low beam headlights

please help, cant figure it out. driving along at night low beams just shut off, high beams still work . then they will be on an hour later or 30 minutes, whatever., tryed the fuses moved wires around, cant find the problem. only low beams affected, both sides... help...

locate the Fuse Box in the engine compartment. After opening the panel. Then locate the Lamp Control Module, it is label with LKM on it. The LKM is the large black relay You can remove this module and take it apart. Once apart clean the relays in it with Electronic Cleaner Spray. then resoldered all of the relay connection point on the backside of the circuit board.
