I am by no means a SkyHook (or even other) suspension expert, however I recently did a fork seal and oil change on mine, there really isn't much to see inside the top of them even when separated to replace the seal; they are much like other USD forks and the springs would seem to do most of the work.
The electronics are only in the left leg and handle compression/rebound damping only and it was not clear to me exactly how that might work. The right leg is just a normal fork and has the preload on the fork cap. Aside from checking that they aren't bent, I think I'd start with preload and check whether it has been set to maximum (fully turned in) and is thus reducing fork movement. Beyond that, I'd pull the legs one by one, starting with the right one, and see if you can compress them when they are off the bike. If not, then I'd probably at least pull the fork cap, drain the oil and take a look.
Unfortunately, pulling the legs is a bit of journey, see the fork seal thread for the steps I went through.
