I have a 2010 chevy aveo. The signal relay for the turn signal clicks constantly when not using the flashers or the blinkers. I replaced the relay and it still clicks. not sure what is causing this.

MAKE 100% SURE BATTERY IS GOOD AND FULLY CHARGED BEFORE BLAME IS LAID.
THEY BLINK CONSTANTLY EVEN KEY OFF?
OR STUCK BLINKING ENDLESSLY KEY ON.?
OR BOTH.>????????
AND WIGGLING THE STALK (BLINK) DOES NOT FIX IT. (Mine failed once (intermittant) and remove it and put it back and runs now or 1 full year, spare in my kit never used. sigh.
NO YOU HEARD WRONG ON RELAY, THE MIP IS SOFTWARE THAT BLINKS BLINKERS.
1995 JEEP IS NOT SAME AS 2008 OR 2010.
SO DO NOT TALK TO OTHERS ON 1995 JEEPS.
OR BELOW 2005 OR ABOVE 2010; OK?
SEE HOW GOOGLING GETS LIES.?
AND SOME OWNERS ARE CLUELESS ABOUT YEARS.
the "module left control" can not be replaced by you
and is not sold new , and most be programmed.
it is dealer only fix. and super expensive over $1000
yes the stalk is easy fix. and PnP plug and play.
why not scan the PCM first see errors. i bet.

cars are complex. I have the full service manual on this car and own one too.
first tell all that works and does not work right, in brief
engine starts?
and runs and drives:?
all other lamps work, brake, park,heads?
left blinker stuck on front and rear and the dash cluster blinking too? (3 lamps to see)>>??????????

USA answer and Car only.'
left lamps only thing failing. answer.

the front located MIP, controller has 2 sub modules
for front L/R and rear L/R
ALL LEFTS FAIL, (STUCK)
or bad stalk.
after removing mine last year, and putting it back it never failed again.

just snaps off after 1 screw.

Most cars the flasher relays are up under the dash not far from the steering column. I had several makes of cars and they all were up there.

There are a few things that can make it look like a bad relay. Most times it's a bulb that has burned-out. Or your blinker unit has gone bad. A Chilton/Haynes repair manual, available at your local auto parts store will tell you where your relays are. But I'd check the first 2 items first. Or check your fuse that controls the turn signals.

Look near the fuse panel and you will see a cylinder (about an inch in circumfrence) this is your blinker relay. Usually there is a seperate one for flashers and one for blinkers. I am not sure that it would make your front flashers illuminate.

Ground wire or connection probably requires renewal.

sounds to me the switch is bad, as if its stuck in the turn signal position, could be the relay or blinker faulty. Replace the blinker/relay and if thats all good, its your turn signal switch.

The flasher relay is probably defective. You need to replace the flasher unit. If that doesn't cure it, you have a wiring problem where the relay is getting a constant signal from the turn signal switch.
First try to unplug the flasher (it would be under the dash-follow the clicking sound) and plug it back in. If no help, replace the flasher.

under the dash is a blinker solenoid. it constantly clicks when the turn signals are on. could be bad. Does the four way hazards work? if they do then it will be your turn signal switch (the handle you use to turn on the turn signals.) I've been a mechanic for 10 yrs. Hope this helps

Try replacing the turn signal flasher first.It should be above the drivers feet near the steering column and looks like a typical flasher unit. A little round canister with 2 wires,sometimes 3 wires.It is what you hear clicking when using the turn signals.

there is a turn signal relay under the dash. about 1 inch high and about the width of a quarter. replace it should be fine. $5 part. happy new year.
