Customer Question

2002 silverado. drl not coming on and headlights are during day. replaced drl bulbs. no luck.
JA: Have you checked the fuses? Have you checked the bulbs?
Customer: new bulbs. if drl not working due to fuse or whatever do the headlights come on in place of drl. opened fuse box but unable to tell which fuse to pull. not sure if i have a tester. tried looking up schematic online without luck.
JA: What is the model of your '02 GM?
Customer: silverado extended cab 1500
JA: Are you hoping to fix this yourself? What have you tried so far?

Hello and welcome. My name is ***** ***** you for visiting the site.

The DRL's would have to be tested to see what the problem is.

If you accept my additional service request for your email address, you can give me your email in a private info box and I'll send you the test instructions in a PDF file, the file is rather large.

You will just have to accept the additional service offer and ENTER your email address in the “ENTER CONTACT INFO” section so that I can see it. Thanks

I do not have access to your email address,
