Tahoe Random Chirp Under Dash While Driving

[ScaryDonuts]

Unplug it or remove the fuse that powers that box. If the noise stops that's where the chirp is coming from.

I’ve had it unplugged for a couple of days now and the car still chirps. This is the only aftermarket item on this car so I believe it must be a chirp for something malfunctioning or maybe a ground wire making something mess up.

The chirp definitely happens in relation to me pressing on the brakes sometimes so maybe it’s the brake booster messing up?

Let me know your guys ideas!

Spray wd40 on the brake pedal joints.

Brake pedal squeaking

No difference in the feel, but the brake pedal is squeaking when I step on it. It doesn't make any noise on the release. Seems to be acting up more in the cold weather. Very annoying. Any ideas on how to shut it up?

A month later and sadly the WD40 did not fix this sound

[Update] I put new front shocks in the Tahoe because they were leaking and in my mind I was hoping this would help fix this chirp issue because maybe there is an alert system that tells you when your shocks are going bad but nope.

I found a forum with multiple people explaining the exact problem my car has maybe this forum will help someone solve this mystery?

General Tech - Random chirping - I have a 2005 Suburban. I hear a chirping sound (like the alarm chirp) at random times while driving. It it intermittent and random. It sounds like it is coming from in the dash. Sometimes while I turn the car off it chirps slightly 3 times. The last episode was...

I’m just trying to put out as much information I can find on this issue so that it can be resolved for not only just me but the multiple other people that are having this issue. Anything helps!

I may have missed it but did you remove the trim panels to have a closer look? That sound is definitely electronic. If it was from the brake pedal or shocks it wouldn’t be the same pitch and cadence each time.

The other forum also confirmed that bc that many trucks wouldn’t have the exact same problem.

When I was truck shopping a few dealers tried to charge for an aftermarket tracking/antitheft device. I didn’t see it in person and maybe it was just this dealer but I thought I’d throw it out there

Like Wes I’m leaning toward the brake controller. It’s possible that if it’s aftermarket the installer used a different power source. Again, not likely but possible.

I think what might help is pictures. However you can do it post some of your under dash area. Also please confirm it’s not coming from your dash or door speakers.
