The DRLs share the highbeam bulbs on the stock FRS headlights. They should go off when your headlights are turned on and are dimmed by a relay that routes the power through a resistor that reduces the current so that they light dim. The resistor is on the passenger side by the back of the turn signal in the front (taking the bumper off is really helpful in locating it). If your driver's side is not dimming and the passenger side is with your headlights off then you could have a problem with a faulty resistor that is not down stepping the driver's side current. Also could be that they screwed up by disconnecting and not resetting something they should have. I would check that first before looking at the resistor as the problem. Should be covered by your warranty.
