The cause for a turn signal flasher to keep clicking on a 1999 GMC Jimmy is a bad flasher unit. Replacing this with a new flasher unit should solve this problem.
Try replacing the turn signal flasher sometimes a near defective one with cycle
Yes.
You need to replace the turn signal flasher; turn on the left side and follow the clicking sound. Even though one side works, a faulty flasher can cause this problem.
A clicking noise from the dash on a 2003 Mercedes Benz might be the flasher for the turn signals. Sometimes the flasher will make a clicking noise if it is about to go out, to let the driver know it is time to replace the flasher relay switch.

Old answer: Could be turn signal or hazard flasher. Additional answer: I had a similar problem. The short answer is that a factory recall may fix it. See my long answer at the link below. http://markdionne.blogspot.com/2006/11/2000-vw-gti-clicking-noise-behind.html
The most likely cause is the turn signal flasher.
Its probably a bad flasher or sometimes a bad bulb can cause that to happen.
where is the turn signal flasher on a 1986 cadillac eldorado Rplace Turn signal flasher.Be careful cause ther is also a Flasher for the hazards,so make sure u say turn signal flasher and not flasher.These are two different plug type fuses.Around $8 to $15 bucks each
Try checking the turn signal flasher. Not to be confused with the hazard flasher.
If the bulbs are good buy it just will not flash the flasher relay is defective. Replace it.
One of four things can cause a turn signal not to work. Either the turn signal switch assembly, a bad bulb, a bad fuse, or a bad turn signal flasher.
