2002 Honda Civic, Fan Works only with A/C ON.
Two weeks ago, no heat--we thought we needed a new heater
core. Guys took dashboard off, I guess flushed hoses, unstuck
thermostat, and three days later we got car back and we had
heat again--$700. They said no new heater core needed. Car
has SRS codes on now (so air bags don't work) and after two
weeks, now the fan doesn't work--except with A/C ON. We
have replaced thermostat three times (each time, told it was
probably thermostat). What to do now?
If you have two fans, check the relays for the other fan. Might be a ect sensor. That is engine coolant temp sensor.
Apparently, blown head gasket. :/
