The pull cord broke off inside the fan so I went out and bought a new switch and the problem is the old switch was set up like this' grey wire in 1 red wire in 2 yellow wire in 3 4 was empty and the black wire in c . The new switch has no c 'it has 1 2 3 and L So I put grey in 1 red in 2 yellow in 3 and black in L and it does not work. Went to a few stores and can not find a switch like the old one. Not sure what to do ' any help would be appreciated thanks.

What make is your fan?

I presume c = L and the rest are the same.
