The turn signal relay is constantly clicking on my 2000 GMC Sierra!! Yes the turn signal is off! Sometimes it is constantly clicking. Sometimes only intermittently. Tried replacing the turn signal relay but the new one clicks even more! Checked all the fuses. Any ideas what is causing this before I lose my sanity?

Probly the signal switch itself

Do the turn indicators on dash come on when it happens? Can you make it start/stop by wiggling the hazard switch? I'll print the schematic tomorrow, pm me if you want help.

No turn signals or hazards come on. No amount of playing with the hazard button, turn signal switch, steering wheel adjustment or just banging it with my fist will make it start or stop! lol Was hoping there might be some simple solution because the turn signal switch is +/- $175 plus labor! Ouch!

Pull the relay and use hand signals.

Sounds like a short in the M/F (Multi-Function) switch to me.

Bang on the steering column continuously for a longer period of time from different directions and much harder then you have in the past.

when turn signals blink faster than they should
then its a bad ground for sure...

maybe one of the wires insulation got exposed by rubbing

so you can buy a 15 foot length of wire that will reach
from the switch to the tail light and by pass the original
to see what changes... if it goes back to normal
then you know that wire is grounding out somewhere.

Was the "relay" you replaced the turn/hazard module under left side of dash?

Here's a wiring diagram if it helps, let me know if I can help.

Yes it was the relay under the dash. New one clicks more than the old!!

And new round of banging on the steering column was unsuccessful!!

The Hayes manual has the procedures for testing the signal switch module and removing the steering wheel. If you don't have steering wheel puller Autozone has loaners. The manual has a pin diagram to test the multiple switches with an ohm meter, replace only the defective switch.

The key ignition off when you get the clicking? Because it could be a faulty emergency switch causing the relay clicking. Unplug the emergency switch before doing anything else to see if the problem goes away

I watched a YouTube video showing how to replace the signal switch. Seems fairly straight forward to replace it. But a new signal switch is well over $300 at Advance Auto! I will try tysdad115's diagram after xmas and trace the wires for a short. Then the junkyard after the holidays and try and pull one maybe. Definitely not in the budget right now! In the meantime I just turn the radio up until I can't hear it!
