I replaced my valve with a used eBay valve and everything’s cool now.
There’s also a million other little connections around there that need looking into, but mine was solved with the ‘new’ valve.
Also, on my ‘02, most of the connections were different than what more common ones were, ie when looking at forums, everyone was like all that stuff is right here, but on my truck it was a diff location and different connections.
Either way, good luck. Wasn’t a fun thing to chase down, or in a convenient location(s) either.
