Low air buzzer malfunctioning.

[fireman5]

Hello. My low air buzzer doesn't buzz and the light doesn't light when I turn the truck on even though the gauge shows no air pressure. I'm wondering if it's the buzzer and light are bad or could it be the sensor?

get your VOM out & look for power to buzzer?.... easy...... You do have a VOM?

No power to the buzzer/light, it the low air pressure switch, (under the dash)
