Model S HVAC soundcheck

[Xd85]

Got a '18 S75D with what sounds like muffling of the HVAC. Fan on 10 doesn't seem to generate as much airflow as before and seems to whine more and consume more energy. Want to make sure it's not "all in my head" before bringing it to the Service Center next week with the new "$97.50 diagnostic fee for normal noises". 48.2k miles so now or never .

Anyone in Austin area want to volunteer their similar S for comparison? PM me. Greatly appreciated!

(for those in the google group will cross-post it there so apologies in advance)

Does the sound (or airflow) change when you switch modes? For example recirculation on/off? Or if you change from floor, vents, dash?

Did try that yet. Though bioweapon defense mode only now speeds the fan to 9 for some reason.

I had reduced airflow and the AC freezing up last year. I found some of the symptoms when I tried bio-defense mode. Lots of noise, minimal airflow.

I eventually figured out that it was recirculation setting on "outside air" that caused the reduced airflow (and freezing of the inside coil as well).

They replaced one of the actuators. It was never clear to me which one, from the invoice.

I bought mine, wasn't allowed to test drive it, and as soon as I got on the highway.....the ac start making this loud noise.

So for my 2,000 mile drive home....I had to listen to this.

Yup. Same deal. Except haven’t gotten an invoice yet.

So your fixed? That’s great! Assume they didn’t charge the diagnostic fee?

Edit: oops - guess you don’t know officially until you see an invoice.

Assumed I'd get a e-invoice but no dice. Guess the diagnostic fee didn't apply because it was in-warranty, and the actuator threw an internal fault that they saw on their end. (i.e so not a 'normal noise'

You’re in Austin. Did you get the text messages during the appt? Reply and ask for an invoice.

Had no loaners (only Uber credits) but since they were pretty sure it was the actuator, I just waited at the SC for repair the next day since mobile didn't have the part and it would be days or weeks. Hence no update texts. Really no big deal i don't think
