Flashing left front turn signal

[Michaelb1263]

My 2018 Silverado 3500 LTZ is at the dealer for maintenance and a recall issue. Everything is finished except now the left front turn signal is blinking and they don't know why. I can't get it back until they figure it out and fix it. This has not happened before and my list didn't include any issues with the turn signals.

Sounds like someone either started the process of registering the tire pressure sensors on your vehicle or on one close to yours. Have them complete that process on yours.

Unless it’s different on the HDs, when GM vehicles are in the tire pressure sensor relearn mode, the turn signal showing which sensor to recalibrate will stay on steady. I’ve done this for several GM vehicles and they’ve all had steady lights.

Thanks for the reply and the information. Apparently, when they were working on it some wire got shorted out. They disconnected the battery again and when it was hooked back up all was good.

When I changed the lights to led on my Peterbilt I had the same issue. I found out that I needed to change the flasher to an led flasher too. Once I did that the turn signals were fine. I have no information regarding the load equalizers.
