Re: Head lighte only ON when pull up on High/Low lever
Coulod be a bad headlight fuse or relay. it is also possible that your regular headlight filaments are burned out, but the high beams are still good, but it would be unlikely for them both to burn at the same time.

The Buick Century is equipped with a
multi-switch. This switch is an all in one switch that controls your
cruise control, windshield wipers and turn signals in one switch. This
switch also controls dimming and brightening of your headlights. The
dimmer switch is simple to replace, and all you need is a phillips head
screwdriver to complete the task.
Removing the Steering Column Shroud
Removing the dimmer switch starts at the steeringcolumn.
To plan this task out, access the steering column by removing the
screws holding the steering column shroud in place. This will expose the
turn signal lever. Remove the lever by twisting it forward, and pulling
it out of the switch.
Removing the Dimmer Switch
The switch is held on by two
screws and a wiring harness. The wiring harness can be removed by prying
up on the locking tabs and pulling the connector out of the socket. The
two screws can be removed with a phillips head screwdriver. The switch
will slide out. To install a dimmer switch, be sure to repeat these
steps in reverse order.
absolutely not the timing belt has no connection to headlights,first locate and check any headlamp related fuses located in either fuse box underhood or in dash area if no lights on high or low beam may pull headlight bulbs and check unlikely both go bad @ once this may end up being multifunction switch on steering column your turn signal lever is what you pull back on to switch rom high beam to low beam correct? if so this switch can cause your problem
Sounds like the plastic tab that your High/low beam lever (on the steering column) switches has slipped out or broken and was displaced by the column movement. The lever assembly will have to be pulled, inspected, and (probably) replaced.
Considering all you have done, that is the only thing left (except a broken or shorted wire that connects to the suspect lever assembly - but unlikely).
Let us know what you find... please! -Jim
On the steering column. There is the yoke to twist to turn on the head lights. Well on that same yoke, underneath the buttom side facing the dash, look for a little lever, or on some a tiny sliter. Tun on the headlights first, then move the lever. This will turn on the fpg lamps. They will not come on without the headlights on.
pull on the signal lever toward you (ceter position). the signal lever controls the head lights either high beam or low beam. if you pull on the signal lever toward you again, you will have high beam temporarily. and if you push the signal lever towards the front, you will have the high beam locked.
You probably need a new combination switch, located in the steering column, integrated into the control lever for lights. Remove airbag (if you have one) and then pull off steering wheel to access switches. We bought ours at you-pull junkyard, but I believe AutoZone also carries them for far less than dealer price.
Some time back I found some data on a similar website suggesting that the Day Light Running circuit board, just under the steering column, developed cracks in some of the soldered joints. Your high beams should also be affected with loss of day light running lights. Resoldering repaired the continuity of the circuits. Ours is now working quite reliably. Some of the defective areas developed slight brownish discoloration, that's how I was told to recognise the areas to be resoldered. Hope this will help you solve your problem.
