Power Mirror Switch: Description and Operation

The power mirror switch has a right and a left position. Moving the switch to either of these positions changes the voltage path internal to the switch (changes polarity at the motors).

When the switch is moved to the LEFT position and mirror movement UP is selected, voltage is supplied through the P71 circuit and the ground path is through circuit P73. When the DOWN movement is selected, the power and ground are reversed.

If a LEFT door mirror movement LEFT is selected, voltage is supplied through the P75 circuit and the ground is passed through circuit P73. When the left door mirror RIGHT movement is selected, the power and ground are reversed.

When the switch is moved to the RIGHT position and mirror movement UP is selected, voltage is supplied through the P72 circuit and the ground path is through circuit P70. When the DOWN movement is selected, the power and ground are reversed.

If a RIGHT door mirror movement LEFT is selected, voltage is supplied through the P74 circuit and the ground is passed through circuit P70. When the left door mirror RIGHT movement is selected, the power and ground are reversed.
