    Removing the old one takes a little thought. I used a large channel lock plier, opned it wide enough to grip the entire body of the old turn module, With my other hand I tapped on the pliers to pop out the module. Took 10 minutes to think of how to do it and 30 seconds to pop it out. New module working fine so far. My old one did not activate my left turn signal every time, sometimes it worked sometimes it didnt. New one working fine.

    5.0 out of 5 stars Genuine AC Delco Part - Fits & Works Just Like It Should
    Reviewed in the United States on September 3, 2019
    Verified Purchase
    Perfect replacement for my customers truck when his trailer lights started malfunctioning.

    Customers 2004 Silverado 2500HD. He thought something was wrong with his trailer when his right turn signal began to flash both the right & left turn signal lights only on his trailer, not the truck.

    I quickly determined that the problem was his truck & not the trailer. Looking at the trucks wiring diagram & a quick check of what was going on in the under dash fuse box, I determined that this flasher unit was bad. I really don't think my customer believed me. I told him if this didn't fix it I would fix it for free.

    Amazon got me the relay the next day & it was far cheaper than the local GM dealer. It only took a few minutes to install & the turn signals are working correctly on the truck as well as the trailer. My customer was impressed. Money in the bank.

    Highly recommended part thank you to Amazon for selling it cheaper than & getting it to me just as fast as the local GM dealer would have. 5 Stars for all.

    First of all let me clarify my 5-Star rating for "Easy to install". It is job that requires a little study on YouTube before attempted. The flasher is not a simple pull and plug. It is a tight fit and without the YouTube help, it would be worrisome to pry and pull so hard to remove the original from the tight space. That said, it fixed my problem.
    My symptom: 2003 Suburban left turn signal would either stop flashing or not flash at all. All other functions were not affected.

    5.0 out of 5 stars This part number seems to be the updated GM part number for 15764135
    Reviewed in the United States on May 20, 2018
    Verified Purchase
    I have been having issues with my Left turn signal not turning on. I could generally turn off and try again and it would start working. Seems like a Relay starting to go bad. The Orignal part# that I pulled out from my 2003 Silverado is 15764153. 2/4-W/Opt. Trailering. This relay is found behind the fuse panel on the left side of the dash.

    The easiest way to get to it is Pull the plastic trim around your gauges. You can do this by lowering the steering wheel as low as it can go and then moving the shift lever down all the way. You'll have to use your key, turn on and then lower. Then carefully pop the trim. It snaps in., so it'll pull off. Just take your time and them slip it out of the way. There is a panel under that, under the wheel. That comes off with 2, 7mm screws on the bottom of each side. Remove the 2 screws. The top is held into place by a pin on each side. You can pull it straight to you. You may have to go at a bit of an angle to get past the parking brake lever. You can now easily see the flasher relay plugged in. There's a bracket kind of in your way, so it's not the easiest to grab onto. I actually used a small screwdriver and was easily able to poke into it, just enough, where I was in it, and then pry against the mount going around it. Once it was out some, I could grab it and pull it the rest of the way out. Pay attention to how it comes out so that you can look at the new one and install it the exact same way. Line it up and push it in. It should go in pretty easily. Then put everything back together in the reverse way.

    Maybe if you have a different truck. If your flasher still works somewhat. You can turn it on, and then look under your dash with a flashlight and see where the clicking sound is coming from. That's the relay working. Then you have to remove what you need to carefully to get to it. It's not that hard.

    The new one is an updated part#. My turn signal is flashing the same speed as before. It's all working good now. If I have an update, I'll post it here.
