher price power wheels jeep

If you have a volt meter, switch the volt meter to 12v, locate the motor in the back wheels and if you can see where the wires connect to the motor touch the terminals of the volt meter to the two connections and turn on the power wheels press the power pedal and see if you get a reading of 12v. If you can't touch the wire or where the wire connects try disconnecting the wires and testing it that way. If you have 12v at the motor then it seems the motor is shot. There should be two motors one fit each wheel and its unlikely that they would both go. If you don't have power at the motor try following the wires to the pedal and also the forward reverse switch. Test these in a similar fashion. Hope that helps
