How do you troubleshoot and fix the right turn signal of a 1997 Pontiac Firebird Convertible that gets stuck and does not flash?

Change the blinker bulb for that side. It is a hit and miss though. If you change the front bulbs and it still doesn't blink you will also need to change the rear bulbs. The front bulbs are rather difficult to change from above the vehicle. You may want to get underneath and definitely during the day!!! THE REAL ANSWER!!!!!! This drove me crazy on my daughters car. It turned out to be the day time running light modual wich is located behind the radio. the conections were loose. when you turn on the right turn directional the front light would go out but the rear directional would work. listen closley behind the radio for a one click noise when you activate the right turn, and also a delay one click when you deactivate.
