I believe the lights in the rear door window switches don't come on if the 'lock' switch is switched on.. worth a check.

If the car has been standing, I would definitely consider changing the oil, then changing it again after a short distance (not sure how far.. 100 miles?) if you want the engine to be 'cleaned' effectively.

Also, be sure to change the oil while hot.

later!
