Hello fellow Mazdas,
I have a 2009 Mazda 5, the heater just stopped working suddenly the other night. I smelled coolant and it started to overheat, so I pulled over and noticed some water near the rad on the drivers side.
It was late night so the next morning I checked it out, couldn't find any leaks. Filled the reservoir, ran it for about an hour and nothing leaked....i thought for sure a busted hose or even the heater core.
I then disconnected the hoses from the core at the firewall, and flushed the core in and out, nothing seemed clogged, all flowed fine. I then took apart the glove box and half the dash to look at the solenoids in the plenum. All are working, mainly the hot/cold. i can see it moving up and down when setting the temp. I can even hear the airflow change as the valve/solenoid moves.
I just cannot get any heat at all. Blower works well, all the vents work as they should. It seems like the hoses to/from the heater core are not flowing (they were nearly empty when I removed them), but I don't know where to go from here on this car. It's not overheating and it's not leaking coolant. I don't know where that water came from before, it was on the drivers side by the radiator, opposite the reservoir. But I can't get it to leak anymore.
Any ideas, anyone?
thanks,
Dave
