2002 Bonneville-electrical problem

I have a 2002 Bonneville. Both the windows on the passenger side don't work. Does each window have a separate fuse ? I also have a problem with the headlights at night. When the car is in park...and the automatic lights are on...the headlights flash on and off...as soon as you put the car in D or R...they work just fine. Any help would be great. Thanks !

I would check the fuses first..I don't think they run on seperate fuses..If not I know these cars are noted for their window regulator problems..As for the headlights..I think that may be a sensor problem...

There is a 30A breaker in the rear fuse block that supplies power to all the power windows. There is a 10A fuse in the rear fuse block for each of the four door control modules. The control module controls all functions for that door regarding switching power & ground. All comms are via serial buses. It would be unusual to have both passenger side doors inoperable. Quick question, do the power mirror & power door locks operate?
