Air Dryer constantly blowing; company refuses to fix it

As long as you are maintaining air pressure don't worry about it, just drive.

Mine truck was doing the same thing recently, about every 30 seconds purging the dryer. No leaks. Replaced signal line, purge valve and governor. Ended up replacing dryer and that fixed

Is it a quick pssh when it purges or does it slowly build when it comes on? I had my air dryer replaced a while back (wouldnt build pressure) and afterward it purged very slowly every 30 sec or so cause the dude who put the new one on didn’t hook up one of the lines going to it. Iirc it was the one telling the governor to shut off.

 

Shut the truck off and do the air brake test per the CDL manual. If you lose air you have a leak. Write it up as an air leak and maybe they will take it a little more seriously.

 

Turn on your manual fan switch. If it quits, it's in the fan hub. Can't hear it with the engine running, and can't spray water on it with the engine running, and it won't leak with the key off. In my case, it wouldn't even leak with key on.

Worth a shot.

 

Please don't park next to me for your 10 hour break!

 

That doesn’t bother me as much as the macho big rig driver sitting in the center of the lot with his ****** ******** engine fan engaged all night long with the engine on high idle buttoned up tight on a cool comfortable night while the rest of us are sitting with our windows open and enjoying the breeze.

nothing like trying to sleep with a jet engine in your ear.

 

Like last night at 2 am some #######
Blaring his stereo in an otherwise
Nice quiet comfortable peaceful parking area with just about everyone had windows down or sleeper doors open. Thought that driver was in for a beating.

 

Right up there with the trainer teaching his trainee to back at 2am - with a back up alarm.

I got out and yelled at the guy and he thought I was being unreasonable, but he stopped.

 

Pull around back at the next scalehouse w trucks parked in back.
Ask the inspector for help locating the leak
Bonus points if it is near a motel.
