Turn Signal Flasher

Do you know what a DVOM - digital volt ohmmeter is ? How to use wiring diagrams to test electrical circuits with DVOM? Do you know how the turn signals work ? What controls them ? More then likely it's a problem with turn/hazard flasher module.

Turn Signal/Hazard Lamps
The IGN E 10 A fuse in the underhood fuse block supplies battery positive voltage to the turn signal switch assembly. Ground for the hazard switch is from G302. The FLASHER 15 A fuse in the underhood fuse block supplies battery positive voltage to the turn/hazard flasher module. 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/hazard flasher module. When the hazard flasher switch is activated, a ground signal is completed from the hazard switch to the turn/hazard flasher module. The turn/hazard flasher module then sends an on-off voltage signal to the appropriate turn signal lamps, or to all turn signal lamps for hazard operation through these fuses:

Do the hazard light's work ? Did you try replacing the turn/ hazard flasher ?
Remove the LH instrument panel (IP) insulator. Refer to Instrument Panel Insulator Replacement in Instrument Panel, Gauges and Console.
Remove the steering column filler panel. Refer to Steering Column Opening Filler Replacement in Instrument Panel, Gauges and Console.
Grasp the hazard and turn signal flasher and slide the flasher to the right to release the flasher tabs from the slots on the BCM bracket.
Disconnect the electrical connector from the hazard and turn signal flasher.

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.

try the hazard lights. if they work check the bulbs with them working. if good and the turn signals not working then it could be the signal flasher is bad. witch out the hazard flasher for the signal flasher it they work then replace flasher, or the turn signal switch it bad.

There should be a turn signal flasher and a hazard flasher. They are two different parts. If you replaced the hazard flasher and not the turn signal flasher than I would start by replacing the turn signal flasher.

One thing you can do once you find the turn signal flasher is to unplug it and use a jumper wire between the two pins of the connector then turn the key to the run position and place the turn signal lever in the left or right position. If the turn signal lights know light up than the turn signal flasher is the problem

you don`t say but do the lights work either on the front/back on both sides.if not then it may be a fuse that needs replacing or need a bulb replacement.if the lights work but don`t flash then it sounds like a signal flasher problem.the flasher is located in the fuse panel under the dash on the drivers side.if the hazard flashers work then turn them on to find the hazard flasher by the fuse panel then you will know what the signal flasher looks like and change the signal flasher.make sure you change the one for the signals and not the hazard one.if the hazards work then i would say the signal switch is good as the hazards work through the same switch.

you have a separate flasher for the turn signals.this is what your problem sounds like.if all your lights are working including the signal indicator on the dash then it will be the signal flasher.if you turn on the hazard flashers and locate it under the dash, this will show you what the turn signal flasher will look like.then you will have to look for the flasher unit on the fuse panel that looks like the hazard flasher.replace the turn signal flasher and you will have your signal flashers again

The turn signal flasher relay may have a problem.Turn on the hazards and follow the clicking sound to the source and usually the hazard flasher and turn signal flasher are very close to each other.Remove the one that is clicking and put it in place of the turn signal flasher.If the Turn signals then work you will need to purchase a new turn signal flasher relay.They are usually just a few dollars.

You changed the hazard flasher or the turn signal flasher? It has two, one for the hazard and one for the turn signals

Try your hazard lights. If they work, then it's your turn signal flasher. With your hazards on, listen under the dash for the constant "clicking". Locate the flasher for your hazrads... the turn signal flasher should be near it. Once you find it, just pull it out and replace.

You can use your hazard flasher in place of your turn signal flasher, just swap the two. This will get you to the store to buy a replacement.
