i replaced my heater core last night and did a drive let the engine heat up so i turned on the heater and gave it sum time so it could heat up. the heater still doesn't work
So I'm having a similar problem with my heater. I just replaced the blower motor and the control switch and now it works, or atleast you can hear it working. There is no air whatsoever coming out of the vents or defrost. Any Suggestions?
