FWIW I tried coding it out which fixed the rapid flashing issue, but then I went around the car and the left rear turn signal was intermittently out (sometimes it'd kick on after a few seconds and sometimes not, sometimes only barely lit up).

Not a big deal as I need to get the car in for service anyway, but just putting it out there in case there are any folks who assumed it's just a coding thing when really there might be a bigger issue.

Glad I caught it because I've checked the turn signals when rapidly flashing (and not) before and it seemed to be lighting up normally, so I wonder if there's a bunch of other folks out there thinking they've fixed the issue when their signal is pretty much out...

I ended up giving it the fonz and it's working now.
