determined, replacement should be made. If motor or wiring is defective, power rearview mirror can

not be operated in both directions; if the wiring is broken, no current flows through the motor, so the

power rearview mirror cannot turn in any direction. If the coil or the brush of motor is defective, the

power rearview mirror cannot turn in any direction either. It is impossible that the motor rotates only

in one direction.

※Reference: if the electric control device that changes rotating direction of the motor

(power window, motor circuit,

power rearview mirror, electric driven seat etc.

) can only

operate in one direction, it is mainly because the defective switch.

(2)

Power rearview mirror

on right or left side doesn’t work

The causes may be the defective switches of the right or left side, or may be defective

wiring or motor on the side that

power rearview mirror doesn’t work.

①

Remove the interior door panel on the defective side (to check the

power rearview mirror

connector

)

②

Remove

power rearview mirror wiring connector

③

Inspection of

power rearview mirror on the left side: if the right/left angle can not be adjusted,

after removing the wiring connector, connect a universal meter between the yellow wire and black-red

wire, no matter on the right or the left side, push the angle adjusting switch down, and voltage of 12V

will be shown (digital display). If voltage is shown, the switch and wiring are normal, the power

rearview mirror should be replaced; if no voltage is detected, check if the wiring is broken. If the

wiring is not broken, defective switch can be determined. If the up/down angle can not be adjusted,

connect the universal meter between the green wire and black-red wire, make the inspection as above

described and find out where is defective.

④

Inspection of

power rearview mirror on the right side: The inspection and decision are made in

the same way as that of the left power rearview mirror, but the color of the wiring should be noted. if

the right/left angle can not be adjusted, connect the universal meter between the grey wire and

black-red wire; if the up/down angle can not be adjusted, connect the universal meter between the

blue wire and black-red wire.

※

Reference: the color of wiring here mentioned is corresponding to that on the

door wiring side, not to that on the

power rearview mirror motor side.

(3)

Right/left angle or up/down angle can not adjusted on the both sides.

Almost all of this kind of problems is caused by defective switch. If the problem is not

disappeared after the switch is replaced, it may be resulted from the short cut between the

motor wiring and car body. After turning on the switch on, if the wiring that is short with

car body is connected to the positive pole, the switch is cut off due the high current

between the wiring and the car body. If only the switch is replaced without eliminating

the short cut, the switch will still be cut off. Therefore, under such circumstances,

remove the

power rearview mirror wiring connector instead of replacing the switch, check which

wire among the yellow, green, blue, grey and black-red wires is short with car body. That is, these

wires should be checked one by one with the universal meter. Find out the defective wire and fix it,

and replace the switch (in the off state)
