Display lights not working
 

My dashboard lights don't always work and not always fully. The lights on my display work from the speedometer to the right with a little hit on the top. and sometimes they don't work at all. The lights on the climate control don't work without a little tap either. Any ideas?

I have a 1992 300D and some of my interior lights didnt work. Took my instrument cluster out and found a four prong wire just laying in there. Pluged it back in and lights worked. Maybe yours is not pluged in all the way. Take a look.

Thanks I take a look.

So before I decided to pull my dash out. I decided to play with the Rheostat and as I turned it form high to low and low to high the lights would flicker on and off. Is this an indicator to my problem. Is it just a bad rheostat? I thought I remembered reading a thread about bypassing this...
