SOURCE: 2001 GMC Yukon Denali XL -intermittent dead battery

The wiper should not move regardless of battery change as the wiper switch should have isolated it.It seems to be the only ,as you say,strange thing and would be inclined to believe that that is the probable cause of your fault.Do like your testing method and hope you track the fault down.Good luck and happy new year.

SOURCE: trying to install an aftermarket stereo 1994 GMC 1500

You have to unplug the old radio. The radio isn't the part in the dash. That is just the control to the radio. The radio is actually under the dash above the accelerator pedal. It should have the power wires, speaker wires and antenna wire going to it.

Knocking noise on driver side font on 2005 Yukon.

with out more info it sounds like it could be the drive axle could be going bad if it's a 4x4 or possibly one of the pins holding the brake caliper in place has backed out and rubbing the inside of the wheel. I would also check the wheel bearings to make sure the wheel is not loose and making the noise you hear.

My 2005 Yukon brakes makes loud noises and vibrates as truck comes to a stop, brakes look good!

Have a look at the discs as the inside face may be badly scored or even missing. Check that you have at least 3/16 " pad on both pads. Check the condition of the wheel bearings and the suspension and steering joints for wear and loose.

Bose amp

Next time it does it take your fist and hit the top of the console armrest, toward the rear of the armrest, if it stops suspect the Rear Seat Audio module, I'm assuming you have one because I've replaced 3 in the last few months for this exact problem,it sounds like an alt. whine up and down with the engine speed, yes the amp is bolted to the floor under the console, you can pop that RSA module out and let it hang until it makes the noise and then lightly hold it and tap on it to see if the noise goes away. The RSA needs to be programmed to the truck at a dealer.
Hope this helps

2005 gmc yukon security light on cluster is on

The security light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM. These 3 parts are in CONSTANT communication. If the key is in the ignition, these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. There is where the security light turns on and shuts down your vehicle.

My 2005 yukon denali has been making chirping/whistling noises inside the cab when driving and after ignition has been shut off. It doesnt happen all the time just here and there

Sounds like your air conditioning. If you notice it while driving, your freon charge is low. If it is noticeable only after the ignition is turned off, that is a pretty common sound.
