Talking Lumbar Support won't release pressure

Hi, anyone know how to get the lumbar support to release? While driving my daughter to college, I increased the pressure on the lumbar support. The lumbar support inflated, pushed out he back of the seat some, but won't release pressure? All of the other seat switches work great. Any ideas, no Spike, I don't want to use a knife.......Thanks in advance. By the way, the truck worked flawlessly coming across the desert in 112 degrees. Can't wait to teach my daughter the finer points of 4-wheeling on some of these great Utah trails before I head home. Phil

ps, averaged around 16-17 mpg fully loaded traveling 80 to 85 mph, did about the same in our Land Cruiser (chase vehicle), did lose a brand new windshield in the Land Cruiser outside of Vegas, bummer

There is a deflate valve, maybe a loose connection or faulty valve.

You will have to pull the seat cover off, check on rave how that is done. The valve is an integral part of the bladder afaik.

My guess would be a bad contact on the seat switch. The contact for the "increase pressure" is good, but the "deflate" contact isn't. Possibly take the switch out and see if it can be cleaned? Or check the Rave wiring diagram and see if that circuit is getting power past the switch, and jump it if necessary.

here is what the bladder looks like. the pump is in a black pouch in the seat back. Pump is in the black plastic case, release solenoid is the silver barrel. The white plugs are inside the seat and connect to sea controls via the grey plug. You can test the pins directly on the grey plug. refer to RAVE for pin diagram. Careful removing seat cover. There are 2 and sometimes 4 metal 'U' clips holding the cover to the bottom of frame. The plastic 'J' hook (long black plastic hooks) break really easily......
