2000 maxima se- dash lights where temp control is only half illuminate?

I've been told by a dealer that the lights just wiggle loose and only need about a half to quarter turn to start working again. Conveniently, they quoted me $150-200 to fix them. I may try pulling the unit and seeing what I can do myself because it looks like trash, but it isn't worth $200.

Like the other answer, sometimes they wiggle loose or burn out. They are very easy to replace, but the bulbs are costly, about $18.00 each. I bought used instrument panel from junk yard, $75.00 and took bulbs from there (has about 14 bulbs in it and used more than 4 bulbs from it which equalled the cost of the panel). Take out instrument panel and replace them where they are burned out. EASY.
