OD button not working

I just noticed my OD button isn't working, no light just dead, the van is running as if in OD. Seems like it's maybe just disconnected or maybe something else? Sorry if this belongs in tranny thread, thought i'd try here first. Tranny is otherwise in excellent shape, shifts well and smooth. THX

Year, engine and tranny specifics usually help, but I'll take a stab at this anyway. As far as I know, all the fords with OD buttons (electronically-controlled trannies), the button is for turning overdrive OFF. Default is for OD to be ON. So, my guess is that either the button/switch is bad, or the LED/bulb is bad, since you think you still have OD.

The circuit to the OD switch on the shifter is fused in the interior fuse box, check that first.

The wires that come out of the shift lever are very fine and fragile. They exit the lever at the base and typically break just as they exit. You have to buy the whole lever and switch as one unit. If you remove the steering wheel cover, you'll see the wires. Good luck, John

If the insulation on the wire wears through it often will short out on something metal in the column and blow the fuse. Replacing the lever is the only proper repair for shorted wires. In an emergency I have put a little tape on the wires to get by for a short while. But the wires must be very flexable and tape will stiffen the wire.

How does that button assembly come off? if i need to repalce the switch. Actually I am assuming the fuse is blown, so maybe if it works don't fix it, will be my choice of action, or non-action. I never drive with OD off anyway, just wondered if there was something up with the tranny is all. THX

A thin pick or fine flathead screw driver will allow you to pry under the end cap. Once that is removed you can slide the switch and light cover assembly out.

On a related note, has anyone had success replacing the LED in the switch? Mine no longer lights up but the switch still works fine. I am not buying a whole new switch for a $0.03 LED. Stupid fords...

I popped it off it looked liked somebody had tack glued it on or something cause three of the little prongs were already off, then it slides right out. I haven't checked the fude yet, but if it's fried, then I am gonna glue it back in and forget about it, i never used it on my F-150 anyway.
