I just changed the driver's side headlamp on my 1998 Grand Caravan. The plug in the wheel well didn't give me access to the headlamp, just to the signal light. Had to remove the entire headlight housing (removed one screw on top and three nuts from the back), and then pull out the plug, twist out the protective casing that was around the plug and that sealed the bulb, and then pull out the bulb itself and replace. The fuse box made this work almost impossible - very little room to work with. Overall took 40 minutes.
