C7WY-13A366-BS - Tail light sequencer from Cougars Unlimited

About 8 years ago I installed a C7WY-13A366-BS device on my 1967 Cougar XR7. The device was simple to install and worked perfectly right out of the box. It continued to work perfectly for about 5 years. About 3 years ago it the tail lights stopped sequencing. Only the inside tail light (nearest the license plate) now blinks, on either side depending on the selection of the left or right option on the steering column. The car has always been garaged and less than 1000 miles on it since installing the C7WY-13A366-BS device.

My questions are these:

  1. Is their some way of me checking this device to see if in fact that it is working correctly?
  2. If not, is there a way for to have this device checked to see if it is in the proper working order? I am willing to pay a fee to do so.

Thanks in advance,
