good morning my name is ***** ***** I will assist you may not have air brakes but you have an air system that operates other items. if the light and buzzer are on, you may have a clogged dryer filter, an air leak somewhere or the air compressor itself may have failed. has anything been done yet or checked?? Roy

Hi not much has been done , I do not hear any major air leaks , when the system does operate , I found the cab level sensor arm disconnected the other day I reconnected the linkage arm and everything worked ok for about 1 day then on Sat. I started the truck and the light and buzzer stayed on again. I sometimes can hear air puttering out by the , what I think is the compressor at the bottom , i push up on what looks like the relief valve and the puttering stops, however the light and buzzer still stay on

ok, thanks. it sounds like the purge valve at the dryer is exhausting. common failure. if it is bad, it does it constantly. I would start there and replace that valve. pretty easy to replace. you need a screw driver and snap ring pliers to replace. do you have an air gauge??? if so, what pressure do you see?? Roy

No pressure guage on the truck, maybe I will install one, I will change the purge valve on Mon. ,,, let you know the results
