Having problems with your 2002 Ford Explorer ?
No heat blows from vents. all fuses are good and fan works fine.
First of all, check to see if you have enough water/antifreeze in the radiator. A low water level will create your problem. After that, your thermostat could be sticking. Locate the biggest black hose coming out the top of your radiator and follow it to where it goes into the engine block. The 'housing' that connects the hose to the motor is where the thermostat is located. Remove the 4 nuts around this housing and remove the thermostat. It has a flange in the middle with a coiled spring going through the middle. You can pick a new one up at your local parts store, AutoZone, or Napa for less than $10. 140 degree F type of thermostat will be sufficient.
