if you do your own repairs .make sure you have a test light and a volt
metor.
the next step would be check your flasher it could be haft dead.
also fuses can look good but also be bad. that is were your testing
equipment comes in handy. they also help to tell you weather you have a
broken wire or a bad ground.

When two seemingly-unrelated things aren't working, odds are the problem
is with whatever they have in common.  What DO they have in common?  A
ground point?  A single connector?

My left brake light and left signal don't work.  I changed the bulb but
that didn't solve the problem.    Fuses look fine.  What could it be?
___________________________________________________________

They are both the same bulb.     The turn signal switch on the steering
column decides whether to flash the bulb (turn signal) or turn it on
continuously (brake light).

1.)   Recheck the fuses.   Use a voltmeter to see that fuses have power.
2.)   Check the connection of the cable that enters the steering column.
3.)   Check whether there is voltage at the bulb socket when a friend
             presses the brake.

If none of these work, the turn signal switch probably needs repairing.

Good luck.
