Ceiling fan light gone haywire

I am new here,first post.I've searched everywhere for this scenario,with no luck.I have a Harbor Breeze cieling fan with 3 lights.The fan works,light does not.The sockets show 120v,screw a bulb into any of the 3 sockets and voltage drops to 0v on all 3.It calls for A15C bulbs,and that's what I have.Any ideas would be greatly appreciated.

How did you measure the voltage to know it went yo 0 volts?

Has it worked in the past or always been this way?

Actron multimeter red/hot on center tab of socket black/ground on outer rim/threads. Switch/pullcord on reads slightly above 120v,screw in a bulb to another socket,it goes to 0v.

OK, so you're still reading on an empty socket but noticing the voltage on that socket drops to zero if a bulb is put into another socket - am I reading that correctly?

It sounds like the bulb dimmer circuitry has failed.
