Rusted Ground Connectors

Rusted Ground Connectors
I have been having issues with the HVAC for about 3 years now. Replaced blower motor and resister 3 times since then. Finally raised hell with the dealership to get them to look further back than those items - spoke with the shop forman and he agreed to look at it with his tech. Turns out, there was a leak from the sunroof in 2019 that caused the ground wire for these components to rust and fail, thus causing the HVAC system to no longer work. He made mention that other ground studs were "questionable" but of course didn't tell me which ones. Does anyone know what other grounds exist under the driver-side seat that he could be referring to? Asking because I have a few other intermittent codes that I'd like to see if they are related (one of which was the heating in the seats).

Under the driver’s seat, you should check a few things. Look for the ground connections related to the seat heater, the body ground points where the seat bolts to the floor, and any electronic ground wires for the car’s electronics. Also, check the ground connections for power-adjustable seats if you have them. Make sure there’s no rust or loose wires. If you're unsure about inspecting these, a mechanic can help you out.
