Pulsating inboard lights
Hey guy's recently i have noticed that when starting truck in the morning the lights inside mainly on my electronic climate control screen and in dash lightly pulsating dimmer then bright.....i was thinking glow plugs but it hasn't been that cold...low's around 60...but could it just be the glow plugs first thing in the morning? even at those temps....?

3 years (almost on the dot) for my batteries. If you are under 36k miles (and less than 3 yrs old) the dealership will replace your batteries - BUT only if you bring your vehicle to the dealership with the batteries in the vehicle.
I would advise you to also get your alternator checked.

Doesn't change my opinion! If you keep starting it this way, you will be buying a new FICM too.

The alternator is ONLY covered by the 3 yr / 36k warranty.
There is no way to tell how much stress and strain the FICM circuit board can handle.
Having the batteries individually load tested is free and easy. Testing the alternator at the auto parts store is also free and easy. Do yourself a big favor and get these things done soon.
