Headlight out of alingment...

Both headlights on my 95 Grand Caravan are facing down and inward making it dificult to see at night. I can't see/find the usual adjustment screws that you see in most cars to correct/aling the headlight units. Can someone point me to the right direction? Anyone has any pictures or ilustrations? My Chiltons Book don't have any!

Probably the best thing to do is just take it in. there you'll have it done correctly. Tried adjusting it on my truck one time and totally screwed it up.

bump...
has anyone come up across anything (links, info, etc.)?
