My driver's seat keeps sinking down

I had a seat that did the same. Clipped a bungee cord on the handle a hooked it behind the seat to keep the handle raised. Worked like a charm.

 

My seat would raise when I pulled up the handle. The bungee kept the handle up and the seat wouldn't sink.

 

Ok, I had a truck that the air switch on the seat only leaked when I started the truck in the morning when it was cold out.

 

That was your air bags leveling after you dropped your trailer , i assume you did not dump your bags , if so stop doing that its hard on equipment

Take it to the dealer its under warranty , good luck

 

I wasn’t going to comment on this thread, but the above comment is absolutely wrong.
You can “lose” air every time your air dryer pops off, every time your cab goes up and down, and every time your suspension needs to readjust.
