Signal Flasher! BAH!

I don't know if it's related, but around the same time my signals stopped working my overhead light now doesn't work when I open my drivers side door. Funny thing is, it still comes on when I open my passenger side door. I can also turn it on using the dash control. There is also no door chime with it open. Is this just another unrelated thing that's wrong with my mustang now? Or could the two be connected?

Thanks. That's the replacement flasher that I bought. That's exactly what i've been looking for all under the dash, but still no luck. I've tried hard enough, I think I'm going to end up taking it in to a shop.

I've tried tracing some wires that were light blue, but to no avail. I'll update you guys when i've solved the problem, cause i know somebody is going to find that flasher and it's going to be in plain view. Maybe I need glasses
