lebaron hideaway headlights

the year is around 1990 ish, 88, 89, 90, i dunno lol. but the hideaways are inop. they are open, so the headlights can be used fine, i figure its something in the vacuum system, it almost always is. my question is, though, on this car, how difficult is it to work on the headlights? can i access it with the hood open, or am i gonna need to remove a bunch of stuff off of the car. any help would be much appreciated, thanks in advance!
