Help please- Need a Auto Electrician & Mechanic '01 Mustang Cobra Vert.

[OzCobra01]

Hi, I'm new to the forum and hope this inquiry is ok? I'm looking for a recommended mechanic and Auto Electrician.
Passenger Airbag light flashing 33. "Open circuit.......". Also heater knob won't fully turn. Etc.
I've managed to maintain the car since Ford stopped looking after servicing these. (The team at Ford, Boundary road Braeside were fantastic).
Your experience and guidance would be appreciated.
