It sounds like the voltage regulator is malfunctioned but hasn't went completely bad. It has a built in regulator unlike the old cars. Also check all your connections from the battery to the starter solenoid and back down to the starter.

Do This - Reprogram the HVAC control module.
Don't Do This - Do not replace the coolant level sensor, HVAC control module or radiator surge tank.


A revised calibration has been developed to address this condition.

How do i clear the change engine oil soon message. It's a 2007 silverado.


The "Change Oil" message displayed on your Chevrolet Silverado's gauge cluster is part of the Oil Life Monitoring System, standard on many GM (General Motors) vehicles. The message appears when it's time for an oil-change; the interval is based on your driving habits (for example, it may appear more frequently if you engage in a lot of stop-and-go traffic). Once you change your Chevy's oil, the message will not disappear; the system must be reset. The process is a bit different between Chevy Silverado models.

    2007 to 2010 Chevrolet Silverado
  1. Step 1 Insert your key and turn the ignition to position "C" (Run/On) without starting the engine.
  2. Step 2 Press the second button from the top on your information center (next to the steering column, car symbol) until "Oil Life" displays on your odometer cluster.
  3. Step 3 Press and hold the "Reset" button on your information center (check mark symbol) until the "Oil Life" display changes to 100 percent.
  4. Step 4 Turn your ignition to position "A" (Lock/Off).
  5. 2002 to 2006 Chevrolet Silverado
  6. Step 1 Insert your key into the ignition, and turn it to position "A" (Run/On) without cranking the engine.
  7. Step 2 Depress the gas pedal three times within five seconds. The "Change Oil" message will begin to flash.
  8. Step 3 Turn the ignition to position "A" (Lock/Off) once the light stops flashing (about 10 seconds).

My instrument panel is doing the exact same thing. It started today. I almost think it may be a loose cable to the computer that drives the lights. Did you ever resolve your issue?

Battery Emblem shows on message center


Could be a Loose Battery cable. or even the terminal of the Battery where the Cable screws in could have come loose. If these are OK then Try Removing the ECM Fuse on the Fuse Panel for 2 or 3 Minutes to Reset the Computer. Let me know what U get.
