Customer Question

I have a 2002 escalade and my secondary information center goes blank when I turn the headlights on and at night when I start the truck but it works fine when the truck is off as long as I don't put the key all the way to the start position

Can you check the charging system , when the truck is running put a voltmeter on battery are you reading 14 plus volts with all the loads on , like a/c on radio on, headlights on, flasher etc.. ?

how old is your battery ?

is the ignition key solid or loose when turn it from on to start ?

what is the mileage on the vehicle ?

Please let me know

Thank You
