2001 Trooper, auto trans, 4wd. THe check light started blinking yesterday. The 4wd shift lever may have been accidently moved. I tried to adjust back to where it normally is, but light won't go off. Does anyone have any suggestions? I did schedule an appt at the dealer where I bought it at 10 years ago. They are no longer an Isuzu dealer though. Would that make a difference? Is Isuzu still in business?

Thank you in advance for your reply.
