Unknown Dash Console Cab Noise - 2002

2002 Silverado 4X4 Regular Cab Z71 5.3

WHAT is this squeaking noise? Anyone?

Truck has a minor soft low pitch sometimes intermittent muted squeaking noise coming from somewhere near the ash tray area - or near the airbag key/light on dash - or someplace nearby.

Yes, have removed ash tray - that's not it.

Could be coming from heater area.

Noise does not fluctuate with heater fan. Heater fan Off. Still noise. Heater fan on any speed - noise is the exactly the same. No change is pitch or sound on any fan speed.

Turn the engine off - then key in ON position - still squeaking noise.

Hvac? I have a ticking or popping noise that I'm trying to figure out under my dash. ticks and pops weather the fan is on or off. Only does it when i mess with the climate levers heat or cold.

I have a 2002 myself and have been doing a lot of work to it recently. any chance the sound disapears when the guage/radio trim/bezel is off?

I found it most interesting that GM put a micro bead of rtv like substance around the inside edges of the bezel to eliminate squeaking and vibrations. I wonder if that's deteriorated or fallen off on your car and is the cause of a squeak that you hear.

Thank you for the answers. Note that the sound is sporadic.

Sometimes no issues. No squeaking.

Sometimes the sound all day or squeak one trip.

Well. It's been a month now.

And no squeak.

Sounds like your noise may be the blend door actuator.

I chased a squeaking sound for more than 10 years on my 2002, that I though was coming from behind the gauges in the dash. I ripped that thing apart stuffing foam and felt everywhere. It turned out to be excessive slop in the lower steering column bearing. Added a worm drive clamp for $.90 and fixed it, per the link below.

Had noise on and off for about 4 months. Last year.

So far, it's been gone for about 6 months.

Well, that dash sound was weird.

I did take truck to local mechanic and he heard the noise. As if continued I was going to have this looked at further. It was a muted sqeaky noise.

It was there for weeks at a time. Then would go away. Then come back. Seemed to come from just above the ash try or thereabout. It did not sound like anything coming from the heater/fan. But who knows.

It is gone now for quite awhile.
