Question

Security light on dash will come on randomly after driving, normally then traction light, then brake, ABS, fuel gauge will go to 0, A/C and radio will turn on and off. Radio controls on steering wheel will not work if security light is on. It started randomly and is not almost alway on. GM dealer checked codes (car ran normal when I took it). It read many error codes. They suspected bad wire/communication between modules or bad module. They said they could start replacing modules but it would be very expensive. I have checked fuse blocks and all plugs that I can find. All are clean and good condition. I took it to Persicion Tune yesterday. They recommend replacing switch for $350. I do not think if is switch. Help! Johnny
