At night, when I flip my lights on, at random, my two switches for the fan speed ad temp do not light up..that is..until I smack them, and they turn on.

Any idea why this happens? It does not bother me that they don't work but I want to sell the car, so i need everything working, ya know?

Thanks!

 

loose bulb?.....open up the dash and check it out

 

How to I take the dash off? I was thinking of painting it while its off..
