either a blown fuse or bad headlight switch
nope! I've checked.
Take off the steering wheel. There is a turn signal bar that you have to clean the pins and bend them out to put more pressure on the contacts. Then put it back together.
checked fuses, or checked for voltage to interior light socket?
If the headlights flash on and off, there may be a problem with the bulbs or fuses. There may also be a problem with the battery connections or wiring.
push the parking brake ,before starting the engine
That's a very good question, please Can someone answer it or is it that uncommon of a thing. 96Buick regal custom 3.1 Headlights are off when you have parking brake on and turn ignition over, but after you lift parking brake the only way to turn off the lights is to turn off the ignition fully.
Check the dimmer switch
hi
Possibly in the Parts department of a Buick dealership or at a large auto parts store.
Could be the resonator
the dash and radio lights are supposed to dim when the headlights come on. Make sure you have the brightness of the dash lights turned up as much as possible.
I have checked the gas cap and pressed the reset button
