Asked Claude for cutting down research time:

- the button is integrated in the A/C dashboard? Everything needs to be replaced. Part cost: 250-600€ depending on car model and brand

- some dashboards can be stupid annoying to disassemble (Claude mentions VW, BMW, ...), 2-3h work at the dealer: 240-540€

- diagnostic fee they'll charge before they touch anything: 80-150€

Total cost: 550-1300€

"...With a premium German brand and a complex dash, breaking €1,000 for what is functionally a single button is entirely realistic..."

Yes, you can save money if you go used/aftermarket and DIY, but the same applies to Tesla.

Tesla:

- 1300€ touchscreen (e.g. for my old M3 2019): https://epc.tesla.com/it-IT/catalogs/34f82bd6-90fb-417c-8a06...

- probably 45m tops disassembly and reassembly: https://service.tesla.com/docs/ModelY/ServiceManual/en-us/GU...

Lots of used parts available, since they have the same parts for 10+y now.
