Hi,

Yesterday I went to put my 400 in 4wd but it did not work. On the dash you can see the picture of the four wheels with the two rear lit up. When I swap to 4wd that picture just goes away. I checked the relays and swapped them around to test them out. The middle relay clicks when I move the switch so I'm guessing the switch is good. The relays seem to be good. There are three identical relays (high beams, 4wd 1 and 4wd 2) and I swapped them all around in different configurations with the same results.

Is the problem likely the actuator then? I've not been able to find confirmation that a bad actuator would make the display of the four wheels on the dash disappear?

Thanks

Got me on that one. A disappearing display usually isn't from an actuator or gear problem. More of an electrical issue like a circuit board or connection issue.Could water have gotten in somewhere it shouldn't?

Thanks for the reply

I don't think water would have gotten in anywhere. It has very low miles, doesn't get many rough rides (usually very tame trails) and is stored inside. I do wash real good after each ride but that shouldn't cause water to get into anywhere it shouldn't.

I'm pretty stumped on it, also. Not seeing anyone else having the same issue online or anything. I don't want to start replacing parts that aren't needed to be replaced.

Also while troubleshooting I did remove the two bolts holding the actuator onto the diff and noted that the actuator was sealed onto the diff really good. I was not able to pull it off by hand and did not use any tools to try to remove it, i just put the bolts back on. in my mind, that was enough to prove that no water had snuck in behind the actuator or anything like that.

As I recall there are four bolts on a CFM actuator so...and that wouldn't cause any problems.
