Help With Fan Pull Knob / Switch

I was able to spend some time on the wiring for my A100 and got the blower working (no heat sadly). It worked for a couple days with no problem. I could turn the knob to the right one "click" to turn it on low and then twist it to the high setting. Good times.

Well a day later it now decides to stay on all the time. It doesn't matter if the knob is turn to the off position or all the way to the high setting. I know it's not my wiring so it must be the switch behind the knob - which could be why it was disconnected in the first place.

Does anyone know what type of switch I need to purchase? I'm sure it was used in many other models and years than just my '68 A100 so I hope it isn't to big an issue to track down. Perhaps you have a working spare to sell?

As always, thanks for the help. You guys and this forum have been a great resource!

hopfully some one has one laying around, if you get no responce try reposting it during the week.

when the resistance unit on top of the heater box fails .it will make the fan motor stay on all the time.and as you have guessed, the way to make it stop is to unplug the switch.check that unit,it may be your problem
