I have a 2017 Zforce 800 Trail and the four wheel drive recently quit working. The funny thing is it will engage if I put it in diff lock. Any ideas?

[2015 Z Force 800 53/Trail EPS]

The slide control is two positions on the same geared slide and the first position is just 4WD so in order for the diff-loc to work it has to slide into 4wd first. That being said the "step-one" position for the actuator isn't working. That's most often from a bad switch but also a bad connection. It can also be a problem with that actuator internal electronics...but check the switch first. Work the button a few times...it may have got water in it.

Ok I will try that thanks !
