Climate Control / Airbag / Radar / Parking Assist NOT WORKING (1 Viewer)

These seem like disparate systems, so I'd be digging through the EWD looking for points of commonality. Things like grounds, body control ECU, junction connectors, fuses, that sort of thing. Once you determine that, I'd verify relevant components are getting power and ground at the plug, check fuses, look for any signs of corrosion in pins, check that all connectors are all still firmly seated. A bad ground alone has been known to wreak mass havoc...

Thanks for the input. They tested all the fuses and relays. All good. I forwarded your (and other's) suggestions to look at grounds and the firewall passthrough. Waiting to hear back.
