I bought an automatic dual zone climate control to replace the manual dual zone climate control in my 04 d/a cc. Both units have two connectors but only the power connector matches, all the lights turn on. The heater and fan control connector does not match. Does GM use the same wiring harness for SLE and SLT trims??? I ltried to look for the other connector behind the radio and dash but acess was real limited. If not, can an adaptor be used or do I need to rewire to get the automatic unit to work? Thanks for any help on the matter!!!!
