Fuses - No Fuse. I THINK it is powered by the Body Control Module and you can't remove that or disconnect power..

OnStar doesn't have a named fuse. The Radio and Infotainment System are two separate fuses. You need a good auto-electrician to find the source of the parasitic draw, not find a way around it. You can test it yourself. Put an ammeter on the battery and pull one fuse at a time while someone observes the ammeter. Pulling one fuse will be the cause of the drain and show a drop in discharge. That is the circuit where the issue it. There is always a small amount of drain from the ECM, clock, security system etc.

No that is a dealer only job as special equipment is required.

Should have a separate fuse for the Onstar. Just remove it and see if that helps.

That red light is on many vehicles and does not drain a battery that fast. You probably have another draw on the system. I recently had a car that the battery would go down in a few days, found out it was coming from the Onstar system malfunctioning.

check fuses and relays --try boosting the car battery may be able to turn on lights but not able to start vehicle their is a tsb technician ser vice bulletin on the 07 for power drain from the onstar module if starts have battery and alternator tested most auto stores offer this service for free -no start check key and ignition switch for wear worn key or switch will turn but not start vehicle and also check starter but the occasional click points toward a dead battery COMMUNICATION PROVIDES INFORMATION TO HELP THE DEALERSHIP TECHNICIANS PERFORM A PARASITIC DRAIN TEST FOR THE ONSTAR MODULE.

Camshaft Position Sensor Replacement (5.0L, 5.7L)

Removal Procedure

Caution: Refer to

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

For Vehicles equipped with OnStar® (UE1) with Back Up Battery:

The Back Up Battery is a redundant power supply to allow limited OnStar® functionality in the event of a main vehicle battery power disruption to the VCIM (OnStar®module). Do not disconnect the main vehicle battery or remove the OnStar® fuse with the ignition key in any position other than OFF. Retained accessory power (RAP) should be allowed to time out or be disabled (simply opening the driver door should disable RAP) before disconnecting power. Disconnecting power to the OnStar® module in any way while the ignition is On or with RAP activated may cause activation of the OnStar® Back-Up Battery (BUB) system and will discharge and permanently damage the back-up battery. Once the Back-Up Battery is activated it will stay on until it has completely discharged. The BUB is not rechargeable and once activated the BUB must be replaced.



1. Disconnect the negative battery cable.



2. Disconnect the spark plug wires and ignition coil wire from the distributor.


3. Disconnect the CMP sensor harness connector from the distributor.



4. Remove the distributor cap screws.



5. Remove the distributor cap.



6. Remove the rotor screws.



7. Remove the rotor.
   


8. Remove the CMP sensor screws.



9. Align the square slot in the reluctor wheel with the CMP sensor.



10. Remove the CMP sensor.
    

Installation Procedure

Important: Do not use the old cap screws, CMP sensor screws, or rotor screws. Use replacement screws that have been coated with a thread locking compound. Precoated replacement cap and CMP sensor screws can be acquired using P/N 10475922 (pkg of 10 screws). Precoated replacement rotor screws can be acquired using P/N 10475924 (pkg of 10 screws).

1. Align the square slot in the reluctor wheel with the CMP sensor.



2. Insert the CMP sensor through the reluctor wheel slot.

Notice: Refer to Fastener Notice in Cautions and Notices.




3. Install new CMP sensor mounting screws.
   
   Tighten:
   
   Tighten the fasteners to 1.6-2.8 [n-m] (14-25 lb in).
   

Important: The locating tabs on the rotor are necessary for correct alignment of the rotor. If the tabs are missing or damaged, replace the rotor.



4. Install the rotor onto the reluctor wheel.



5. Install new rotor fasteners.
   
   Tighten:
   
   Tighten the screws to 1.5-2.4 [n-m] (13-22 lb in)
   


6. Install the distributor cap.



7. Install new distributor cap screws.
   
   Tighten:
   
   Tighten the screws to 1.8-3.0 [n-m] (16-26 lb in)
   


8. Connect the CMP sensor harness connector.


9. Connect the spark plug wires and ignition coil wire.



10. Connect the negative battery cable.

Usually if battery is good. Its usually a parasitic drain. You can use a standard multimeter, and put across each fuse top. Two little tips. If you see a voltage even a little bit. That's a drain. Find what fuse go's too. And diagnose.

Okay, i will start by saying this is a job that should only be done by someone who works on cars, first thing first is if your car has onstar you must disable the back up onstar battery, if power is removed the back battery will be turned on and run until it drains out and then will need to be replaced , does not matter if you reconnect battery quickly. so first make sure key is off and out of ignition next open driver door , leave open , dissconnect battery, this way the back onstar battery is not turned on.

With that done you will next remove the belt then remove the front alternator bolt.then you will need to drain and remove the radiator,next you will need to raise and support car, remove front splash sheild, next loosen rear alternator bracket from engine.

Remove top bolt,front lower mounting bolt and lower rear mounting bolt, remove upper rear mounting bolt.
Remove air duct from rear of alternator. Disconnect wiring from alternator. next remove front alternator/ A/C bracket. rotate alternator and remove. To install reverse procedure .
GOOD DAY.
