2001 Marquis electrical problem
 

Simultaneously the following lost function:
1. interior dome light
2. dash digital clock
3. cigarette lighter (need it to recharge cell phone)
4. power door lock button on door

I got the fuse diagram and checked all the fuses pertaining but none of the fuses were blown. So what can it be?

it sounds like it has to be a fuse. i think all of them components run on the same fuse.

I would suggest you to get your car checked by a technician.he'll be able to tell you whats wrong with the car.
