My left rear turn signal does not work while the front left does. I checkedthe bulbs fuses and flasher and they are OK. Where do I go from here?? Thanks Dan

Both front an back signals ? You would need to look at a wiring diagram to see what or if these circuits have anything in common . Probably both of these have a different ground point , looking at a wiring diagram i see the front ground is G100 an the rear is grounded at G302 .
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.
Possably the turn sign/flasher module is going bad .
2. Checked the tail turn signal by swapping passenger and driver bulbs. (bulbs twist out). At least the rear bulbs were OK. The wiring seemed intact, with no water leaks, etc.
3. Tested the circuit by removing flasher relay. Inserted a jumper wire between the 2 and 6 locations (Thanks to the message in this thread). The front, rear and dash turn lights all checked OK.
4. Replaced the relay - Honda part 38300-SDB-A03. $23 bucks at local dealer.
The flasher is under the dash.If you turn on the signal listen for it's location.Turn on your 4 way flasher and see if the left rear light is flashing.If it's not then replace the bulb.If it still does'nt work after replacing the bulb check if there is power to the socket. Use a probe light.If no power to the socket.There is a break in the wire or worse the signal switch may be the culprit
sounds like one of light bulbs was malfunctioning and caused the flasher unit to blink rapidly and iy burned out. Replace front and rear turn lite bulbs and see if flasher flashes. if not check fuse and replace fuse. If fuse okay replace flasher unit. Good luck
If the right flasher is working and the left flasher is not, that should be a burned out light bulb, either front or rear. (outside) If you will wait until it is dark, it is easier to diagnose. After dark, turn on the right turn signal, then look carefully at the brightness of the front and the brightness of the rear turn signal. Now, turn on the left, and again observe the brightness of each. One of the bulbs should be out, or not as bright as the other side. That is the bulb you will need to replace.
When its blinking fast look at both front and rear to verify which bulb isnt flashing. If the right works OK, then the flasher is OK. The flasher is INSIDE the front control module/integrated power module. If you cant find the problem, you may need a dealer to check it.
Check and make sure both front and rear left turn signal bulb light up, if they do, replace the turn signal flasher, flasher sit under dash in fuse box, if one or both bulb don't light up, replace bulb.
If the fuses are good and the front and rear bulbs are good, change the flasher for the turn signals, even tho the right is working. If that doesn't fix the problem, it might be in the turn sgnal switch on the steering column.
If both bulbs are good for the backup lights and fuses are good, then the backup light switch, which is screwed into the side of the transmission has to bad.
