Question about 2007 GMC Yukon XL Denali

1 Answer

The sound in the car completely stopped working in the middle of a movie...not even the blinker/turn signal makes a sound. What could have caused this, how do we fix it? We've checked the fuses and nothing is out. The rear seat audio panel also isn't working, so I'm wondering if they're connected??

I had this problem several months ago, but for some reason it started working again on its own. Haven't had the issue since (btw, this is on an '08 Yukon Denali XL). No sound, blinkers were silent, the headlights on warning when the key was out and driver's door opened didn't work. I did learn that the blinker clicking is generated in the audio system. It used to be a relay that clicked. Check for pinched wire harness below and around the drivers seat.

BLINKER


The emergency flasher in the center of your dash is a module. it is causing this problem. call your local GM dealerand givethem your VIN# because some of these were replaced for no charge to the customer. VIN# is on a steel plate mounted to the top of your dash. it can be seen thru the driverside corner of your windshield,from out side the car. This is called a flasher module, and it will stop your tail lamps from working also.It is veryimportant to do this as soon as posible.

that vehicle has a desperate relay for the hazards which is why they work, you have a defective signal flasher sometimes called a signal relay, follow the noise to locate exactly where the part is, usually under driver side of dash, it is a very cheap part and easy to install.

This is most likely going to be an issue with a relay. The relay on the fords that is tied into the blinker module can go bad is it gets wet or over loaded. Are there any after market things added to your vehichle? This can also be caused by overloading part of your ECU if you have after market headlights, or headlights that carry too high a load. When it blinks for 3-4 times and stops, does it blink faster than normal? This can be a sign of a false connection to the light itself. Such as having the wrong bulb in for the blinker.

Turning signals not working all the time


Sounds like the blinker relay. Is the emergency flasher switch on the dash above the radio ? If it is the blinkers relay is the same as the emergency relay. If the blinkers stop working pound on the emergency lights switch and if they start working then replace the emergency lights relay switch cause the blinkers is on the same relay as the emergency lights. My 2001 Grand Am does the same and I just hit the emergency lights switch and they start working again.

Blinking sound that want stop


The simple solution could be the turn signal flasher (which are generally located under the dashboard). Very inexpensive. But you say that smoke was coming out of the turn signal arm. In that case it could be shorted out. To replace the turn signal arm assembly is pretty expensive. Maybe around $200.00 for parts and labor at a shop. Good Luck!

Beeping Noise/Blinker Noise


sounds like your electronic flasher unit maybe stuck causing the noise. they are generally located under the dash on driver side just below the instrument cluster.
