Expert:  Tracer3 replied 6 months ago.

ok, now, I must know if you have the auto off headlights or the non auto off hedlaights

Customer: replied 6 months ago.
Not sure - they do not come on automatically
Expert:  Tracer3 replied 6 months ago.

sorry, not the question, If lights on, do they turn off automatically when you shut the vehicle off

Customer: replied 6 months ago.
I cannot remember, I always turn them off and cannot remember if I ever forgot to what happened
Customer: replied 6 months ago.

WHY IS THIS NOT WORKING
Customer: replied 6 months ago.
I just refreshed page and now see all the things I said
Expert:  Tracer3 replied 6 months ago.

all the replies are getting to me. you are rushing the post, I have to pull up diagrams, type and reply and by hitting send over and over the post is filling up and hard to work with you. maybe best I opt out and open the post to another expert. One should be along soon to help

Customer: replied 6 months ago.
Randall, I am sorry. In the beginning I could see my response as soon as I typed it. Then all of a sudden I could not. I did not know they were going through.
Expert:  GDibs replied 6 months ago.

I might be able to help. One thing that I can add is the fact that your high beams work tells me that the relays and fuses are good. The difference between high beam ad low beam is controlled by the headlight switch an which circuit it grounds, either high bean or low beam. If you could access the headlight switch connector I could give you some tests to try. I am assuming this is a base model Odyssey LX not an Ex or EX-L. There are some differences between the two.

OK - I was having issues and now switched to internet explorer and it is working better.
Customer: replied 6 months ago.
Well that stinks - two mechanics have bailed on me now. The issue was my firefox browser.
Customer: replied 6 months ago.
I think it is an EXL. Leather heated seats, power doors, but no sunroof, dvd, or navigation.

Expert:  GDibs replied 6 months ago.

weird, not sure why it doubled up on that post

Expert:  GDibs replied 6 months ago.

If we go with it being an EXL then lets see what tests I can give you

Customer: replied 6 months ago.
Ok. We are out shopping now so it will be awhile before a can do this. Thanks for coming back.
Expert:  GDibs replied 6 months ago.

I am like you and kinda new to the system. Most people do not respond to me right away and we end up going back and forth for a 1/2 day or more. I was away from my computer fr a couple hours this morning.

Expert:  GDibs replied 6 months ago.

I am not sure what your capabilities are but if you can manage to get the covers off of the steering column that surround your combination switch I can give you a test that should determine if you have a bad combination switch.

Customer: replied 6 months ago.
Fairly handy. I'll see if I can do it when I get back
Expert:  GDibs replied 6 months ago.

ok , if you manage to find the connector of the combination switch there should be 2 white/red wires in the connector. The light switch should ground those wires to turn on the low beam lights. If you could manage to back probe those wires with a pin or paper clip or something like that, then turn the light switch on and ground either of those wires and see if the low beam bulb lights up. One controls the left and the other is for the right. Hope this is helpful.

Expert:  GDibs replied 6 months ago.

You would need a jumper wire to connect the pin or paper clip to ground.
