Question about 2002 Ford Explorer
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.

Either a bad blower motor or blower motor resistor. If the air is coming from the defroster only, check for a disconnected or broken vacuum line under the hood by the passenger firewall.

GM uses vaccum to operate the blend doors on their heating and air conditioning systems. There is either a cracked hard plastic line or a cracked, unplugged vaccum line somewhere. If you have done any work to the vehicle latelt I would start by looking there first.
Please remember to rate this solution.

Are you sure the controls you bought is good? Only a few things it can be. Control panel, Blower fan, and fuse. One of those are the problem. Cauld use a jumper wire to send power to the fan and see if fan cmes on. If it does then the fan is indeed good, then go and check and make sure power is on both sides of the fuse. then check the panel. could be bad. Panel sends signal to turn fan on and off. Good luck if need further help let me know, i will try to help ya. I am all about saving money.

There is a diverter valve in the coolant lines. This is used to block the coolant from flowing to the heater core in the summer time. There are 3 types of diverter valves. Vaccum, Eletric and combination. Vaccum is the easiest to check. Usually has a plunger on the diverter and can be manually opened. Use caution when working with hot hoses. Hope this helps.
