Hi I have a 92 Volvo white gmc. I need to know where the low air buzzer or alarm is located. The air pressure gauge will drop under 70 and the red light comes on but it doesn't make any noise. I'm thinking that I have a bad switch or buzzer. Thanks in advance.
92 Volvo/White/GMC where is the low air warning buzzer or alarm?

Is it cabover with 7'' headlamps?
there were different cabins in 1992, I remember there were air lines between seats, under cover used like a desk.
Other place - rise grill and u will find air switches
I had 1989 volvo cabover many years ago, but now old volvos dissapeared and only volvo cabovers I can see on road are FH, and I'd say first generation FH is really rare on road, generally version-2 -
Hi Pablo. No the truck is not a cabover. I looked earlier today and there is an air manifold on the left side under the dash. There are a few sensors or switches I just do not know which are for the low air buzzer or alarm.

it is easy to understand what air line is for. Air lines are color marked:
Black - supply (wet tank)
Green - primary (rear brakes, by ECE #1 tank)
Orange - secondary (front brakes, by ECE #2 tank)
Red - park brake and trailer supply (#3 tank)
Yellow - Park brake control
Blue (yellow in EU) - trailer service brake control
And other colors are used for accessory tank (#4 - transmission control, sleeper air bags, horn, seat suspention and other) -
So would it be the solenoid or switch that the black air line is going to?

I replaced the low air switch with no results. Im thinking that I have a bad buzzer/speaker on the cluster and also the little red light on my air pressure gauge quit working. Any ideas?

Still trying to figure out a way to put a buzzer on this truck. Any help will be appreciated. Thanks in advance.
