Gentlemen: Your mission should you choose to do so, is to help Mistress figure out what has gone wrong...just got the car out of the shop for antennae mast replacement and now the interior lights won't go on when I open the driver's side door (fuse perhaps) AND my tech gave me a bottle of fuel system additive and asked me to run it through an entire tank of gas, when i punched it last night it stalled, dead in the water stall I'm talking and no it hasn't been an entire tank of gas yet....thanks for any and all help.

If the lights go on when you open the other doors then its likely that the door switch is either stuck or bad. Look at the inner door frame on the drivers door and the other doors and you'll see a black plastic rod that sticks out when the door is open. If the rod is stuck in (on the drivers side) the car thinks the door is always shut.
