Non-Dimmable Backlighting
WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
The power window switch backlight is a constantly illuminating bulb which illuminates when the ignition switch is in the RUN position. The generic electronic module (GEM) provides a ground path for the accessory delay relay to provide B+ to the power window switch.
