Headlight Adjustment Help?? Backed out too far

I was trying to adjust the height of my 2001 Mustang and adjusted it up to far. I thought i was going down.

Now the little white thing that goes in and out where you adjust the headlight is stuck out. Which means the headlight is pointing all teh way up in the air.

I cannot use the adjustment screw to make it go back in.

Any ideas how to get the little white thing to go back in so i can adjust the headlight back down.

FYI the phillips screw just spins and will not catch it.

Please help me
