1996 Cadillac Deville V8 Two Wheel Drive Automatic 127000 miles
blower motor don't work, was told to replace motor and computer for heater unit. Did both. Now the computer is used from another cad. Same sn# and model numbers on control box. But no go. Tryed used motor and new motor and neither spins. Tested without remounteing in fan box. Everything on dash works at lease it shows all controls and temps outside and what you want in side. I don't have a clue what gives. Can you give me some help here.
