AC was working fine but after replacing engine harness now only blows out bottom. I saw that the vacuum hose coming out of the firewall was off so I connected to vacuum but still no movement on the doors. I have the heater control out and don't see anything under the dash unplugged...much appreciated if anyone can help
 
Did you connect the hose to manifold vacuum?
