4Wheel Wont Turn Off

Ok here's the scenerio. I was stuck in some mud and used 4hi to get out. There was a lot of slipping.

Here's what's going on now. I've noticed that my 4 wheel is engaged. I did some looking around and found out that the vacume switch under the battery doesn't work properly. It will engage but not disengage. Ok so that's bad, no big deal. So I disconnect that for the mean time. But now my front hubs are still locked? Any suggestions? If I remember right the hubs are electronically controlled. So I was wondering how to turn them off I guess? Thanks for your time.
