8P - 2 POWER LOCKS
B R
POWER LOCK MOTOR
Before you proceed with this diagnosis, confirm
proper switch operation. See Power Lock Switch di­
agnosis.
(1) Check each door motor for both lock and unlock
function while operating the switch. If both motors
are inoperative, go to step 3. If one motor is inoper­
ative, go to next step.
(2) Once it is determined which lock motor is inop­
erative, that motor can be tested. Disconnect the wire
connector at the motor. Apply 12 volts across the mo­
tor terminals to check its operation in one direction.
Reverse the polarity to check the operation in the
other direction. If OK, repair wire harness from the
motor to the switch as required. If not OK, replace
the motor.
(3) If both motors are inoperative, the problem
may be caused by one shorted motor. Disconnecting a
shorted motor will allow the good motor to operate.
Disconnect each motor connector, one at a time, and
re-check both lock and unlock functions while operat­
ing the door lock switch. If both motors are still in­
operative after above test, repair wire harness
between motor and switch as required. If disconnect­
ing one motor causes the other motor to become func­
tional, go back to step 2 to test the disconnected
motor.
