How to get to bulbs behind instrument panel assembly.(All blinkers and lights work fine on the outside lenses of the car) Right turn signal arrow is not illuminating or flashing during a right turn. Need to replace bulb in instument panel to pass NC state inspection.

CHECK TAIL LIGHT BULBS.IF BULBS CHECK OUT GOOD PROBLEM COULD BE CORRODED BULB SOCKETS OR BROKEN LOOSE WIRE IN CIRCUIT.

The turn signal switch is bad,replace it to repair the problem.

What you speak of as to the left blinker doesn't flash, yet the instrument cluster shows the green arrow (to the left), and yet that and the left turn signal lights do not flash, appears to be a simple burned out bulb. If one of your left turn signal bulbs are burnt out, then the #552 Flasher Unit in your fuse box is NOT the cause. It's the "Amperage" not being correct to the flasher unit. Place the parking brake on and start your vehicle. Put the left turn signal on and check to see ALL the bulbs are illuminated for the left turn signal. If you find one bulb that is not illuminated, then replace the bulb. It should be an 1157 bulb, but in the front it could be a 1157 Amber bulb dependent on whether your turn signal lens is clear or yellow.

If you still have difficulty finding the dead bulb, turn on the right turn signal and see which bulbs are illuminated and this will give you an idea as to which bulb on the left side isn't working, or turn on your Emergency Flashers which will turn on both the left and right side lamps and see which bulb is not lit up.

I hope this Helps,

odd speed blinker is a message to tell you that a light bulb has burned or is disconnected. All front lights can be replaced from the engine compartment EXCEPT the turn signal :( .Unfortunately you will have to pull the headlight assembly out in order to reach the turn signal bulb. If the light was off since the assembly was replaced, there is a chance that the socket was simply left unplugged.

It sounds like a bad light socket. The brake light and the parking/running/regular part of the socket are shorting out. When you press on the brake petal it's shorting out on the turn signal and sending current to the indicator (arrow) on the dash.. When you use the blinker, it's shorting with the brake light and causing them both to flash...

Check the socket and get back to me with the result.

I have this exact same issue with my 05 Colorado and its so annyoying (not to mention unsafe)... I thought it was just the blub- becuase in my case my signal is no loger blinking. My break light still works, as does my parking light...

Any thoughts as to why this is happening?

Please HELP!!!

Defintely sounds like the turn signal switch is bad.
If the flasher was bad, your right blinker wouldn't work.

It is posible both bulbs are blown, I have overlooked this before, if not you will have to change the turn-signal switch (in the stering colume.

Your front turn signal socket is shot. Buy a new one at the dealer for about 30.00. It will fix it. You may be able to clean it and wiggle it to get it to work. But it wont last very long. I had the same problem. Replaced the socket and it is fine. Note: If one side is bad the other side it not far behind. Probably 2 or 3 months it will go also. Good Luck.

sounds like a bad ground through one of your lights, the right front or rear turn signal bulb.
