I took apart my mode selector switch because it wasnt shifting vacuum. However during the dissassembly it got loose on me and fell. The little spring and ball came out but I cant tell how its supposed to go back in there? Anyone have any picture of the proper assembly?

I figured it out. The ball is the detent for the cam holes on the switch.

I have 3 or 4 of those peices of junk, took me a year to find one together that worked! more than likely if the air is coming out the defrost vent its the black vacuum line going thru the firewall is not working!
