Nissan Repair: A/C Replacement and Now the blower is Cracy, vacuum line, gxl

Question
Hi,
I'm just comming back from the shop after the A/c have been repair on my 93 Altima GXL and when I turn on the car and change the gears to "D" the blower start to blow air to the floor area in the car, it is not cool air but it works like if the air is been turn on blowing down to the floor.
The a/c it is working fine after the repair but now it looks like something on the climate control need to be reset after the battery was disconnect while the repair was done.

Thank you

Luis  

Answer
Luis,

They probably messes up a connector to one of the blend doors.  Take it back and describe what it does.  If it were just a vacuum line it would dump to defrost and not the floor.  So, take it back and let them know.  It is on the passenger side and it controls the blend door.
