I recently replaced the battery and now the A/C only blows hot air. Any ideas? on 2006 Volkswagen Passat

A/C worked fine before. Now its constant hot air when A/C is on.

CK FUSES TO START WITH
Fuse has been checked its good.
poss a/c relay?
Where is this located and is it difficult to work on?
the a/c realy may be part of the a/c control module per all data,or the a/c control module just lost its memory. i suggest you seek help on this as to not cause further issues.when changing a battery in the newer cars you must keeep memory alive using a pwr box as to not cause other issues. sorry but it could be several things. you can try www.alldatdiy.com
