Service 4WD Light

[The Ledge]

I have done a search and came up with no matches on my Title Topic so here goes - I have a 2005 H2 with 31k miles. Do no off roading per say and have used my 4WD Hi and Low only for winter snow road conditions. I'm still covered under the MFG's warranty and hoping its just a sensor/cable issue. Has anyone had a similar issue that was not a sensor problem and if so, what was the extent of your damage/repair? Thanks in advance.
