Heated Seat Switch: Operation
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The heated seat switches receive battery current through a fused ignition switch output (run) circuit when the ignition switch is in the On position. The two six-position rotating-type switches provide a hard-wired voltage signal to the heated seat module to power the heated seat element of the selected seat and maintain the requested temperature setting.
There are three Light Emitting Diodes (LED's) in the heated seat switch. The first LED illuminates the heated seat symbol on the switch anytime the ignition switch is in the On position. The remaining LED's illuminate the numbers on the switch, indicating that the system is on.
