2)My front power seat switches on both driver and passenger sides only operate when the lower of the two door contact pins are extended(door open position). When the pin is compressed by the door being closed--- no switch functions.
3)I have a high pitched, and very intermittent warning buzzer which sounds under the driver side dash. If I rock back very hard against the driver side seat back and roll around on the seat itself for awhile(this is almost sounding pornographic!) I can sometimes get the buzzer to stop---but only so infrequently that I can't really attribute the silencing of the buzzer to the action taken.

1) It's got some fairly complicated circuitry for the headlamps and it all goes via the exterior lamp failure monitoring unit. This device is inside the fuse box and all power to and from the headlights/taillights/markers goes through this device. I'd bet that the problem originates in this unit.
2) The seats operate when the door is open. This is normal. If you close the door, the keyswitch needs to be in the #2 position to operate the seats.
3) How long does the buzzer operate? The seat belt buzzer operates for about 10 seconds after you turn the key to the #2 position. You can silence the buzzer by pulling the connector (a single two wire connector........all by iteself) underneath the driver's seat.
