Headlights not working and dash lights go dim

The car listed above is a six cylinder, front wheel drive, automatic.

I am having problems with my headlights. The other night they were working perfectly. I parked the car and shut it off. When I went to start it up the lights didn't turn on as they usually do. When I manually attempted to pull the switch so that the lights would come on, nothing happened. The only way for the headlamps to come on is the pull the lever on the steering column in which the high beams came on, however would not stay on. All other light work, fog, interior, turn signals, brakes, etc. Just not the high/low beams. And this vehicle does have a day/night sensor that automatically turns on the lights.

I've checked my fuses, relays, bulbs, connections, and other common problems. The last thing I think it could be would be the light switch on the steering column. Any feedback/troubleshooting would be a great help.

My headlights wont come on all others do turn signals won't work pull the hi beam lever they come on but go off as soon as you let go of lever. Used my scanner and there was no codes.

I have checked both and there good any other ideals

I checked all of connections they good but however I was able to run a ( (GROUND) not a (HOT WIRE) and the lights came on but only the (L/BEAMS)not the(H/BEAMS) and the (turn signals) STILL don't work but the (HAZARD LIGHTS) work. I was told it could be the (B.C.M) body control module.
I WILL WAIT for your response now thank you

The turn signals work part of the time now the headlights don't work now.

My headlights do not come on when I pull the switch out. I have parking lights and fog lights but no headlights. If I put the high beams on they work. What could this be?

My high beams lamps aren't working properly when I pull the lever to turn them on. I can see the high beam icon in the instrument panel and I can see the high beam lamps come on, but they do not remain on after I release the lever. Do this mean the lever is bad or what? Are these difficult to replace? Are they expensive? This vehicle only has 78,000 miles on it.

Thanks

Replaced heads and get in to start. Starts up many many times no problem. Get in a few days later to finish up and tie up loose ends and try to start. No power anywhere except check engine light and information center with mpg. Info on roof is the only thing that is working in whole car. No headlights no dash lights no power anywhere except cell and info center. Any ideas? I am going to get a netspend card so I can give some money for your help.

Interesting problem. Id start with battery voltage. Then if that's ok, look at the side terminal battery cables. Take the black and red rubber boots back off the cable ends as they can be multi layered and build up corrosion between the layers. Also check for wire damage in the air box behind the air filter. Rodents LOVE to get in there and chew on all the little wires. If that's all good turn the key on and start wiggling wires watching for signs of life as you go.
