How do you locate and test flasher relay on a 2006 Chevy Equinox? Turn signals and hazards stopped working after changing audio system. Fuses test good. Thank you, Mike


Did you change any wiring , tap into any wiring ? There is no flasher relay on your vehicle . It controlled by the BCM !
Turn Signal/Hazard Lamps
The body control module (BCM) is responsible for controlling the turn signals and hazard lamps. When the turn signal switch is placed in either the left turn or right turn position, the BCM receives a signal from the turn signal switch. The BCM then sends an on-off voltage signal to either the left or right turn signals and their instrument panel cluster (IPC) indicator. When the hazard switch is pressed, the BCM receives a signal from the hazard switch. The BCM then will send an on-off voltage signal to all the turn signal lamps. All the turn signal lamps will flash including both IPC turn signal indicators.
Your best bet , take it to a qualified repair ! We on here have no clue what you did . On this newer vehicles ,if you know nothing about automotive electronics you really should take to a professional

The hazard back lights wont quit blinking when car is running even when i pull the fuse on a 2002 buick regal


What fuse are you pulling ?

Hazard Lamps
The hazard warning switch is part of the turn signal switch. The turn signal switch receives battery voltage at all times through the HAZARD SWITCH Fuse. When the hazard switch is placed in the HAZARD position, battery voltage is applied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher sends a turn signal flasher signal to the turn signal switch. The turn signal switch provides all of the turn lamps and turn indicators with the turn signal flasher signal, simultaneously flashing them on and off.

Turn Signal Lamps
The front turn signal lamps are made up of the front park/turn signal lamps and rear turn signal lamps. The front turn signal lamps flash with the rear turn signal lamps when a turn is initiated using the turn signal/multifunction lever. The turn signals will operate only with the ignition switch in the RUN position and will not operate during hazard flasher operation.
When the ignition is turned to the RUN position, battery voltage is supplied to the TURN SIGNAL Fuse. Battery voltage is then applied through the turn signal fuse circuit to the turn signal switch. When the turn signal switch is placed in the LH or RH position, voltage is supplied to the hazard lamp/turn signal lamp flasher. The hazard lamp/turn signal lamp flasher supplies a turn signal flasher signal to the turn signal switch. With the turn signal switch in the LH or RH position the corresponding turn signal indicator, rear turn signal, and front turn signal receive the turn signal switch signal and will flash. The front turn signals receive the turn signal switch signal from the turn signal switch via the BCM. The turn lamps are permanently grounded.

Replace the turn signal switch. Refer to Multifunction, Turn Signal, and Hazard Switch Replacement - On Vehicle in Steering Wheel and Column - Tilt.

The fuse for a right turn signal on a 2001 Buick Park Avenue


The left an right turn signals get there power from same fuse ,HZDT/SG fuse 15amp in the left under hood fuse box. through the turn signal hazard flasher module. Here is how they work .
Turn Signal/Cornering Lamps
The HZDT/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal/hazard flasher module and have ground at G202. The turn signal lamps may only be activated with the ignition switch in the ON or ACCY position. The T/SIG fuse in the fuse block - underhood - left supplies battery positive voltage to the turn signal switch. When the turn signal switch is placed in either the left or right position, current flow is from the turn signal switch assembly to the turn signal/hazard flasher module. The turn signal/hazard flasher module then sends an on-off voltage signal to either the left or right turn signals and their instrument cluster (IPC) indicator. When the hazard switch is pressed, all the turn signal lamps will flash including both IPC turn signal indicators. The left turn signals have ground at G106, G400 and at G402. The right turn signals have ground at G105 and G400. The turn signal switch supplies battery positive voltage to the cornering lamps, the left cornering lamp has ground at G105 and the right cornering lamp has ground at G106.The turn signal switch or the turn / hazard flasher module is bad or there is a wiring problem. Go to you tube an check out a few videos on basic electrical testing ,then get a DVOM - digital volt ohm meter , an wiring diagram an trouble shoot the circuit . There may even be a video on test turn signal circuit .

Where is the emergency flasher relay located on 2013 Rogue?


Here is what the service manual says. Looks like it is not a flasher relay but a function of the body control module.

TURN SIGNAL AND HAZARD WARNING LAMP SYSTEMSystem Description OUTLINE Turn signal lamp and the hazard warning lamp is controlled by combination switch reading function and the flasher control function of BCM.
TURN SIGNAL LAMP OPERATION - BCM detects the combination switch condition by the combination switch reading function. - BCM supplies voltage to the right (left) turn signal lamp circuit when the ignition switch is turned ON and the turn signal switch is in the right (left) position. BCM blinks the turn signal lamp.
HAZARD WARNING LAMP OPERATION BCM supplies voltage to both turn signal lamp circuit when the hazard switch is turned ON. BCM blinks the hazard warning lamp.
TURN SIGNAL INDICATOR LAMP AND TURN SIGNAL SOUND OPERATION - BCM transmits the turn indicator signal to the combination meter with CAN communication while the turn signal lamp and the hazard warning lamp are operating. - Combination meter outputs the turn signal sound with the integrated buzzer while blinking the turn signal indicator lamp according to the turn indicator signal.
HIGH FLASHER OPERATION (FAIL-SAFE) - BCM detects the turn signal lamp circuit status by the terminal current value. - BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal lamp operating. NOTE: The blinking speed is normal while operating the hazard warning lamp.

After using turn signal you can still hear clinking, is hazard relay part of turn signal


The hazard switch is also the device that supplies the turn signal "flash". If you continue to hear the noise of the turn signal flashing when the turn signals off than the problem is the turn signal switch. It is grounding The purple wire from the hazard switch which makes the hazard switch think the turn signal is on. The fix for this is to relace the turn signal/multi-function switch. Typically they will start to go bad in stages. Your symptom is the first stage. Eventually either the turn signals or the brake lights will also sto working. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

My hazard lights won't come on at all. The turn signals work fine, as long as the hazard button is not depressed. The hazards used to work, but if the hazard button was pressed and I put on a turn signal,...


sounds like a dirty switch, happens a lot in the UK as the switch is checked for the safety every year so the dirt in the switch causes open circuits, it is a complicated switch, it has many contacts that do different things when in and out, try a salvage yard
