Blinkers not making a clicking sound?

Welcome to 2CarPros. The click on that vehicle is actually a sound played through the speakers. Do the key in ignition and seat belt warnings still sound? How about the turn indicators in the dash?

That's strange. Did this have a click before or did you just get it and noticed no click?

I haven't been near an Uplander in a while so don't remember if they clicked or not. The system doesn't use a mechanical flasher, the body control module does all the work. That sends a data signal to the dash or radio for the other chimes as well so those are working = the data line is okay. I don't know of any other mechanical item to click and the wiring shows nothing as well.

Hmm The only item about them I find is the turn signal reminder.

Turn Signal Reminder

A chime or audio warning activates as a turn signal on warning if the turn signal remains ON for a specific distance traveled. The turn signal warning sounds when a turn signal remains active, and the vehicle has traveled a distance of 1.2 km (0.75 mi).

The driver information center (DIC) turns the turn signal reminder OFF when the ignition switch or turn signal switch is turned to the OFF position.

There is no internal diagram of the BCM showing what it uses to flash the lamps but it could be a relay. If that is the case the two options would be to open the BCM, find the relay and replace it or replace the BCM, which is close to $200.00 when you add the module and programming it together. Not sure I'd want to do that for a click.

You are welcome. Wish they published the internal schematic for the modules. Could make things like this a lot easier.

Thanks for the information. I've seen a few Chevy Uplanders over the years and never paid attention to the signals other than if they flashed during testing.

Is it still clicking with the signal on? If so can you tell if it's from the speaker and in time with the lights flash rate. It's possible it is something else so confirming it is with the signals only would be the first place to start.

HMM, not sure what would have caused it to come and go like that without it acting that way now it would be hard to test because there isn't a way to hear it. The BCM does the switching and sends a signal to the DIC in the dash that signal tells it to turn on the left or right dash indicator and generate the tone for the operator. The dash is powered on the same fuse that powers the chime. Do the other warning chimes work like key in, seatbelt and such? If not then it could be the chime driver itself but the only way to repair those parts would be to have an electronics repair shop go through the cluster to repair or replace the chip.

That is the issue with some of the things the automakers do on vehicles. It's like many newer vehicles where they have gone from individual components like relays for systems and instead made it a part of the fuse box internals. Now instead of having a high beam relay that can be replaced for $4.00 you have to replace the entire fuse box for $700.00
Or in this case they didn't use a mechanical flasher or even a relay and instead went solid state and made the sound through the radio. If the other chimes work then the data bus is okay and the only fault is no tick, is it worth $200.00 plus taking the dash apart and shipping it out for the rebuild? That is the question the owner has to answer. I know for me I wouldn't bother. It fits in with some of the other noises that automakers are adding into their vehicles. Like the cars that have "engine sounds" that play through the stereo because the real engine sounds like a squirrel in a cage or the new electric Mustang that is quiet but they have added sounds to make it sound like a Mustang!

You are welcome. Thank you for using 2CarPros.
