Have my prospective son-in-laws HJ105 1999 mod in garage. Can't select Centre Diff Lock (CDL) by either the switch or engaging low range. Fuses OK. No activation lights in dash. Any suggestions? Was just in Introduce myself 'New Member' forum but should have posted Q here? ** Further to the story. Now know that the heater doesn't work. Doesn't appear that power is getting to the centre console printed circuit board.
