I'm having a strange problem with my headlights. With the headlight combination switch in the low beam position, there is no low beam (outside light) on the driver's side. The high beam (inboard light is on). On the passenger side, both inboard and outboard lamps are on. The high beam indicator on the dash is actually on. When I flip the switch to the high beam position, both driver side lights are out. The passenger side has both lights still on, but it looks like there's a second filament that comes on in the high beam (inboard) light. The shop manual and electrical troubleshooting manual don't even mention anything about a second filament in the inboard (high beam?) light.

Any ideas ?

 

P.S. Does anyone know what role the Driver's Multiplex Control Unit plays in controling the headlights besides giving voltage to the coils of the headlight relays ?

 

sounds to me like your ballast and fuse are toasted.

 

Your high beams should not come on unless you flip the high beam switch. There is no 2nd filament in the high beam bulbs. Check to make sure they are the correct high beam bulbs.
You can try to unplug both HID bulbs & then plug them back in. Do the same with the high beams. See if that fixes it.

 

Drl?

 

No DRL.

 

ballast/inverter my friend! Be prepared to pay up......

 

yeah i had similar issue but only wid lowbeams, i ws lazy to check it out, thought it was the bulb but after a week it started working again, i believe it was the inverter because it was blinking when turn on then would go off.

 

After looking at the circuit diagram in the shop manual,the only thing it could be is the inverter unit shorted to ground. Does anyone know for sure if the inverter unit is covered under the extended warranty ? I know the HID lamp isn't but it doesn't mention the control unit.
