Re: 2004 Civic Hybrid A/C / Heater fan stopped working
Have you checked fuse #14 under the dash? (assuming it's the same for Hybrid as the "regular" models. Fuse #14 is for the A/C Compressor Fan Relay, Blower Motor Relay, Condenser Fan Relay, Heater Control Panel, Power Mirror Actuators, Radiator Fan Relay, Recirculation Control Motor, Rear Window Defogger Relay.)
What about the blower motor relay? Have you checked, tested, or replaced it? It's in the fuse box under the hood.
Have you tested the blower motor?
Tested or replaced the power transistor under passenger side of the dash?
Tested the HVAC control panel?
