My pneumatic adjustment doesn't work on my 2 front seat... Checked fuses they are all good..checked behind the back rest, hose are connected.i think that i don't hear the pump. Where is the pump ? Is it the same as the door lock? Anyone had problem with this? Thank you

 

Check hoses under front seats. There's also a canister which air hoses connect to behind the passenger side fender. I moved mine to the engine compartment so as to have easy acces in the future.
