I have a 2000 yukon xl and the turn signal noise keeps clicking after I use the turn signal. The lights work fine on turn signal and hazards but it just keeps clicking long after the turn. Sometimes it'll stop on it's own if I fiddle with the lever or if I hit a bump in the road but there is no consistancy. I've replaced it with another switch (not OEM) but nothing.

Re: Turn Signal keeps clicking
There is a relay for the turn signal and hazards also check connections but the problem is easy it's the relay for the hazards making clicking after turn use same thing on grand am pull hazard button out on dash there is a green relay there that hazard plugs into replace it same with Yukon replace the relay

In these newer cars they have installed separate fuses one for each side see if that is the case, if it is problem solved. If not you will need to check the line with a meter to see if you have any power going to the light area . If that's the case hook a hot lead of the turn signal and trace it backwards. Have you also changed the flasher unit. If not try it.
When you touch the turn signal lever do you hear clicking noise befor u lift up or down if so then could be bad turn switch or just bad relay replace relay first if still doing it replace the switch get Haynes book to help with switch removal and install if relay don't fix it cause u will have to remove steering wheel etc to fix it if switch is bad
There is no adjustment. The park lights are on a different circuit than the brake lights.
Do you have a third brake light that works. Its also on a different circuit but works from the same switch. Do your turn signals work. They use the same filament as the brake lights.
Also, the brake light circuit goes through the multi function (turn signal) switch.
Since the brake lights and turn signal lights use the same filament in the bulbs, the brake light circuit will pass through the turn signal switch. When a turn signal is used it cancels out the brake light for that side.
Let me know if your third brake light and turn signals work in the rear.
Also, if youy have not already, check/change the bulbs. The type of sockets those lights are in also get burned so look at them well.
That vehicle has all three switches attached to the same module. Spray a little wd-40 into the flasher switch. Sometimes the slide on the flasher switch gets a little sticky and won't allow the turn signal to work independently. If that isn't the case, there is a repair kit for that available on ebay. the module of course costs around three hundred to replace but could possibly be found at a boneyard for much less. Also, check ebay for that module. Hopefully the WD-40 will fix it. Good luck.
check for burn out bulbs first = that can cause the flasher to do funky stuff. if that is not the case, then the actual flashing (forget the name...thingy) on the circuit board is fried and needs to be replaced (not a common problem) . another this could be that the signal switch itself is broken and constantly in the on position...
