My blows cold and I hear a clicking sound from the inside...what could it be?

There are electric motors that move blend doors in your dash board. The blend doors control the heat/cool ratios as well as the location the air will blow from. It's very common for the doors to break or the motor to fail and require replacement which can be costly.

2002 ford explorer AC and heat blowing in dash, but very weak from the vents

On the motorcraft parts web site, you can blow up
a picture of the HVAC Blend Door Motors & locations,
as well as part numbers

You can get failed motor from Amazon

With knowing where the motors are located, try switching
the air flow modes manually, to see what positions do not work

Then you know what motors to replace

I also have professional scan tool software & can see the codes
for the motors in enhanced data.

No heat

i just worked on a 2004 explorer. it had no heat and the ticking sound of the blend door motor. replaced motor. took care of the clicking sound. but still no heat. tinkering around for a few hours reading forums and doing some test. i never gave it the thought to KEEP IT SIMPLE STUPID! it was low on antifreeze. i added some earlier but after running it and bleeding the lines and topping off the water it blows hot again.

it is called a blend door acuator problem. it is what moves the door from hot to cold or vice versa. it is usually way up under the dash and is very hard to get to.usually requires dash disassemly. do yourself a favor and take it to a mechanic. it will save you $$$ in the long run.

The clicking is the air temperature blend door motor, most likely the motor will have to be replaced the blend door checked to make sure it moves freely, this repair requires the removal of the dash assembly.

2003 Ford Explorer is knocking and blowing cold air when I turn the knob to the heat

The blend door (mode door ) is a very common issue there is even an associated TSB t(technical service bulletin) it has to do with the blend door becoming warped and binding the accuator. In an opened or semi-closed position

02 heat,makes thumping noise when temp turned to heat

  The concern lies in the temperature blend door. Most likely if it is clicking the door is broken where the motor shaft (the motor that actuates the door) goes into the door. Replace both the door and motor ( unfortunately from Ford the whole heater box needs to be replaced) or an aftermarket such as Dorman may have the door separate.  The entire dash needs to be removed for the repair so it is quite costly.
