HI all
Got my 2009 Suburban LTZ, DRL were not working. both Bulbs are OK, got them out and checked them indivudaly. Fuse under hood is also OK.
I need your help in directing me to what other parts should be inspected and where these parts are.
I have searched for a diagram that can help but no success.
appreciate if you guys can help.
regards
Akram

might have been reprogrammed for them not to come on. there is a sticky at the top of the page to this.

Akram welcome to the forum...

Do your headlights and other exterior lights all work correctly?
Is the headlight switch in the "auto" mode?
Is the solar sensor on the dash covered up?

thank you both for the feedback.
iam not sure if they were programmed for this, i tend not to beleive so as people here will not go through trouble to do so, however it might be valid i do not know since i got the vehicle they n ever worked.
as for other lights every thing is working fine daya and night. i tried covering the sensor during tghe day main lights came on.
i treid looking for thye wiring diagrams and the location of parts to check but no success.
