First I didn't mind and didn't care if it worked or not but my back is starting to hurt now I really need it. It's not working at all, I can't hear any pumps running or anything at all. I can't hear any air leak sound either.

How is the lumbar support powered?
Where is the pump?
Where are the fuses for it?

 

I'm not 100% sure but I think it's the same pump as the soft close doors. Try taking the 20 amp fuse under the back seat in and out. That solves my problem of the soft close not working. There's a thread I made about the door issue and someone posted a pic of which fuse it is. I'd search for you but I'm on my phone it's hard to navigate through the site.

 

thanks man I'll try the fuse thing for now. If this fixes it I don't mind doing this 'resetting method' every few days to get my lumbar working.

 

no prob...keep us posted

 

didn't work looks like I need a new PSE pump to fix the problem... screw that!

 

I got a used one(PSE pump) for sale, $150 shipped.
