I have a 2003 325I with the digital climate control unit. I blew the motor up and had a used one put in by a mechanic now the CCU doesnt display anything.

I checked all the fuses which are good. I think fuse 28 is the main one. I pulled the CCU out and reconnected the connectors. What else could I check? Is there a relay?
