Been meaning do this too..... oh well, wife and kids come first...
took it to the dealer this morning and requested they reprogram the hvac control. got it back a couple hours later and my b0168 dtc is gone and rear heat works properly. so in my case the hvac unit I replaced this summer did not have the correct software and was giving an error for a "rear temp sensor 2" that my vehicle does not have and needed to be programmed out.
What did they charge?
$123 I could have probably installed the tisweb or whatever it is on a laptop and paid the fee to get the software myself for probably half that cost but that's probably a time consuming adventure of its own so I just decided it would be easier for them to do and if they brick it then it's on them. the exterior temp doesn't show on the hvac control anymore like it did (just in the dic) that was probably the first sign it wasn't quiet right because nobody else's does either.
I tried installing that tisweb crap on my laptop and it was a huge pia, compatibility mode, software key, blah blah then I would have to buy a license and deal with installing it...no thanks. Maybe if I was working on cars for a living.
ya I kinda figured it would be a pia so I didn't even bother I had already done all the troubleshooting anyway so I was 99% sure it was just software, I have better things to do than screw around trying to make software work for 3-4 hours or more lol, quick and relatively painless.

I'm looking at it as you saving some diagnostics charges as well as gaining a deeper understanding of these things. Good job.
My power steering saga
PS pump whining... buy rebuild kit
Pull out old pump and tear it down...
Rebuild power stee... Rebuild MOST of PS pump after completely fudging the shaft bushing...
Reinstall moderately repaired PS pump because the thing needs to drive the next day...
Watch everyone in the school parking lot stare as you drop off the kids...
Buy reman PS pump.
