Light switch disassembly
My 31 Roadster has something shorted out inside the light switch. I'm wondering 1: how to get the switch plates out into the open. Do I push on the horn contact? 2: is there more than one switch? and 3: Is the plate(s) keyed so that it will only fit one way? Thanks. I feel so dumb.

Re: Light switch disassembly
There is a pesky little "C" clip on the bottom of the horn rod. The process is to first place a thin piece of wood through the steering wheel to hold the horn botton down so the rod doesn't come up when you remove the clip. Once that is in, remove the cover from the switch and push the contact plate up till the clip is accessable. Remove it and it all comes apart. I'm sure someone will have a diagram for you - or, if you don't have it, buy Les Andrews' red book.

Re: Light switch disassembly
Sorry, guess I wasn't clear. I'm not trying to remove the horn rod. I'm trying to disassemble the light switch.

Re: Light switch disassembly
The light switch "bulb" is held to the bottom of the steering column gearbox by a "bail." This can be unhooked causing the entire bulb and wires to separate from the column.
The bulb in made in two pieces - the upper part which plugs into the bottom of the column, and the lower part where the wires enter. The bulbs halves "separate" by turning each opposing (sort of like the plastic easter eggs) and inside you'll find the "wiper" in the upper half and the switch plate in the lower half. The switch plate is held only by the presence of the upper half: with out the upper, the switch plates can be pushed up and out of the lower half by grasping the wires. The switch plates are soldered to the wiring harness. Normal removal is to "demount" the entire wiring harness and snake all this back through the hole in the lower bulb half. It is possible to "unsolder" the wiring harness from the switch plate, but its a remedy probably more challenging than dealing with it by a normal removal. Good luck with this. Hope you find all as I describe. Joe K
