on/off overdrive light not working
Hello everyone, I have a 1994 F-150 302 E4OD. The on/off overdrive light on the gear selector isn't working when turn off O/D The switch is functioning properly, but it's aggravating that the light won't work, do any of you know how to fix this problem? It would be greatly appreciated!!!! On another note, I just wanted to say this website is AWESOME.!!!

The light is just a simple output from the computer. The computer turns it on and off in response to you cycling the switch. If you poke the switch, and the computer then shifts the trans, the switch, computer, and trans are fine. The problem is confined to the bulb, the wire, the driver in the computer, or connectors along the way. My bet is on the bulb.

I know the collar on the shifter comes off. I am not sure if you can access the bulb from the end or not, just don't know. I would carefully take it off, but I am not sure that that will not damage the collar. Maybe someone will provide an answer as to whether or not it will work.

From what I understand from the Ford parts guys, this shifter and parts can be bought seperately, the complete shifter, the push button switch and the switch cover, have seen numerous times that the selector handle wiring behind the steering column cover has broken through the outside pcv coating and rubbed the wires until broken. Have never replaced the switch for a blown bulb. Broken Wire

My thinking was either the bulb, or something not making contact in the general area. I just don't have a manual to see or read information pertaining to that area. Just thought I would pose the question to see if anyone had run across this before, so I could save some time troubleshooting. Thanks again for your responses. Brian
