I have been having this weird problem recently:
Sometimes when I drive, the right turn signal indicator on the dashboard will be on solid. The turn signal itself won't be on, just the indicator is on. If I use the right turn signal, the indicator will blink as usual, but then when I turn it off, the indicator will glow faintly and then gradually brighten to be on solid. Also, it is apparent that on drives when this problem occurs, when I use the right turn signal it blinks much more slowly than the left turn signal does.
Other times when I turn the car on, the indicator stays off and everything seems normal. I haven't found any correlation with any of the other settings for my lights or display brightness or anything.
This is a 1996 Oldsmobile 88. Obviously, something in the circuitry is going bad, but any clues exactly what might be wrong?
