I have "fixed" them several times. Taken them off the truck, disassemble, replace o-rings, reset the 'park' button, etc. Test them on a shop compressor, works great, put them on the truck, works great. Use the truck a month later, everything is crap. They wipe to the right once, and then nothing. Sometimes they hiss, and every once in a while 1 will pop and then start wiping. Both never work. The park button seems to be my issue and is like a silly feature.
I like the rain-x idea.
Find some old style wiper motors. Easily rebuilt and work very well. I also don't like the Newer style with the red button. They don't seem to have the same power as the older ones which translates into poor performance at slow speeds. You also need to clean up the air switch. They get clogged with junk from the air system. I have also gone with DOT hose instead of that rubber stuff. I'm able to use compression fittings so I get no leakage from my air lines.
