Power Folding Mirrors

WARNING: This page is about a different car, the 2008 Cadillac CTS. However, it is still accessible from the selected car via links, so may be relevant.

Export vehicles may also have the power folding mirrors feature. The operator may simultaneously retract both mirrors to a fully folded position, in which they are closely tucked in and parallel to, the front door windows, or simultaneously extend both mirrors to the fully unfolded position for normal everyday use.

For this feature, the driver door switch assembly (DDSA) has an additional power folding mirrors switch built into it and, each mirror contains an additional power folding mirror motor. When the switch is activated to fold the mirrors, the switch contacts close, the DDSA interprets the signal input, and sends the command on to the driver door module (DDM) and the front passenger door module (PDM). The DDM and the PDM then each apply battery voltage and ground to the appropriate circuits of their respective power folding motors in order to retract both mirrors. When the switch is activated to unfold the mirrors, the door modules reverse the polarity of the voltage and ground applied to the reversible folding motors in order to move both mirrors to the fully extended position.

The power folding mirrors switch is activated by momentarily pressing the switch button. Each subsequent press will activate the mirrors to the opposite function of the preceding press, i.e. if the mirrors are currently folded, the next press of the switch button will cause them to unfold and vice-versa.
