Just checking with anyone who has a 66' Canso, this is not an SD car. The question is we are putting my dash back together and we're looking at getting the dash lights to dim on the headlight switch, it's been so long that I can't recall if they did. The headlight switch does have the rheostat so I assumed it did. I have replaced the headlight switch since I can't get it to work, we have gone through the original service manual and from what we can see laid out in the wiring, it doesn't appear that it does dim. We've spoken to a contact that said that it should, we just are struggling to see how after disecting the service schematic. If someone has one of these cars and could confirm, we'd be greatful.
Thanks for this...I'm still investigating this and will look for a jumped wire. I have spoken to a few key sources and gotten different answers from both of them. One of them claims like you that yes they dim, the other is a Nova guru from the US and claims they did not. Still working through this... I trust yours does dim as you stated. Thanks again.
Jim, I'm shocked that since this topic is about "dim" you haven't made some sort of comment about Doug...
Carl don't make me go to JohnneeD's side against you?

Do you have an owner's manual for your car? I don't have one for a 66 Nova or Acadian but my 66 full size Pontiac owner's manual explains about increasing or decreasing instrument panel light density by rotating the control knob. I know the Acadian owner's manual will say the same thing.

the 1966 Acadian shop manual show a rheostat on the light switch. in all the acadians ive delt with over a forty five years ive been involved with them , all had dimmers
Great idea Carl, never thought of that as I didn't even think I still had it and voila yes I did and yes it confirmed the following from it:
"instrument panel lights can be increased or decreased in intensity, or turned off, by rotating the control knob. To operate dome light, turn switch knob fully counterclockwise.
My current switch doen't allow it do so, so I ordered the AC Delco part # that I sourced online, it doesn't allow it, so I will continue to work through the wiring to see what else it could be.
If the wiring at the switch all looks normal, it seems like it must be that the wire for the dash lights is in the wrong port in the connector at the switch.
Man, what a stumper. And you know it's gonna be something simple!

Replaced the switch, went through the entire harness and the way its laid out in the schematic, it doesn't look like it ever had the ability to dim....I know many of you replied that it certainly does....I had one Nova guru out of the US tell me they don't.My only thoughts were is it possible some basic models such as mine didn't? Like I said, wot of time went into trying to solve it and we had no luck so I dropped it for now to move onto other things in putting the car back together. I will advise if I ever get it going.
