AC blows through defrost only 99-exp 5.4
AC blows through defrost only. I changed the #2 COP and plug 
then re-started and tested and found everything running fine but the A/C. after searching and found that I may have a vacuum leak to the A/C blend door controls possibly near firewall or in the engine compartment. are there any A/C vacuum lines near or around the area of #2 right side of engine?

SOLVED - FIXED | AC only blows through defrost vents
Fixed my A/C only blows through defrost vents issue -
I found that where the AIC tee into 3-hoses - one was dis-connected.
Also the little vacuum line that's behind battery box that travels into firewall also was dis-connected.
And replaced a few 90's medium vacuum line in front of the Throttle Body.
A/C Blows fine like it should through dash vents and also idles better now.
