No O/D on the gauge cluster or when the button is pushed

[NewShockerGuy]

Figured I'd ask. I just changed my shifter lever to a chrome crown vic lever. Removed my old lever and put the new one in. Pushed the overdrive button and it didn't illuminate on the dash. Thought that was odd.

Tested my old lever, that didn't work either. Turned the truck on/off and noticed the light on the cluster wasn't turning on like the others do. Took the cluster out to find out I forgot to put the bulb in ...opps. I put the bulb in and still doesn't turn on. I tested both lever switches for continuity and they both work so I know the buttons are good.

I have zero check engine lights and no issues with driving/going into gears.

I checked all the fuses and they are all good. The last time I pushed the OD button was probably over a year ago and it did work.


I will have to take it on the road and push the button to see if the RPM's change and perhaps something just isn't illuminating on the cluster. But as it sits now it doesn't seem to be working?

Update, as I fixed this last week but forgot to post here.

Anyone that takes apart the dash and disconnects the headlight switch there is at least one 12v wire that the OD/cluster uses so if you disconnect the headlight switch the OD button will not work/illuminate on the dash. Had no clue they were related at all but on the other ranger forum Ron posted a wiring diagram and sure enough it was.
After plugging it back in everything works as it should.
