L turn signal intermittent

[Jeremiah Curry]

Howdy all,

hope you can help me figure this one out.  Car is a '91 200 20v and the left
turn signal has started working intermittently and the problem has become
worse lately.  At first the signal would click twice as fast as usual, but
the lights wouldn't blink.  But lately when I turn on the signal it just
makes an awful buzzing noise and the lights don't blink.  Noise seems to be
coming from under or behind the dash.  Maybe a relay?

Thanks in advance for the help,

Jeremiah
