I have an 07 Mazda 6 / 4 cyl, heat is not working, blows cold air. Other than a stuck-open thermostat, what could this be ?
its very possible for your car to just be low on coolant/antifreeze. check that. if not maybe that thermostat.
my 6 has no heat either. coolant is full and just changed the thermostat AND flushed the lines with water. nothing.
