Thanks. Was about to give an update. I was off yesterday and didn't drive anywhere except my couple mile test drive after adjusting the steering wheel. Drove 18 miles to work today - no noise. Drove 18 miles back - no noise . . . until about 3/4 of the way back, and then it started again 😭 I immediately released the steering wheel lock and moved the steering wheel all around, but it had no effect on the clicking sound. So I locked the steering wheel back and tried turning off the AC blowers completely, but that had no effect on the noise either. Though doing that revealed another strange issue. As soon as I turned off the AC blowers, the car started to vibrate. Not violently, but enough so as to make my seat slightly uncomfortable. As soon as I turned the AC blower back on, the vibration went away. It also goes away if you leave the blower off and switch to neutral or start driving. I've never turned the blowers off before, so I can't be sure if this is something new or has been there all along. From reading online, it seems many claim this is normal (and some say they've been told this even by dealerships) - basically a slight vibration due to lowered RPMs when turning off the blower motor.
As for safety, I don't think either of these issues are safety issues in the least. I planned to take the car in to my regular mechanic in January for an annual inspection (I do the oil changes and tire rotations myself every 3k), so I'm not concerned at all to wait until then to let them have a go at it first.
