stuck valves

when i try and air up the back of my truck the valve is staying open so the bags cannot inflate. does anyone have a fix for this problem other then replacing the valve.

open it up and see what is stuck in there. Clean the diaphram with some air tool oil. and reassemble.

did you just put them in or have they been in for awill

been in for a while. started as a slow leak but know they just stay open.

what kind are they but you should be able to take apart and cleen them

open them up, time to learn.

sounds like they just need to be oiled just do as the cat above said just open them up spray in some oil or w/d 40

test it before you open it hit it with some wd before you even take them outta the truck, just spray in the valve and hit the switch a few times maybe even tap them with a hammer(lightly) and see if you can free them.
