I have a 2002 is300, problem is my headlights.
It started a day ago, shut my car off and headlights on the multi switch. Came our and they were flicking off and on then stayed on, with the key out of the ignition. I pulled the battery cable so I didn't come out from work to a dead battery. Drove home without head lights got home and the lights stayed on still. So I checked the relay and fuses (simple ones), all still good. Talked to a buddy, searched around some other forums, started power probing back. The only thing we can kinda figure out is that the drl main module (under the dash) or the ignition. Any help?
