    still working on the DRL's, and appreciate all the input. bulbs are new...vehicle running in drive, emerg. brake on...still no drl's. did the auto headlight system reset several times, no change....

    in the central fuse box, there is a 10 amp DRL fuse (which is new), and a large grey block just above it which is marked "DRL" on the schematic. It looks like a circuit breaker. I cannot see how to get it off, but am wondering, since it is marked on the schematic as DRL, could that be faulty, causing no DRL's?

    Guess you can tell I really want my DRL's to work.....

    IIRC, the DRLs turn off when the emergency brake is set.

    like [MENTION=57614]stchman[/MENTION] said, they turn off with the e brake on. What you are referring to is a relay. That could be your problem. They pull straight up. They are not all that easy to get out by hand. You can use a pair of pliers to wiggle it a little as you pull up. Then pull one from your headlights (one that you know works) and put in place of the DRL relay. If they work then you found your issue. I think that that relay is around $14
