Occasionally, on a clear, bright day, the headlights on my '98 Seville will be on and the result is a hard to read instrument cluster. Even with the dimmer turned to the brightest setting (fully clockwise), it's nearly impossible to read the gauges. If I turn the twilight sentinal off, the message center will read "Headlamps Suggested"!
In the past, I had other vehicles (including two Cadillacs) with the automatic headlamp feature, and the cluster was always readable even if the lamps were on during a cloudy day, etc. However; today it was not cloudy, and the headlamps were on!
I have the Cadillac service manuals (3) for this car, and although I have not read them from cover-to-cover, there doesn't seem to be anything relating to this problem (if it is a problem).
A friend suggested maybe the sensor was dirty, so I tried to clean it with a cotton swab; but, to no avail. Any suggestions other than to just not use the twilight sentinal feature?
