intermittent problems with blinkers, cruise,wipers. Changed the switch assembly and the drl and low beams did not come on.All of the above work better than ever. High beams work. Changed the drl module, with no change.

Thank you for the suggestion, but there is no relay in that fuse box for the drl/lowbeam. Is ther another location for this relay?

check fuse 4 and 15 in ip fuse box as those deal directly with headlights and drl. I'm sending a pic of where relay for drl is. there also is a diode that may have gone bad and not sending power to relay. it is the orange wire going to relay. this relay also sends power to low beam headlights.
