Chevrolet Suburban Noises and Sounds
I have a 1999 suburban and in the last two days I constantly hear the clicking of my blinkers even when they are not on. The clicking will stop when the brakes are applied. Is this the relay about to go out or is this some type of short? Thanks for your help in advance.
This discussion has been closed.
Start first with having someone just apply the brakes, and notice whether all of the brake lights come on correctly (and are of equal high brightness), as well as center stop lights.
Now have someone turn on the left turn signals, and observe both the back and the front turn bulbs. Now do it with the brakes applied and observe whether the bulbs are acting correctly. Do the same procedure with the right turn signals.
Now turn on the parking lights (you may want to do this at dusk), are all the parking lights on correctly front and back? Now do the whole right/left turn signal sequence with braking tested as well.
I'm suspecting you will see some unexpected blinking at one or more of your lights.
Let us know which of these yield some results that are unexpected.
When it is clicking, is there an inside indicator light blinking?
When it is clicking and you then turn on the turn signal, does the clicking change?
Have you recently added a trailer hitch/wiring to this vehicle....or changed any of the bulbs in this vehicle?
What trim level is this suburban? LS/LT/LTZ
And have you wiggled (or turned on and then off), your 4 way blinker switch.
And does this clicking occur without the key in? In the accessories key position? or in the engine ON position?
When the clicking is happening nothing is happening outside of the vehicle
during the clicking the inside indicators are not working either
when I turn on the turn signal it is in sequence with the constant clicking
No bulb changes and no new wiring
I haven't tried the 4 way yet but I will
It happens in the accessory position and in the ON position.
You don't 'appear' to have a typical bulb filament problem, as you indicate you are seeing the correct intensities of the bulbs flashing....and everything externally is working absolutely correctly. The only thing that I would probably do to prove it if wasn't a bulb problem (because your problem might be much more expensive), is to actually remove all of the exterior bulbs and see whether you still had the clicking. If the clicking goes away, then you really do have a bulb problem and can start putting them back one by one until you find the culprit which caused the problem.
In my 2007 Suburban, by looking at the service manual schematics this turn signal circuitry is actually controlled by a computer called the Body Control Module, which sits up underneath the dash by the steering column. What I don't know is whether you have this BCM in your model or not. In my previous generation Suburban, the flasher is a solid state plugin flasher. So I'm not sure which type you have. If you have lights (like dome lights and exterior courtesy lights) which brighten up slowly and dim down slowly, then you probably have a BCM.
If can find a solid state plugin flasher, then that would be the next most likely possible culprit (besides the bulbs). If you can't find a plugin flasher, then I think you are looking at replacing the BCM.
Perhaps someone else who may have actually had your problem can jump in with the resolution.
Any ideas on what can I do? THANKS!
When the car is turned on after being off and I go to 8-9 mph there is a "Pffft" sound in the driver's side door. It only does it the one time after being shut off and does not do it during any stop and go or regular driving. Only after the engine has been shut off and then you drive it does it make the sound.
It's been at the dealer since Monday and I just got a call today saying that believe it or not this is a normal noise for the Suburban. Don't know whether or not to believe them. Is this a normal noise?
Only one time when the car is started and you get to 8-9 mph then there's a "Pffft". That's it. Can drive for hours in stop and go traffic and it won't do it again - until I turn off the car (i.e. - parked to run into a store etc). When I get back into the car and start it - it will do it the one time at 8-9 mph.
According to GM (says so on the paperwork ;-) this is a normal noise.

That post explained about a this noise coming from the shock absorber and it has to do with some bushing or something like that. That post explained how GM has a TSB on it and how to replace these bushings.
The problem might have started because your shocks probably extended all the way when they lift your car up for changing your tires, i.e. the shock probably moved to its end and caused this noise to appear due to that faulty bushing (or what ever it was).
Wal-Mart guys have nothing to do with this.
Now, regarding that TSB, one thing I did do last night was to log onto mygmlink.com website and search for recalls/TSB. Entered my VIN and nothing was noted for it. I suppose with a TSB they don't publish it, just address it if you have a complaint? And I presume it is not affected by in/out of warranty status? I would like to look up and read that TSB, but I don't suppose they'd do anything at a dealership unless they could re-create the symptom? And I don't want to get stuck with a diagnostic fee and be told everything is fine.
Any ideas as to what was going on what to do about it?
Right bulb would work fine.
Left bulb, when you put on the turn signal, would energize both the left turn filament , and the circuit for both bulbs running lights. Would appear to you the both sides are blinking.....although the right bulb would be blinking 'dimmer' than the left.
So sounds like it's the Air Pump for the Auto leveling suspension?...it just keeps running, and will not shut off. I had to disconnect the battery to shut it off.
Is there something to do to shut it off temporarily (like a fuse?) or does this item need to be replaced?
Thanks for any assistance.
It turns out to be the ABS module.
thanks for responding.
