Description And Operation: Operation
The power mirror switch:
- Circuitry within the driver side front door power switch module is connected to battery current through a non-switched fused B(+) circuit in the under hood Power Distribution Center (PDC).
- The power mirror switch circuitry also has a path to ground at all times through a take out and eyelet terminal of the body wire harness that is secured to the body sheet metal.
- These connections allow the power mirror switch to remain operational regardless of the status of the ignition switch.
A latching push button power mirror selector switch has three positions:
- L (left)
- R (right)
- N (neutral)
After the right or left mirror is selected, one of the four directional arrows on the momentary power mirror control switch disc is depressed to move the selected mirror up, down, right or left. The power mirror control switch directs the appropriate battery current and ground feeds to the proper horizontal or vertical motor within the mirror articulating mechanism of the selected power mirror.
The power mirror switches as well as the hardwired input and output circuits of the switches may be diagnosed using conventional diagnostic tools and procedures.
