Signal Click
 

I'm having the signal click noise come on when I'm driving when I haven't used the control for the signal. It does not make the signal LIGHTs come on just the click noise comes on and off completely at random. Before it wouldn't click while I was slowing down or parked now it clicks at any time.

From your other post, I see that you have a 2000 4x4. Having that information up front helps those of us that are trying to help.

A clicking in the dash like you are experiencing is typically caused by a fault in the contacts inside the multifunction switch (the stalk that controls the signals, hazards, wipers, and high beam functions). More often than not, it is just the hazard switch portion of the assembly which is at fault and this can be replaced separate from the fairly expensive multifunction switch assembly for just shy of $20. This is what I would recommend trying first. I believe that there still is a DIY article on this topic.
