Turn signal & hazard light switch

You probably need a turn signal / hazard flasher module located in the under hood fuse box. These go out all the time .
Turn Signal/Hazard Lamps
The IGN E 10-amp fuse in the underhood fuse block supplies battery positive voltage to the turn signal/hazard switch assembly. The FLASH 25-amp fuse in the instrument panel (I/P) fuse block supplies battery positive voltage to the turn signal/flasher module and ground is supplied at G200. When the turn signal switch is placed in either the LEFT or RIGHT position, a voltage signal is completed from the turn signal switch to the turn sign/flasher module. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the turn sign/flasher module. The turn sign/flasher module then sends an on-off voltage signal through the LT TRLR, RT TRLR, LT TURN or RT TURN 10-amp fuses in the I/P fuse block to the appropriate turn signal or to all 4 fuses for hazard operation. The instrument panel cluster (IPC) indicators receive voltage from the LT TURN and RT TURN fuses as well as the driver door module (DDM)/passenger door module (PDM) for the mirror turn signals. The DDM/PDM has no function or control of the mirror turn signals other that a pass through connection for the circuits. The audio chime is also activated when the turn signals are ON. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators. The front turn signals are grounded at G100. The rear turn signals are grounded at G401. The Mirror turn signals are grounded by the DDM/PDM.

What is a hazard switch and where is it located?
The hazard switch allows you to turn on your hazard or emergency flasher lights. When you press the button, all four of your turn signal lights will flash simultaneously. This is a useful way to warn other drivers of potential hazards or to make your vehicle visible during a breakdown, especially at night, and is an important safety feature of any vehicle.

The hazard switch is frequently mounted on the dashboard. Sometimes it is mounted to the steering column or attached to the turn signal switch. The button is marked with one triangle inside another triangle. This part is also commonly referred to as a hazard or emergency flasher switch, hazard or emergency light switch, hazard warning switch, or simply just a flasher switch.

Your vehicle doesn't use a flasher for the turn signals . Controlled by the BCM - body control module . electronic module ,computer etc...... Did you try replacing the bulb that's not working at all . The one flashing fast could becaused from bad bulb on the other side. So you can take the part back an get your money back . Your best bet , take it to a qualified repair shop.

Turn Signal/Hazard Lamps
When the turn signal switch is placed in either the left or right position, a ground signal is completed from the turn signal switch to the BCM. When the hazard flasher switch is activated, a ground signal is completed from the turn signal/hazard switch to the BCM. The BCM then sends an ON-OFF voltage signal through the fuses to the appropriate turn signal and side repeater (export only) lamps or to all of the turn signal fuses for hazard operation. The driver door switch and passenger door switch also receive voltage from the BCM turn signal supply voltage circuits for the mirror turn signals. The door switches have no function or control of the mirror turn signals other than a pass through connection for the circuits. The audio chime is also activated when the turn signals are ON. The instrument panel cluster (IPC) receives the signals to activate the turn signal indicators over the GMLAN serial data system. When the hazard switch is pressed, all turn signal lamps will flash including both IPC turn indicators.
On certain export vehicles, the auxiliary body control module (XBCM) controls and supplies voltage for all of the trailer lighting functions.
Also my plate light isn't working. Could also be bad bulb's .

Do the indicator lights on dash come on and stay on? If so replace turn signal flasher relay, if not may need a turn signal switch

The turn signal / hazard flasher module is the problem ,more then likely . Without testing this is just a guess . Do you know how to do automotive electrical circuit testing using a wiring diagram an a DVOM - digital volt ohm meter . Plus factory service repair manual flow charts .

i beileve there is a seprit flasher for hazard take to look at that or check hazard switch its maybe the problem.

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

Can you just check to make sure the ignition key switch is not staying over to far and not backing off when you try to start it. I had a truck that did that and it messed up my turn signals until I brought the key switch back a little after starting it. Just a simple idea. Be kind with your rating for me. Raz

This is not fuse, is an flasher, and maybe is integrated with hazard & turn signal module.

Also need review this RECALL

Hope helped with this. Good luck.

Your turn signals and hazards operate on the same circuit...... thats why you lost turn signals when you snipped the wires behind the hazard switch...

your hazard switch is faulty, stuck in an open loop (always on).......replace it

ebay is best, if not then Autohaus AZ
