After leaving the windows down during a heavy rain, the seat adjustments begin acting strangely with the seat making adjustments even though the controls were not being adjusted. Now the controls don't work at all and the lumber is fully inflated (otherwise the seat position is okay). It is a 2004 xtype and I would simply like to deflate the lumbar. I took the seat out and flipped it with hopes of manually deflating; but, I cannot figure out how. What is required to manually deflate the seat? Is the pump collocated with the bladder inside of the seat? If so, how do I get to it as the seat cover off?
