Greetings:
As many of us are discovering, when one side of our turn signal lamps won't work, or some turn signal lamps won't shut off (even when car is shut off), there are no turn signal flashers to buy any more at GM, or Rock Auto, or even used on eBay, or pretty much anywhere. (ACDelco # 25716295, in the white plastic case with seven electrical pins). These are pretty much 'Non-Obtanium' at this point in time. (NOTE: Some Cadillac CTS from 2003-2007 will have the white case/seven pin flashers, but most have the black case/10 pin flashers that won't work for us.)
I have discovered this weekend that the turn signal flashers for Buick Park Avenues from 1997 to 2005 have IDENTICAL circuit boards and seven pins, only the plastic case/shell is different due to the way it fastens under the dash. (AC Delco 25684395 in a black plastic case).
So if you pull a used Buick one, or buy a new Buick one (they're readily available online from GM and many sources), all you need to do is get a tiny screwdriver, gently pry open the plastic shell, and swap shells -- then plug it into your Aurora 2001-2003 and Bob's your uncle!
Here are photos of the Aurora one (white case) compared with the Buick one (black case).
As well, here's a great two-part video on YouTube that shows how to remove the flasher from Buick Park Avenues, plus a Buick service manual diagram.

It's been pretty cold up here in Edmonton, Canada, and I was getting tired of sticking my left arm out the window for left turns! From a safety point of view, I feel way better driving now.
And thanks to Aurora Girl and the gang for all your suggestions with my earlier thread; it saved me tearing apart the steering column, as it was not the turn signal (multifunction) lever.
All the best, Greg
