Glass Ajar Indicator: Description
A glass ajar indicator is standard equipment on all instrument clusters. See Fig 1. This indicator is located within the odometer/trip odometer Vacuum Fluorescent Display (VFD) unit. However, on models equipped with the optional Electronic Vehicle Information Center (EVIC) the glass ajar indicator in the odometer VFD is electronically suppressed so as not to duplicate indications that are provided by the EVIC.
The glass ajar indicator consists of the text "GLASS", which appears in place of the odometer/trip odometer information in the odometer VFD unit. The odometer VFD is soldered onto the cluster electronic circuit board and is visible through a window with a smoked clear lens located on the lower edge of the tachometer gauge dial face of the cluster overlay. The dark lens over the VFD prevents the indicator from being clearly visible when it is not illuminated. The "GLASS" text appears in the same blue-green color and at the same lighting level as the odometer/trip odometer information when it is illuminated by the instrument cluster electronic circuit board. The glass ajar indicator is serviced as a unit with the VFD in the instrument cluster.
