Digital Dash light sensor

[Jeff Pereira]

Daylight mode -- or full brightness mode -- overrides the factory rheostat.

If memory serves me corrctly there are two photocells, but I think the one
you need to check is on the left side of the raised portion of the
instrument cluster -- very easy to take out -- it just "pops" out  -- mine
even does it all by itself.

OK, since nobody seems to have any troubleshooting tips, can the "electronic
eye" be overridden? Could it be removed/disconnected and have the system say
in daylight mode all the time? I could then dim the dash manually with the
rheostat (sp?). Anybody?

determined that my dash isn't quite working right. According to the manual
there is an electronic eye that detect light natural light levels and
adjusts the display automatically. When it detects low light levels it
automatically dims the dash and if you start the car in the dark it will
flash a green emblem on the dash to remind you to turn on your headlights.
But in my case it does this every time, and I've always thought my dash was
too dim in daylight. It seems to me that the electronic eye must not be
functioning properly and it "thinks" it's dark out and id dimming the dash
and tripping the warning light. I'd really like to get this feature working
right. Anybody ever had this problem? Anybody willing to suggest some things
to check to help troubleshoot this? Also has anybody successfully calibrated
their fuel range using the directions in the manual? Is it really as easy as
it appears?
