weird 'turn signal' clicking sound

[e30m42c92]

hi everybody...

From yesterday I am having turn signal sound problem.  I have searched whole posts, but I even couldn't find any similar problem.  

When I turn the ignition switch on I continuously hear 'clicking sound' like when I turn on the 'turn signal' even though I did not turn the turn signal on.  Sometimes the clicking sounds go faster and sometimes go slower.   It happens until I turned engine off and turned the ignition switch off.  Curiously, when I turn on the 'turn signal', the sounds go normal clicking.  This is very weird case and bothering me while I am driving.  My question is (1) what's the cause of clicking sounds, (2) do I need to replace 'relay' for the turn signal?, (3) if it is the case, where is the relay?  Is it located inside of the fuse box?,  (4) or do I need to replace whole 'turn signal assemble'?

bulb is going bad or is out. check your turn signals in the nose.

First of all, thanks 4banger.  I checked the bulbs, those were ok.   I wonder how the clicking sound goes on (sometimes very fast) even I do not turn on the signal.
