Please help.,no aux air
Got ready to pull out and after cranking I noticed aux air at 0, front/rear gauges are fine. Got out with engine running and can hear a loud air leak. Figured out it was coming out of the very bottom of the air pump located above the rear drive axle between the rear drive tires. Looks like the bottom of the pump may have an actuator or seal that has blown. Any info would be greatly appreciated, it a 2002 H3-45. Thanks in advance

Can you post a photo showing where it is exhausting?

Are you talking about the air dryer, not familiar with any pump? Also, who is the converter?

Take a deep breath and relax. It is not the end of the world and it could be a rare but real problem easily resolved. Based on the limited description it sounds as if it could be a relay valve. A quick check of gauges might help.
With the engine on high idle look at the primary and secondary air system gauges. What are their pressures? If they are not over 75 PSI the aux air will not build. If the air flow you hear is in the rear, remove the fender and try to identify the source. From that point on you can arrange for a repair.
If it is a relay valve, maybe $60 for the part and a couple of hours maximum for replacement. If it is a dryer, a little more, but sometimes a tap with a stick or hammer gets it working again.
You should be able to run your aux compressor and build aux system air regardless of what the leak source is.

when I get back to where it is I will post a pic, I assumed it was an air pump however it could be a drier???

I have 3 gauges, front/rear and Aux, the front and rear is hold at near 120, the aux gauge stays on zero. Even with the engine running you can hear a loud air leak noise coming from what I thought was a pump above the rear drive axle. On the bottom of this device in the center of the housing is what could look like a diaphram with an 11mm nut on it, the air is strongly coming from that spot, when i turn the nut it changes the sound of the leak and if I push up really hard on it I can almost make the leak stop. When i use the brakes the front/rear level drops and I get a low air pressure alarm. Thank you soo much for the help.

Sounds like the purge valve on the drier.

Coach Net sent out a tech and he said its the drier. Thanks to everyone for the input, sure makes a rookie feel good to have access to all the knowledge and kindness on here. God Bless

Good to hear you’re headed in the appropriate direction.
How long did it take for Coach-Net to get someone to your location? What kind of vehicle did they come in? Seem knowledgeable? Trying to gauge quality of Coach-Net response. TIA

I just experienced the same leak ….It’s pretty easy to rebuilt the diaphragm valve (kit is $15) ..
um make sure you block it up for safety before you go under it!!

I am pleased with Coach Net, it took about 1 1/2 hours. They call each time the tech is scheduled to arrive to make sure they made it. The company and truck they sent to me is what looks like an 18 wheeler roadside repair setup. Obviously when in the heat of the moment of a breakdown it never seems quick enough, they do communicate with you really well. This si the 2nd time unfortunately I have used them with this coach, both times I was pleased.

Those able to use Coach Net are fortunate. Due to the Legacy of my coach they will not even talk with me.
