I am sorry for the long wait
when the right signal does this does the right signal stay lit up in the dash solid ?
the odds are and is very common if it is just the left and not the right doing this and when it blinks the 3 times before its tops and all the front and rear signals bulbs do work when it does blink the 3 times that this issue will come down to a bad turn signal flasher module located behind the drivers side dash fuse box is bad
if you remove the panel under the steering column under the dash called the knee bolster behind the fuse box is the flasher module as seen in this picture
replacing that module should correct this problem you are having
