C4 Corvette Question

[Als 70 L78 Nova]

First of all, I know it is not a supercar and I debated about even posting here for fear of being shunned. However, after a week on the Corvette forum without even one response, I have decided to give it a try.

I took a 1988 Corvette convertible in on a trade. I would like to let my daughter drive it but I first need to get the car inspected. Everything works but the brake lights. The center brake light does work. I have checked the bulbs and they are fine. The blinkers and running lights all work. Any suggestions as to what the problem might be? I changed out the brake light switch and the flasher today but it did not make any difference. The middle brake light worked but the outside ones did not. I did notice that the little resister (?) was broken on the brake light switch cradle. I forgot to mention that the four-way flashers also do not work. I wonder if it is all related? I have attached a photo of the resistor. Any help would be greatly appreciated by me and my daughter.

Thanks,
