C43 pump in the trunk that controls seat pressure and Ect...?
Does anyone know the pump in the back that is located in the trunk. It sort of has a winding sound when you are about to start the car or when you change the pressure in your seats? Well I noticed when im about to start the car I hear the pump winding longer then usuall and the pressure in my seats doesnt always work. Can the pump be going out?

Probably a cracked or disconnected hose. The most common failure is the T joint in the back of the front seats for the side bolsters. Do all of the bladders deflate or just the side bolsters?

The driver side the left side of the seat booster doesnt inflate but the right does. I was thinking it was a loose hose. But recently all the options stopped working like the pressure for your back and lower back doesnt work some times it does. I thought it might be because of the pump in the trunk im not sure what its called.

all of the options defoliate but some times don't inflate. The driver side blade blooster on the left doesn't inflate at all but the right one does. Im not sure about the passenger seat but probably has the same problem.
