Blower control and headlight association

[JakeLasVegas]

I have a 97 Grand Prix with 138,000 miles. The car runs great, but lately the blower will quit at random times and if it happens at night, the headlights will go out too. If I turn the blower switch to high, the blower works and the lights come back on. Could this be a HVAC/daylight running lights fuse that opens up temporarily when it gets hot? Please help. Thank you.

But in all seriousness, it sounds like a bad ground somewhere.
