I have a 2014 outlander xt and I can’t get it to switch from 2×4 to 4×4. I’ve already replaced the actuator and I manually put it in 4×4 mode when I was putting it back on. But still can’t get it to switch back and fourth. How do I tell if the switch itself is bad or not? I know it’s not the fuse because the 12volt plug and winch works and it’s all on the same fuse. Just not sure how to check the switch.
