Hello,
It sounds like you have a Front Electronic Module (FEM) In left "A" pillar. That is out or gotten wet. Lets remove the module and check the electrical connectors or corrosion.
Removal and Installation
Disconnect negative battery cable. Remove driver's side scuff plate. Remove driver's side kick panel. Remove instrument panel lower cover. Move carpet to access interior auxiliary junction box. Remove nuts and position interior auxiliary junction box for clearance to FEM. Remove bolts and FEM. Remove 6 FEM harness connectors. To install, reverse removal procedure.
I would try a used unit. Check out the diagrams (below). Please let us know what happens.
Cheers, Ken
