Scooter,
Have the same issue on my 98 Overland. Looked at it last night, as a matter of fact.
The old hose is brittle and a piece of crap! Looks like here is a wire running along with the hose, acting as a "heater" to keep it from freezing. My guess is it heated the hose, with no water in it, and dried it out - go figure.
Only soultion I have come up with is to disconnect and pull the frig part way out. Then I can get to the hose at the ice maker.
Gas line and 6 screws for mine to come loose. Beats the cost of taking it to a dealer for repairs!
Fix it yourself if you can.
