Edit: just packed a few guys in the truck and compressor kicked on and shock bladders are full!!! Do I need to adjust the height sensors maybe?
Edit: end of a 1.5 hr trip, everyone hopped out and I cut off the ignition, airbags weren't full.
Edit: I started the truck, compressor turned on and shocks filled. Had some people sit in the second row, it kicked on again. I squeezed the rubber on the shocks and they felt like they no longer had air in them (the drivers side felt empty and the passenger side felt like it had some air but not full. At this point I'm suspecting the air lines?
