[QUOTE="Ciras, post: 1433722, member: 22020"] A vacuum leak will not prevent the transfer case from engaging. Nor will it prevent the indicator lights from coming on. You were correct that the problem is electric. Firstly, check the relays associated with ESOF. Corrosion is a fairly common issue; clean or replace. Ensure that the relay has not failed by testing with a multi meter. Each prong should read 0 ohms to the corresponding pole. Also be sure that the relays and fuses are receiving 12v. Remove the transfer case motor and apply 12v power to confirm operation. Ensure that the motor is receiving power. The results of the above will yield the answer or point to where more troubleshooting is required. [/QUOTE]
