Got a question about air conditioning & heat, Please Help!

[Mikethomsen]

Hello, I replaced my Blower Motor today but when I hooked it all back up only the defrost vents were blowing no matter what setting I set the air conditioner on. I am wondering if anyone here might know what I did wrong. Any help would be greatly appreciated. Thanks in advance.

The air director (for lack of better name) is moved via vacuum. You may have accidently disconnected or broken the vacuum line to it. When the vacuum is lost, the setting defaults to Defrost.
