Brake light and turn signal will not work on a 2005 pontiac g6- replaced the bulbs, are there fuses or something else?

The tail light is usually a bulb with lower wattage, so it won't glow as brightly as the brake and turn lights.. There should be one or two other bulbs in either of the two tail assy's. The turn signal can use the same bulb as the brake light. If so, it's up to the flasher assy to direct the lights to both come on, and/or for one to flash if the brake and turn signal is on, e.g.. There could also be a backup light.

So if the brake and turn lights don't operate, look to the fuses, and flasher assy. for possible replacement.

yes check all the bulbs and the fog lights one blown bulb could knock it all out kinda like in a Christmas tree one bulb goes out the whole line goes out

IF you have no conventional flasher unit the flashing action is done electronically and does not require the current draw to make it work as the flashing is done by a transistor turning on and off . With the led lights I think that there would be less stress on the electronics . Read the fitment instructions for the led carefully and it will be explained if you need additional items to make it all work

real interesting... there should be no relation to the "drive" and the head light. current drawn by the starter causes the lights to go out or dim. Check the headlamp relay and for corrosion on connector to lamp assemblies in the engine compartment. On back of assemblies there is a large diameter plastic retainer after you remove the wire clip. Turn counter clockwise and pull back. a wire clip should retain the bulb itself

Did you check to see if the bulb is burnt out?

you need new bulb thats about all that will cause this problem

fast flashing on the one bulb is a fault is due to the failure of one bulb, hence the holder for the flasher unit not wirking has gone defective the contact may have broke in the flasher unit not working , look in where the bulb goes and compare the working and non working unit, you may see a contact missing, hence repace unit, or repair

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.

Its not the dash light out is it?All did you try using the 4 way flashers,do you hear in clicking.If the 4 ways work,this is turn signal switch bad.

yes your relays are bad or afuse link
