I purchase a 2000 GU ST yesterday and didnt get around to testing every light etc until today, when I engage either hi4 or low4 the light on the dash doesnt come on, I have asked the people I bought it from if they knew if it was working or not. They said last time they went off road about 5 months ago it was, but when they did a heart transplant about 2 years ago they experienced what I am now. He said they took it to their mechanic and he really didnt touch anything and it started working, the mechanic said it must have been a loose connection or something, as they and their mechanic are a 5 hour drive from where I live I'm hoping some people on here amy be able to shed some light on what could be the cause and were to start looking. I've ordered a workshop manual for it so when it arrives will be able to get the multi meter out then.
is there a possible fuse?

Thanks in advance
