Question about 2005 Ford Focus
I notice the when I turn My headlamps on High Beam that the indicator light comes on but no High Beams!!! I have checked all relays and fuses. I also did open and close circuit test to the bulb connectors as well as the bulb its self. There was not power coming in but there was a complete circuit. Could someone tell me why this is happening and the same situation is going on with my Fog lamps. They all went out at the same time..smh

What relay's an fuse's ? open and close circuit test to the bulb connectors ??????? Voltage testing with a DVOM - digital volt ohm meter !
B+voltage going into the multifunction switch ? Fuse F2.59 7.5 amp located in the central junction box . Green with red trace goes to mulitifunction switch (high beam ) pin #6 , Pin#7 multifunction switch green with yellow trace goes to control (energize ) High beam relay . Control side high beam relay grounds at G103 ! High beam relay located in the battery junction box . Do you know how to test for B+ voltage ? Forget this open and close circuit test . Voltage drop testing is the correct way to test a electrical circuit , the circuit has to be energized .
Do you know what a wiring diagram is ? Did you view a wiring to know what you were testing ? If know ,you can't say you have a compleat circuit.

SOURCE: high beams wont turn on.
First place to start is with headlight switch. I did have a case many years ago when both high beams were blown out at once, but this is rare. When you have the headlight switch out, jump power from te low beams to the high beam contacts. If high beams come on, replace switch.

It sounds like you are confused about how your headlamp system is supposed to work. The DRL does not run on the High beam circuit, it runs on the low beam circuit. The fog lamps are supposed operate with the park lamps and also with the low beams, not the high beams. From your description, I would say that your system is operating as designed and you are having trouble telling High from Low. (Don't feel bad, that is why high beam indicators were invented in the first place.)
