The transmission for the 1996 Chevy 3500 could be jumping from overdrive for several reasons. The transmission could have a vacuum or electrical problem causing it to come out of overdrive. Or, there could be an internal valve problem causing this to happen.
For safety reasons, you should fix the problem so that you blinkers work correctly. This is a fairly common problem and the cost to repair will likely be minimal. For inspection purposes, however, your blinkers only need to work correctly during the inspection.
The light is flashing because there is a problem. The problem will need to be diagnosed and repaired to stop the flashing.

The problem could be that your flasher switch is going out. I had the same problem on my 99 blazer. It sounded like a bee buzzing in my dashboard. Had the switch replaced and problem was gone. Hope this helps.

You have a problem with the memory card.
Check bulbs Check flasher Check fuses
There isn't a separate fuse for the blinkers... they share a fuse with other lights. If no other lights are out, then you're looking at a different problem... might be a bad switch, might be faulty wiring.
These transmission are rear wheel drive 4 speed automatics, that are all computer controlled. Common reasons for the overdrive light flashing are the external sensors on the vehicle like the throttle position sensor or vehicle speed sensor quite often go bad, causing these symptoms. Always run a scanner first to see if a sensor is causing your problem.
