Did a scan today same old faults appear. Light check module fault stored? GM LED for anti theft alarm system open circuit. GM Passenger compartment sensor
1 doesn't tell the fault.
2 LED I thought that was the flashing red light under the mirror. That works and flashes.
3 where is the passenger comp' sensor

To answer my own questions, well, two of them. The LED is the light under the mirror, the passenger comp sensor is in the roof light between driver and rear passengers. So perhaps some contact spray might help?
