Part of that is true but it's also a cover your rear situation. If they found a used part and installed it and it burnt out in a week it would make for one ugly situation. Worse yet, installed used part and it's dead on arrival. Someone needs to pay the tech for their time.
If however the customer supplies the part knowing and acknowledging to the facility it's used, they understand no warranty, then the facility is off the hook as far as any kind of warranty then they shouldn't have a problem with maybe bumping up the labor a bit and instilling the used part. You bump up the labor a bit to cover the profit you're losing on the sale of the part. It's an option I'd rarely offer as I hated installing used parts but there are times like this where there isn't a good alternative.
It's just another way to look at why a place might not want to go with used.
BTW I understand the problem as I wanted to upgrade my Thunderbird to LEDs only to find out I couldn't since it doesn't have a separate flasher. It's part of something else and being a '95 I always worry that's one of the things that is going to fail and be a real pain to try and locate or fabricate.
On a 2013 I would think they'd use more off the shelf stuff that's already proven tech rather than spend time and money redesigning something like a turn signal flasher circuit and windshield wiper circuit and then combining them.
