In two different occasions I had to jump start the 2002 for Explorer, I did a battery load test and it was fine also check it while the vehicle was running and all the readings appeared correct and was charging ok.
My 2002 Ford Explorer lxt, the door ajar light stays on and the dome light will stay on. Every once and a while the alarm will sound for no reason. This is a safety concern cause while driving at night and having the dome light turn on hinders your vision and could cause a traffic crash. Having the light stay on after you get out also drains the battery and causes problems when you go to start it up.
