This may be a clue. Here's a diagnostic: pull one head light bulb out, so for sure it won't work. Then start your car and turn on the headlight switch. If your bulb out indicator does not come on when you go to high beams... then power is not making as far as N7 (the black box that measures current imbalance for external lights). Or, N7 is having an issue (not seated fully?). Power must pass through N7 for each circuit it measures. If N7 is missing, you also get no lights.

Experience has taught me all this... check out this related thread on how I mod'ed my headlights for more light.

OK so the historical with the bulb indicator is sometimes it is on, sometimes off. When I just went out to check on the connectors to the headlights everything looks fine. I pulled the left side connector and started the car and put the headlights on. The bulb indicator light only comes on when I pull the stalk back to flash then stays on until I turn the lights off.

The fogs work fine, aren't they supposed to go off when the stalk is pushed forward for high beams? They do not even flicker.

One thing I noticed is the right side headlight assembly was obviously hit by something and the plastic part that attaches to the front of the car is broken. Also the reflector inside the housing moves around. I will be obtaining a new one asap.

I am still stumped by leaning towards the combination switch being bad based on my continuity testing. Any other thoughts? I need to get this car inspected by the end of the month and need working high beams for that. thanks!
