Having overdrive/autolamp fuse issues? Here is how you fix it.
Ok, I've seen several complaints and issues about Fuse #29 constantly being blown. This fuse controls 2 significant systems: the auto lamps and Overdrive. The problem is wires in the column that get chaffed and short out in the column shifter. Remove the surround, space the wires, and wrap some electrical tape around it. Should be golden. for those who need help getting the shroud off, here's how you do it:
1. Disconnect battery negative cable.
2. Remove lower shroud. (Makes #4 easier if you do this first).
3. Insert key into cylinder and turn to RUN position.
4. Use a pointed tool (punch or small Phillips screwdriver) to push the release pin in and pull the whole lock cylinder out. The pin is on the bottom of the housing that holds the lock cylinder.
5. Remove tilt lever if present by unscrewing it.
6. Remove upper shroud. Pull gearshift lever down to 1st if needed.
Remember that the spot in the wiring that needs mended is at the point where they exit the shift handle. The wire then runs along some plastic tabs to a switch behind the dash above the column. There is a plug there, you'll need to pull up some slack. Unhook it from the column and tug it down where you can get to the plug enough to unplug it. Its buried in there very inconveniently.
Then pop the cap from the switch and draw the wires out through the handle just enough to work with the bad spot. Tin your wires, solder back, tape. Only use enough tape to cover the wire or it won't fit through the handle when you pull them back through. {you can use an ohm meter to test switch function new too, the switch will go from 0-ohm up to some other higher number.} This means it its working.
You should lube the wires when you pull them back in to insure you don't yank your wired apart pulling them back in. Then reconnect. Clean out your ignition hole before you try to insert the ignition. You might have some broken plastic in there from the tabs when you took it apart. Make sure the front edge ground tab is still tight against the ignition hole, use tape to hold it if its loose, it'll make your alarm go nuts if you don't get it right.
If it works, the light is on the handle, not the dash.
I found this while looking around, I'm sure you guys could use it.
