Ceiling fan wiring driving me CRAZY!

Please help!! I have a ceiling fan that has a double light switch at the wall and was working fine until last month. The light went out, but the fan continued to work fine (of course I changed the light bulb!). I have taken off the light and have been trying to fix this thing since. Here's the main problem: I thought perhaps the light fan switch had burned out so went to replace it-- bought a new one that has 2 black wires coming from it. Went to replace it and the one in the fan only has one wire coming out of it that went to the blue wire coming from the light socket. So where does the 2nd wire go? The wires in ceiling fan include 2 coupled red wires, 2 coupled orange wires, 3 coupled grey wires, 3 coupled brown wires, and 3 coupled white wires (where the white wire coming from the light socket is attached). It seems I can't post pictures, but please if you have any ideas let me know what I should try! I've been assuming it's something in the ceiling fan, but could it also be something to do with the light switch at the wall? Thank you for any help!
