Power Mirror Switch: Description and Operation
CIRCUIT OPERATIONThe 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 P93 circuit and the ground path is through circuit P90. 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 P95 circuit and the ground is passed through circuit P91. 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 P92 circuit and the ground path is through circuit P90. 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 P94 circuit and the ground is passed through circuit P91. When the left door mirror RIGHT movement is selected, the power and ground are reversed.
