On my '67 Crown hardtop, the power windows work without the ignition being turned on.
Should you end up needing to replace your turn signal switch, you can get a good quality new one from these folks: http://www.shee-mar.com/ They can sell you a cancel cam too -- which you might as well replace while you're at it, whether it needs it (yet!) or not.
I own a '67 CC & have traced my inoperative brake lights to the turn signal switch in the tilt column. (&^^*%#%). However, I've run across one more item that could possibly change that theory.
If memory serves (after many years), I seem to recall that the power windows work only with the ign/acc "on". Do the power windows on a '67 work directly from the battery or only when the "acc" or ignition is on? (I know that the '57s worked off the battery, but did the '67s?)
My windows activiate regardless of the ignition, so I'm wondering if the wiring could have been 'boogered' with...changing the diagnosis altogether?
Please advise...thanks!
