Never had the light flash, but the other day I was running in the back of my property and had to go through a small mud hole. I tried creeping in 2wd to avoid a mud bath and of course I started to spin. I hit the 4wd buttom (of course I was stopped) an nothing. Still 2wd. Tried going in reverse a bit then forward again to maybe see if it just wasnt engaging. Nope. No 4wd. So after hammering it to get out of the mud hole and spraying mud everywhere after just washing the damn thing lol, I made it back to the house. Checked the fuses and found the 5a fuse of 4wd/2wd blown. Replaced it and all is well now, but why and the hell did it blow the fuse. I may have hit the button while rolling forward the other day, would this of caused it? I havnt even had the thing a week yet and already having issues. What gives? Anyone else have this problem?
