Are these for the buttons backlight, lcd backlight or both?There are small flat plastic things that look like washers on the back of the ACC. they have slots in them to allow you to turn them with a small screwdriver.
I replaced them with bulbs from Radio Shack and not the ones from Saab which are a hell of a lot more expensive.
have you changed the bulbs?I wish it'd be as simple as 1 bulb out or dead pixels . Both these are well known issues , but, my SAAB 9-5 wagon's ( 2000 ) climate control display was on for just a brief period and on just 1 occasion, thereafter, it has never really shone the way a display should .
I am not able to discern between dead pixels or loose connection or backlights out.
Dead Pixels : I can see shadows of display characters in full but faded . If it were dead pixels I would see incomplete characters. So not likely
Bulbs out : It has 4 bulbs . All 4 cant go out at the same time esp if it worked momentarily in the past- again that makes me keep this aside.
So what else could it be. Anyone experienced a similar problem and what was the cause & solution.
