None of the seat bladders inflate, can hear pump motor run
If I activate the switches for the lumbar or side bladders, I can hear the pump motor spinning.
- Does one pump fill all of the bladders? I have a hard time accepting that all 4 bladders would fail at the same time.
- What is the failure point that would affect all 4? It seems possible that it's the pump.
- Is there a solenoid that directs the air to specific bladder, or a valve that can fail?
- Where is the pump and how can I check? I've seen posts that show getting to the bladders without removing the seat. Is it a must to take the seat out to get to the motor?
- Can it be the seat control module? I've seen references in other posts. Where is it?

Thanks for the link: I'm going to pull the seat today.
Thanks for the suggestion. I'm a newbie member and just updated my information: '99 Vert, Manual trans.
Some basic info about your car like year, manual or auto trans, Coupe, FRC, Vert or Z06, mods etc would be a big help to someone trying to help you with problems on your car. That info should be either in your profile or the specific post asking for help. 
This thread should help you out with the Lumbar issue:

No joy. Took seat out pump works fine.
Seat comes out easy enough. Took out pump. Cleaned it up and fresh lube, though it was pretty clean to start. Tested the pump off the battery terminals and pumps like crazy but after reassembly none of the bladders fill 
I'll have to take seat out again but not sure where to look.
What sits between the pump output and the 3 hoses going to the bladders? Can it be an electronic issue?
