Personally, I would suspect the DRL relay as being bad, check it with an ohm meter.

The left lamps use the relay to get a ground connection. According to the schematics in my Chilton book, When DRL is engaged +13.8 comes down the DRL fuse, into the DRL relay and goes through both the left and the right lamps in series, so each is getting half of 13.8V in order to run the lamps in an undervolt condition.

With DRL off the left side is grounded through the relay, allowing full brightness to the left lamp. If the contacts in the relay are bad this will result in the left side not functioning at all. The right side is already grounded so this allows it to function without the DRL relay.

TheDesertFox: I believe you are having trouble distiguishing fuses, relays and diodes. Removing DRL fuse 15 which is 10 amp and should be blue should disable DRL, but the DRL relay, which is the square thing I believe you are refuring to must be left in place.

Reportedly some models had a diode in the fuse block that you remove and it disables the DRL but I do not have one of these for some reason. Diodes are usually round cylanders, black in color and will always have a stripe on one end or the other denoteing polarity.
