2000 S500 front passenger seat air pump
 

has anyone encounter this problem?

this pass weekend, i sat in the front passenger seat and hit the slide button to slide the seat back and in doing so broke one of the air connector where the read plastic hose connect to what seem to me is the control modual for the lumbar support.

now everytime the car is started, the air pump pumps for about 1 minute and stop.

i check out the problem, the red plastic hose broke off from what seem to be a connector to the air pump

do i need to replace the whole modual or just the plastic peice where the red plastic hose is connected?

is this easy to replace? if so where can i get the parts and what is the official name for this part.

any suggestions will be greatly appreciated . . . thanks!
