Having problems with your 2002 Mazda MPV ?
No heat in my 2002 madza mpv.
\015 I had the dealer flush the system the summer of 2006 or 2007. The radiator was also changed. since then I have had little to no heat in the van. we recently flushed the heating system again and pulled the hoses on the heating core and flushed that also to no avail. I'm at my wit's end. how do I fix this?\015
Two most common causes of your problem are low coolant ( air in the heater core) and a thermo stat stuck open. If you have a temperature gauge and it is reading on the low side. Like 140 Deg or less, you need a new engine thermostat. Feel the top of the radiator tank after the car has been driven. If it is too hot to touch, the thermostat is no the problem. As the system has been flushed and filled I suspect there is enough coolant. Last item on the list is the coolant valve for the heater core. Many cars have a water valve located in line with the supply pipe to the heater core. This valve may be in the engine compartment or under the dash. Check the heater temperature control and follow the cables. One cable most likly goes to this valve. Maybe a cable retaining clop has fallen off
