Turn signal bulb replacement - 2006 Pontiac Montana SV6

If the front and rear bulbs flash fast also, replace the hazard switch or you could live with it. As they are working. If one doesn't work, check grounds. I just run a new ground, much easier than cutting open the harness to find the break.

was the correct bulb used? this sounds like a single function bulb was used NOT the bulb that will light with the headlights and ALso produce turn singles

ck turn signal switch.

RIGHT BULB SOCKETS SOCKETS COULD BE CORRODDED,SPRAY A LITTLE ELECTRICAL OR ELECTRONIC CLEANER CLEAN BULBS SOCKETS.MAKE SURE YOU ARE USING THE RIGHT SIGNAL BULBS TURN SIGNAL BULBS HAS TWO FILMENTS.IF ALL IS GOOD TURN SIGNAL SWITCH COULD BE FAULTY.

Your turn signal bulb is a 1157A or 1156 bulb (either will work), and usually inserts into a connector
that unscrews 1/4 turn counterclockwise, and comes out of a headlight-turn signal assembly on the
front of the vehicle.
Try: opening the hood and turning the bulb holder 1/4 turn counterclockwise, then withdraw the
bulb base and installed bulb. replace old bulb by turning it 1/4 turn counterclockwise and
pulling it out (the 1157A and 1156 bulbs are bayonet-base). Install the new bulb by inserting
into the socket (properly aligning the 2 pins on the base of the bulb with the channels for them
in the socket), and the rotating the bulb 1/4 turn once inserted.
Now - test the new turn signal bulb before putting it back together - this insures that the installation
of the bulb into the socket correctly aligned the (2) contacts in the base of the bulb socket.
Then: insert socket into headlight-turn signal assembly and rotate clockwise 1/4-turn to install.

Summary: remove socket by rotating 1/4-turn counterclockwise and pulling out.
remove 1157A or 1156 bulb from socket by rotating bulb 1/4-turn counterclockwise and
pulling it out
installation is reverse of removal.

check the front and rear turn signal and brake bulbs ,check for filament wear or drakness in bulb glass.if this is found replace bulb,you may also have a bad ground to a bulb socket, turn lights on (signal and break) and wiggle wires at bulb socket, watch light, if it dim any replace that socket and check the ground wire.

Replace the bulb(s). Tail light bulbs have more than one filament. One is for the brakes and one is for the turn signals. The reverse light is a light all by itself. When the filament for the turn signal goes out the brakes will still all light up, but the turn signal will not.

YOU HAVE TO THE FRONT HEADLIGHT HOUSING TO REPLACE THE TURN SIGNAL BULB.

probably need headlight bulb too, check fuses first.

you may be able to access the bulb housing under the hood. open the hood and look behind the turn signal for the bulb housing. once located, grasp the housing and turn counterclockwise about a quarter and then pull. be sure to replace wtih the same type/part number bulb.
