DESCRIPTION & OPERATION
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery. |
Each outside mirror has 2 reversible motors: one to adjust the mirror view up and down, the other to adjust the mirror view right and left. The driver operates 4 switches that control the polarity of the voltage to the motors. The mirror select switch directs these control voltages to either the right or left outside mirror.
