My 2005 polaris 800 will not go into 4 wheel drive while in reverse with the over ride button pushed in. 4WD works fine in forward. Also, it had worked one day and then not he next and then again the next day and now nothing again. I have replaced the over ride switch and that did not cure it. Thank You
