Hello, When looking down at mass air flow you will see A, B, and C also the release on the connector will be at the opposite or bottom of the MAF sensor when reading A, B, and C. OK!

Please note this is correct for all GM, PONTIAC, OLDSMOBILE, CHEVRELET, and CADILLAC.

Unplug the connector, under the dash and remove it from the steering column. It is very complex procedure if you never play with SRS system As far as I can tell the noise you can hear is the

You have to track down what is draining the battery. If you don't then you will have to disconnect the battery every time you turn the car off. Sometimes finding the issue can be tricky. You can try looking at your fuse box and start pulling fuses for non essential things like .... tell radio and see is it still drains or use the shotgun approach and pull about half the fuses then wait with car off and re-install them and see if battery us dead, if it is dead then pull half of the ones you pulled, etc...etc...etc....till you find the one causing the problem...use this method as an isolation method if you have no other option ....

When the headlights go out, check for power to the low beams on the orange (RightT) and orange/black (left). If you're getting power, then the problem is on the switching/ground side of the circuit. The body control module uses the ambient light sensor as an input and the headlight switch. If the light sensor see dark, the BCM provides ground to the control coil in the headlight relay. When the control coil is energized, it closes contacts that provide the ground path to the headlights. Since this is intermittent, I suggest tapping on the headlight relay with a screwdriver handle when the lights go out. It's located behind the glove box. Or, try swapping the relay with a different one and see if that solves the problem
