Turning Signal "Clicking" Won't Go Off

The clicking signifies that the relay is functioning. When you turn the blinkers off on the steering column; 1) do u still hear the clicking?;

Thanks for the prompt response...

2) The turn lights (both front and rear) only blink when the dash indicator is on (as normal).

Again, everything appears to be working fine. It's just an annoyance more than anything else, but I also want to make sure that something else is not wrong...

That is definitely an odd problem, sounds like the relay is staying on even when you turn the signal off.

When turn indicators, and signal lamps are off, and signal lever is left in the idle position, does clicking sound continue?

Try cycling the hazards. Next, locate the culprit relay, tap test it, then try reseating it. If it is indeed your turn signal relay, and it is clicking, your turn si gnal lamps will be illuminating. Jim

Yes, after the signal lever is returned to it's normal position (and the turn indicators have gone off), the clicking sound continues...

My guess is that it is not the turn signal relay, however I'm not aware of any other relay that operates at this frequency. All else fails, would disconnect neg Bat cable, then reconnect it after say, 5 minutes. Am curious as to make, model and year. Jim

I should have stated that at the beginning...sorry...

It is a '98 GMC Sierra C1500.

I did try cycling the hazard lights this morning. It did improve the clicking (it doesn't happen constantly now, it's more intermittent) but the clicking still does exist. FYI, the switch to turn on my hazard lights is also on the steering column (on the top)

Have u located the relay. Is the sound in the steering column, or underneath the dash. Also try the negative Bat cable.

I didn't get a chance to look at it last night, but will tonight or tomorrow...I was able to determine that the sound is coming from underneath the dash not from the steering column...

Should be a little silver cannister or a little black box the size of a quarter. While its clicking, give it a tap. If it stops, great, otherwise, pull the neg Bat cable and wait 5 minutes then put Bat cable back on. Jim

I was able to locate and replace the turn signal flasher relay. This did not fix the problem. The clicking still continues. I will try the battery cable thing this weekend. Thanks for all of your help so far and I hope you have a safe and happy holiday!

Is the one you changed, the one making the noise?

Replace the turn signal switch.

Yes the one I replaced was the one making the noise. I was able to remove the relay and the noise went away (of course, the turn signals didn't work at this point). However, when I replaced the module, I still had the same problem.

That would imply something is drawing power through it. The wiring usually goes from the flasher right to the signal light switch. I also think the hazard switch has a tag in there too.

I would be working that emergency flasher switch a few more times to see if it gets better or changes again. They made a bunch of bad emergency switches in the Jeeps of that age too so it would be my first suspect.

Might be. Something is definitely drawing current or partially shorting to ground downstream of the flasher, anyway.
