Air Suspension Leak Down after Sitting 2 Weeks

[Doubeleive]

i'm kind of the ingenuitive type, I would probably take a shock off, rig up a air line and stick it in a tub of water, like tire shops do to check for leaks
repeat with each shock until the leak is found. wouldn't take much maybe 10psi, a bike tire pump would work. air lines are usually just a compression fitting you could find at any hardware store.
i know very well the dealer should be able to find it, but sometimes you gotta do what you gotta do
this would not void any warranty, you simply locate the leak and mark it, then take it back to the dealer and point them to it, then they can verify on there own.
maybe that's too much work though, not sure how hard the shocks are to R&R on the new trucks

Dumb question…

1) Do dealers get paid by GM for inspecting the problem?

2) Do dealers get paid a lower hourly rate for warranty repair?

It just seems like if I bring something in under warranty I get the working as designed. No warranty they’ll gladly charge me for new parts, needed or not.
