RE: stuck in 4 wheel drive
Take the battery and the battery try out. You will then see the actuator for the front diff. It has a vacuum hose on it you can disconnect (don't forget to plug the hose). If this helps your 4wd light problem, the vacuum switch on your transfer case might be bad (very common problem on these vehicles). If it does not help, it may be the motor that engages the transfer case.
