O/D Button problem

My over drive button seems to work about half the time. Anybody have any ideas? Is there any connections I can check?

The circuit is very simple. One wire is hot when the ignition switch is on. When the button is pushed, it sends battery voltage to the PCM. Each time the PCM receives B+ from the switch, it toggles between O/D off and on. Ignition on default is 'O/D on'.

The pushbutton switch itself could be dirty or otherwise defective. I'd say that this is the most likely cause of intermittent operation.

High mileage vehicles sometimes wear through the wire insulation or break the conductor from the repeated motion of the shift lever. Worn insulation blows the fuse but a broken conductor could give the symptom that you have.

There is a small 2-wire plug connector at the forward (lower) end of the steering column. You can give it a look but it isn't very likely that it's loose.

If you determine that it is defective, I have a working one that I can get rid of. It'd be much cheaper than getting one from the dealer! It's a simple removal procedure too, which I can guide you through.

Check out that circuit's fuse, first!
