I think the auto dimmer device is electronic, in fact I think it is called the "autronic eye" or something similar. At any rate, if it doesn't work and the wiring is good from it to the light switch to the lights without any breaks, shorts, or opens then the device will most likely need to be repaired. People do that but it isn't cheap. Someone on ebay has a store that does it. There are others I am sure.
