My overide button does not work (backs up wide open). And also my 4wd does not work the light don't even come on. I just replaced bearings in the left front. When the bearings went did this go to? where do I start?

 

I have since found out that this is possibly a switch on the gear shifter. My neutral light stay on. Has anyone ever replaced this switch? Please help!!

 

The switch does go bad in the shifter.I would check the bulb in the 4x4 swich first because if it is blowen 4x4 wont work.On your reverse limiter are you sure it hasnt been disconnected.When they go bad most just unplug the black wire and forget about having a button to backup just hold it in for 4x4 in reverse.
