Gieger counter noise

[teddybear]

Sounds like a gieger counter under drivers side dash. Tick click sound. Sometimes more clicks sometimes less. Does not do more or less no matter what you do. Steering, speed, bumpy road, nice road, moving steering column, turning. Turning off all electronics does nothing. Nothing changes the constant noise except stopping. Or going under 5 mph. Stops sometimes for no apparent reason. Sometimes for days. Sometimes for minutes. Making me crazy. Any ideas? Thanks 2015 Yukon Denali

Some joker put a large zip tie on your drive shaft or front drive axle?

Baseball cards in your spokes?

How loud is the noise?

What if it really is a gieger counter?

Remove radioactive material and re-test


Have you emptied your glovebox to rule out something rattling around in there?

have you pulled off the lower trim cover and tried to locate the source?, maybe pull off the lower cover, put your camera phone on record and while you are driving move the camera around under in various areas and then stop and play it back and see if the you can find the source from the recording playback?

Sound comes from under drivers dash. like down by steering column there abouts.

There's a big power block down there with a bunch a harnesses plugged in. Unplug then one by one and inspect for signs of arcing. Use a little dielectric grease on them and plug them back in firmly.

OR....

how's your HVAC system working? Try hot and cold on all vents and report back.

I will try it.

Haha....feel your pain!!!! My 08 Yukon has done something similar for years. Kept hoping whatever it was would just give-up and then would be able to determine source as I dont feel like going under the dash. Like teddy said, I think mine is HVAC related because I have got it to stop when changing defrost/vent selections, almost sounds like a regulated HVAC pressure valve that is "hunting". Mine also sounds like the noise also comes through the audio system I presume from the chime and warning system maybe.

Fender liner rubbing on tire?

My '12 does it on startup, I'll see if I can grab a video. It almost sounds like lifter tick but its more sporadic, less consistent, and not rpm dependent.

Infamous LS engine lifter tick, mine has it but goes away after 45 seconds.

I had a similar noise in my 02. Turned out to be the mode actuator, which is the super hard one to replace on that model.

Sorry for the potatoe cam, front camera turned on for some reason.

sounds like it is coming from the outside to me

 

[Rocket Man]

That’s hard to hear.

Supply fan motor to hvac has toasted bearings. If installed, clogged cabin air filter or an obstruction in the hvac ductwork or flap gone wild.

It sounds rotational and spinning off axis. Order an automotive stethoscope on the cheap from China Freight.

You are definitely not alone! I have the exact same "Gieger counter" noise coming from under my dash somewhere and its driving me batty!
I had a Jeep Wagoneer that the speedometer cable would make the same noise in the cable housing while it turned...hmmm
