Re: I have a 2003 ford explorer,when the heat is on...
Ask your mechanic, he knows what the clunk is, we dont. Fans dont "clunk" they whine, roar, rythmic clicking, or make vibrations, or dont work. Doors will clunk...usually.

do a compression test to check for head gasket problems
if you have a mechanical fan , replace the viscous fan hub
if it has electric fans , check fans for free movement , fuses(2) fan relay and coolant temperature sensor for operation
Check all your coolant levels are correct and then take her for a good run out....keep your eyes on the temperature gauge,,if your temp gauge hardly moves then your thermostat is at fault....replace it.
If temp gauge works fine, you may be airlocked in your heater matrix... Try setting heater to full heat with fan on full power,, whilst car is ticking over, remove radiator / expansion bottle cap carefully and start squeezing your coolant pipes. This should force any air out through your rad/bottle top..
Please be aware that as your temperature rises in the engine. Your coolant will expand and start to flow out of the rad/expansion bottle..at this stage quickly replace the cap....check your heater...leave engine to cool....unscrew rad/bottle cap, check coolant levels, top up if necessary and squeeze pipes again..start car with heater/fan on full and repeat above.....
no its not too hard if you have some mechanical ability. What you have to do is lower down your gas tank, once it is low enough you undo the lines and wiring that are going into the sending unit. Then you can pull the tank out and remove the sending unit. Your fuel pump is attached to that. Remove and replace it then reverse the removal procedure and you will be on your way again.
Clicking sound is your blend door actuator stripping it's gears and failing to open the door that directs the blower air through the heater core. Follow the sound to the actuator and remove it. Install a new one. You may have to remove some panels to get to it. The part is shown below and costs $32 at autozone. Please let me know if you have questions.
The unit in the back has its own heater core. That's what i thought the clunking was.It has to clunck to go into heating mode.It shuts off the airconditioner The clunk noise just gets louder with age because the strip around the door wears off. The unit in the front has it's heater core is underneath the glove box real hard to get to. In other word's it has two heater cores. That's why i suggested just reversing the hoses and just flushing till you could afford heater core replacement. God Bless Greg
