My 2002 windstar only blows heat through the defrost.
Tranny was replaced and van came back this way. Repair shop said it was not anything
they did. Is there a vacuum line that could be off. Any ideas would help!
No matter what position the dial is in the heat still only blows through defrost.

Yup, they forgot to hook up the vacuum line for the climate control system. When the system loses vacuum it defaults to defrost for safety reasons. HTH. -Jim
