95 vw jetta air conditioning problem..& maybe in need of a new ignition coil

Need to find air conditioning drain hose...my floor board is getting wet on both passenger side and drivers side...if anyone can guide me in the right direction i would appreciate it thanks...(yes i have looked under the hood..and no luck)
 Also my engine has been missing under load I  have already replaced plug wires and spark plugs with original equipment....but I think I may need a new ignition coil but if anyone can think of something else it might be let me know. Thanks for your help!
