    Hey guys. The left wing on my 8.2 wont retract. I can put it against a curb and push it in, it takes some force to push it back in, and I can extend it out, but it wont retract.
    Do I have a bad valve? Which valve is it?
    Thanks in advance!

    Remove the pump cover and check the coil with the red/black wire for any dislodged or loose wire connections. If they're ok check the coil for magnetism while a helper holds the left wing retract function on. If it doesn't have mag check the red/black wire with a test light, should have voltage. If not, then there's a poor connection in the harness somewhere between the controller and the coil (bumper plug, controller plug etc) so check each one over carefully and back track through the harness with your test light until you find it.

    If it does have mag, then either the valve is stuck (damage or debris) or you have an issue with the wing cylinder. Neither are too common but if it's equipped with Smart Locks they can go bad not allowing the cylinder to retract or if it's been heavily neglected on fluid changes there may be debris in the system thus causing a sticky valve. But again neither are too common, it's much more likely to be an electrical issue.
