it could be the air conditioning clutch going out. to check turn your car on and idle it with ac on and hood open. at the ac compressor it will have a pulley on it with a clutch that engages when the air conditioning is on. if it engages and disengages it can be the clutch itself has gone bad, the ac clutch will also disengage if there is not enough freon in the ac system, will also engage and disengage if the pressure gets too high in the ac system. Depending on the year of the vehicle it will disengage at full throttle and come back on when you are not at full throttle.
If it is a metallic sounding screech for example take a coke can and drag it across pavement kind of sound it could be a bad compressor or a bad ac clutch. If it is a more rubbery sound for example a car spinning its tires kind of noise it could be a loose belt.
1. Check to make sure all belts are tight under hood
2. start car and look at ac compressor to make sure compressor pulley is turning and that the fan clutch is engaged spinning

You normally can't disable alarms as there is a computer in-between the switch and the light on the dash. You have to fix the fault, not find a way around the problem.
The easy way is to connect a professional grade scan tool computer, check for codes and read the data that is registering the problem.

To remove the center console on a 1999 Mercedes Benz ML 320, you can follow these steps:
Remove the shift knob by twisting it counterclockwise and pulling it up.
Remove the shifter trim panel by gently prying it up with a trim removal tool or a flat-head screwdriver.
Remove the ashtray by pressing the release button and pulling it out.
Remove the screws that secure the center console to the vehicle. There should be two or four screws, depending on the vehicle's configuration. They are located at the front and rear of the console.
Carefully lift the console up and away from the vehicle, taking care not to damage any wiring or connectors.
Once the console is removed, you can access any components that may need servicing, such as the radio or climate control module. When reassembling the console, be sure to reattach any wiring or connectors and secure the console with the screws in their original locations.
