1997 Lexus ES 300 6 cyl Front Wheel Drive Automatic 135000 miles
My car headlights do not turn on in park light setting or headlight on setting but when I put it in the auto setting, they all work fine. I did a continuity test on the switch and it tests OK. What else could cause the lights to not work except for in the " auto" (night sensor) mode.
Well the headlight system on today s cars is really complicated, they are controlled by relays, timers and photo cell sensors, we can start checking the relays I m going to send an a electrical schematic to your email full size and we can start following wires until we find the problem.
Sounds good to you?
I see that you re good with the multimeter probably you can find the problem with the schematic.
Let me know if you re agree with that!
BTW thanks a lot for your donation we really appreciate that!
