The Left & right signals have stopped working-they do not flash-no indicator light shows on dash board. Have checked all fuses and the flasher.

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.

Turn signal switch is probably the problem ,but without testing that is just a guess. Do know i replaced a few on grand am's . What relay ???? There is no relay in the fuse box for the turn signals . Your vehicle has turn / hazard flasher module .
Turn Signal Lamps
The TURN-B/U fuse and the STOP/HAZ fuse in the IP fuse block, supplies battery positive voltage to the flasher module. The turn signal lamps may only be activated with the ignition switch in the ON position. When the turn signal switch is placed in either the left or right position, current flow is from the flasher module's output to the turn signal switch assembly. The flasher module 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, all the turn signal lamps will flash including both IPC turn signal indicators.
Located under the driver side of the dash above the brake pedal ,on a metal bracket .
Turn Signal/Hazard Flasher Module
On the dash harness near the steering column

emergency flasher & turn signal flashers are separate.

ck fuse for rear taillights tis under the dash lower left of steering wheel. or if you still have the manual look in there under fuses.
also look for a bad ground but i doubt that.. if it's both rear out.
fast flashing well here's a chart with all sorts of info.
Problem What To Do Turn signals light, but do not flash Replace the flasher No turn signals light on either side Check the fuse. Replace if defective.
Check the flasher by substitution.
Check for open circuit, short circuit or poor ground. Both turn signals on one side don't work Check for bad bulbs.
Check for bad ground In both housings. One turn signal light on one side doesn't work Check and/or replace bulb.
Check for corrosion in socket. Clean contacts.
Check for poor ground at socket. Turn signal flashes too fast or too slow Check any bulb on the side flashing too fast. A heavy-duty bulb is probably installed In place of a regular bulb
Check the bulb flashing too slow. A standard bulb was probably installed in place of a heavy-duty bulb
Check for loose connections or corrosion at the bulb socket Indicator lights don't work in either direction Check If the turn signals are working
Check the dash indicator lights
Check the flasher by substitution One Indicator light doesn't light On systems with 1 dash indicator:
- See if the lights work on the same side. Often the filaments have been reversed In systems combining stoplights with taillights and turn signals
- Check the flasher by substitution On systems with 2 Indicators:
- Check the bulbs on the same side
- Check the indicator light bulb
- Check the flasher by substitution
hope this helps. may want to print for future reference. :)
hope this helps.

Check fuse # 12 and 14 at the power distribution center (fuse box) in the engine compartment near the battery. If both fuses test good, the the more likely cause of your problem is either the turn signal / hazard switch or the Combination Flasher / Daytime Running Light module. This module is located on the junction block, behind the left side of the dash.

The switch can be tested by accessing the wires at the base of the steering column.
Left turn signal = Light Blue / White
Right turn signal = Light Blue / Yellow
Hazard flasher = Dark Blue / Pink

These wire should show ground when the switch is actuated in its respective positions. If ground is not present when the switch is actuated, check also the black wire at the switch. This wire should show ground at all times. If you do not get ground on this wire than there is an open in this wire. Repair or re-grounding this wire should solve your problem. If the switch test good than the Combo Flasher / DRL module will need to be replaced.

most likely its your muti-funtion switch in the steering column.but first check your turn signal flasher & your emergency flasher

Change the flasher which is located up by fuse block under dash

If the turn signal indicators all fail at once, it's most likely the flasher needs to be replaced. I'm not sure of the exact location on your accord, but check under the hood at the fuse and relay panel (some hondas are located there) or under the dash, driver side fuse panel.

flasher relay is corect

Hello I had the same problem on my 04 monte. After changing bulbs ,checking wires etc. I finally took it to the dealer and they found out it was the hazard switch. After swapping it with a new one all lights, dash etc started working again and have not had another problem
