Hello Gilligan in Lousian
Thank you for choosing Just Answer
I can assist you with your question.
In answer to your question, the flasher unit is contained in the lighting control module, which is located behind the middle of the dash, right of the steering column, about knee high. I am attaching a drawing of its location.
Although I have had one or two go bad over the last 15 years, a more likely cu;prit is the multifuntion switch mounted on the steering column
The modules are 2 or 3 times the cost of the, switch, and with a minimum of testing we can determine just which component is bad.
Do you prefer to try some testing , or go ahead and replace the module? The procedure for replacing the module fairly straight forwards. Remove the panel that allows you access to the fuses, and the module is mounted above the accelerator pedal. Disconnect the 2 connectors, unbolt he module and slide it from the mounting bracket.
Either way, you can contact me here with any more questions.
