I just bought it 12/29 but got home to late to take for quick ride. Get up Sunday and 4x4 will not engage. It has been cold here for the past week or so...not sure if that makes a diff. Dealer has been closed since then so just fishing for suggestions. I did try again today still no luck. Thanks for any advise.

Unless you have a heated garage to warm it up take it for a ride for 15 minutes to loosen and warm things up and try it then. See if that works for you. I just came in from a short ride in -19 C with my Uforce 500 HO and no issues.

I have a wood stove in garage and really don't think the cold is issue. I do not hear anything trying to move at all when button is pushed. I also tried today driving around a bit and still nothing.

I assume all the fuses and electrical connections have been checked. How about the dash..any odd or flashing lights ?

I checked fuses and relays...even swapped relays around t make sure. nothing blinking or odd on dash. I did start pulling plastic to check harness....then it hit me its only a day old! dealer is gonna pick it up early next week to take a look.

...Is the front break involved at all? looks like 1 wire shares with front brake lever or possibly just sharing the connector!
