both motors/parking brakes
are properly inserted.

motors/parking brakes for
corrosion or damage.
2. Check
both motors. Unplug the
motors/parking brakes and
measure the connection with an
Ohm meter. If the resistance is
more than 1 Ohm or less than
100 milliOhms, then the motor is
defecktive.
3. Check the resistance between
the motor and its housing by
means of an Ohm meter.
Measure every contact between
the motor and its housing. If the
resistance is less than 1
MegOhm, the motor is defective.
NOTE: If one motor is faulty, the
other one could also be defetive.
