If (big if) these are like the electronic modules used on Yamaha golf carts, these are NOT repairable. If you have RHOX turn signal stalk and RHOX cable assembly, you MAY be able to purchase an after market plug in module. Otherwise to only other option I have found is the Signal Dynamics modules (here is one supplier, but they have other options), Signal Dynamics Self Canceling Turn Signal Module - RevZilla
these are motorcycle turn signals, and care needs to be taken to make sure the existing turn signal switch is compatible with the proposed module.
I have done some research on this for both myself and neighbors, and it appears that several of the golf cart suppliers use CUSTOM modules that are not available online.
Hope this helps, send me a PM if you would like to discuss further.
