Welcome to just answer.com. I'm here to help you and your 100% satisfaction is my goal.This is very often caused by either faulty relay or a faulty resistor in the day and time running lights . Here's a couple of tests to do let me know what you find , I'll be with you as long as it takes to solve your problem so reply back to me right here . Thank you very much, it's a pleasure working with you ,Locate the Daytime Running Lights relay in the Underhood Electrical Center . Remove the relay. Identify pins 87 and 30. Using a suitable jumper short the corresponding terminal in the UHEC. Check for the DRL to illuminate. If they do not, locate and disconnect the DRL resistor mounted to the outside frame rail, forward of the left front tire and wheel assembly. Short the Gray wire to the Black wire. If the DRL illuminates, reinstall the relay. Replace the resistor and clear the code.

Located resistor, shorted the wire. The day time light indicator or drl are not working.
