    im new so please bare with me, i have 2002 kw W900L with a C-15 the truck low air light will not shut off. the air pressure is reading 120 and after doing a few internet searches i bought a warning sensor that screws in to the air junction box in the dash. this help a bit it will turn off now 90% of the time but only when it hits 120psi and some time i have to tap the brakes when it hits 120 and it will shut off. the light will come on around 110ish and not go off until the pressure hits 120 again. so i am a bit lost now, I cant find any thing else that points me in the right direction other then a stealership. any idea would be a big help thanks

    If you have the dummy lights in the narrow black panel in the visor panel there are two screws that hold that panel in, pull the panel out and on the back there are little white micro switches, IIRC they are marked, find the one for the buzzer you want to mute and switch it.

    If you have a water leak and it leaks down onto the sensor, this can trigger it. My Pete did the same thing, put silicone on top of the sensor, haven't had a problem and also fixed the water leak.
