Detailed Product Information

Standard Ignition DFG45 is a window defroster switch designed for vehicles that use a 5-blade terminal layout and female connector interface. In Mazda 626 and Mazda MX-6 models from 1988 through 1992, the listed fitment notes reference rear window defogger module connector compatibility along with rear HVAC floor mode door actuator harness and power seat switch connections.
