SOURCE: Turning off the OnStar in a 2005 TrailBlazer

The OnStar module is under the rear seat, passenger side. You should be able to just pull the connectors out of the module. Just the rectangular ones.

The dealer is thinking about the power amplifier for the Bose radio system. That's in the fender at the right rear of the car, but that's not the issue here.

SOURCE: engine light on...onstar says its the secondary air emissions

this code is caused by the electric engine air injection pump, it is known as the "Secondary Air Injection System" and is part of the emission controls on your car, this is all to common a problem and requires the air injection pump assembly to be repalaced to correct the problem, then the code must be erased.

SOURCE: Did not pass state inspection (vehicle)

First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.

SOURCE: Change headlight on 2008 Chevy Malibu

Hi there,

Well first you can please follow the below steps -
1. Make sure the ignition key is in the off position and the headlight switch is off. Release the hood latch.
2. Open the hood and locate the top of the headlight assembly where you intend to change the headlight. If a plastic shroud is present, locate the center bolt and remove it with a ratchet and a socket. Lift the shroud out of the way to access the headlight assembly retaining brackets. Some later models may feature a snap-release shroud requiring no tools to remove.
3. Locate the brackets on the top rear of each side of the headlight assembly. Lift them all the way up to align the hole on the bottom of each bracket to the retaining tabs on the assembly.
4. Pull the assembly forward away from the Malibu, but be careful not to scratch the bumper. There are three guide pins that require unseating. The guide pins are what aim the headlights and it may take some wiggling to get the pins from their seats.
5. Support the assembly with one hand and then reach behind the unit with the other. The low beam bulb is on the outside, the high beam bulb is on the inside. You can also replace the parking light if desired. Locate the wire harness connection. Un-clip the wire harness from the back of the bulb socket. Remove the bulb by turning it counterclockwise 1/3 of a turn to align the release tabs of the ring and the assembly. Wiggle the bulb out of the assembly.
6. Place the latex gloves on your hands before opening the package of the replacement bulb. Oil in our skin can damage the glass bulbs of halogen headlights.
7. Carefully insert the new bulb into the ring and then align the tabs of the ring to the tabs of the headlight assembly. Push inward and then twist clockwise 1/3 of a turn to lock the bulb in place. Reattach the wire harness. Rest the headlight assembly inside its cavity and test the operation of the headlight before securing the headlight assembly in place. Be sure to turn the lights and ignition back off.
8. Align the three guide pins to their seats and push the assembly back into them gently until they snap into place. Replace the retaining brackets by pushing them downward to lock into place. Replace shroud, if applicable. Remove the tools and old bulb and close the hood. Post comments for further help or information......

Good Luck!!
