Intermittent ground can certainly do that. But I would not expect both sliders to have a common ground. Possible, but no real reason to I can think of.

I would first check to verify whether you have voltage or not to the lights. Good voltage but no light, then bad ground does become more suspect. No voltage then troubleshooting starts in the other direction.
