Where is the turn signal flasher and brake light module
Recently had a small front end accident. had body work and light bezel repaired but the brake lights don't work, the emergency flashers don't work and neither turn signal works. Lamps are good, but can't locate "module". The relay under the hood works and the fuses are all good. ???

Doesn't have a flasher , turned on an off by BCM - body control module . Your best bet take it to the dealer or someother qualified repair shop . You should not try anything .
Unfortunately Nissan in it's infinite wisdom decided that it should tie the turn signal flasher and hazard flasher which are useally combined but on an independant circuitwhich only made the front and rear turn signal lights flash as well as the indicator lights in your dash telling you which direction you had selected. They were in no way related to any other circuits, have incorporated these into the body control module. Consequently if you don't have a flasher, you have to buy a body control module. First try operating the hazard flasher mode. It will work even if there ar some bulbs blown. If you have one blown bulb a flasher may operate slower on that side or not at all depending on it's design. Try the other direction if it doesn't work in that direction either, it's probably the flasher or in this case body control module.
Has the car been in a fender bender ? check for wiring going to the front and rear lights to see if on has rubbed into a ground wire or the body. ( even if there has been no accident.)
Yes, it does have a flasher, although it may be a combined unit with the hazard flashers relay. So you hear the clicking of the flasher relay? That seems to indicate the relay is working properly. Have you checked the bulbs and the turn signal fuse? Any turn signal bulbs light up anywhere, front or back?
How about your brake lights, do they work? Your car may have separate, stand alone turn signals in the rear, but many American cars use the same bulb and same filament on the bulb for the brake lights and turn signals. If your merc is like this and the brake lights work, then the bulb must be good. Turn on the hazard flashers and see if all bulbs work and flash at each corner of the car. This would be the same bulb as for the turn signals. If they work, it could be a bad turn signal switch, may even be the flasher relay somehow malfunctioning, and in a few cases, a bad hazard switch can affect the turn signal switch. Check fuses and bulbs first. If you have any type of body control module that controls lights and other accessories, you may have to investigate that. I know I'm not being very helpful, just throwing out a few suggestions. Good luck.
on an older car this woul dsimply mean that the turn signal flasher was burned out for that side. today its more complex. the turn signal flasher is a series of resistors and timer modules located in the workings of the body control module. This can be a simple problem with a shorted line, or a faultly turn switch or something as complex as needing a new body control module. This is something that needs to be repaired by a quality automotive mechnican with an electrical backround, and unfortunatley unless your in the nyc area i have none to suggest to you.
TURN SIGNALS WILL FEED BACK THROUGH THE TURN SIGNAL SWITCH.THEY ARE INDEPENDENT OUT SIDE ON THE CAR BUT NOT IN THE SIGNAL SWITCH.REPLACE THE SIGNAL SWITCH
If I understand you right based on your post/description, the signal lights would still turn on even if any or both of the flasher relays are removed. Should this be the case, then the signal lights are not getting the power from the flasher relays but from the brake light circuit.
Perhaps your concern is not with any of the flasher, but simply missing or loose ground more particularly with the rear lights. Perhaps you could try determining which of the wires for the brake lights and signal lights (as they come out of the light assembly) would be ground . A test and even possibly a temporary workaround is to hard wire a second ground connection from the determined ground wire of the lights and attach it to any conveniently located bolt or screw to the body. it may be to your advantage to do this on all the rear lights assembly.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards. Thank you for using FixYa.
