This noise is the air temperature control blend door actuator motor, it has stripped the little plastic reduction drive gears, this is a common problem on Explorer and the Expedition, in order to change this motor u must remove the dash assembly, the blend door motor is in the approx center of the air distribution plenum between the heater core and the AC evaporator core.

    This was exactly it, BUT, you can do this without removing the whole dash, saving you hours of time. We changed ours out in about 2 hours time. Remove all the front componets, stereo, climate controls, etc and also the instrument cluster. Next remove the steering shaft with wheel. To do this, you will have to remove the 4 studs that will have an inverted torxs type head on them. After you do this, you can move the groups of wires around and with a wobble, a wrachet wrench and a little finesse, you can get it out and the new one in. It will save you a bunch of time with the same end result! Good luck!

I agree with sayerfred. If your A/C is working fine and you only hear this constant clicking noise when the temperatuer knob is moved away from the full cold or blue area, and seems more intense the farther you move the knob to warm or red area, this problem is not the blend door and can be fixed without removing the dashboard. The part needed most often for this specific condition is Ford stock #YH-1744 also known specifically as Ford part number 1L2Z- 19E616-CA. Simply and ambiguously called "Motor", UPC #031508569584, is the correct fix for the problem. I've included all of these reference numbers because the part is NOT available aftermarket (only from Ford) and being a 10 year + old vehicle, most dealers no longer stock this part. You have to convince them that this is what you need and they may have to order it, so as much info as you can give them is critical. You can in fact do this without removing the dash but you will have to remove parts of the center console and you won't necessarily be able to see what you're doing under there so you'll have to feel around with your hands a lot. Once you locate it, there are 4 screws to remove and then pull it out of the control area. It's actually helpful and more intuitive to have the replacement part in hand before starting this job to get a feel for what you're looking for. I paid around $70 USD for the part itself. Although this method is labor intensive, it's far less labor intensive than removing the entire dashboard. Should you decide to go to the extreme and remove the dashboard completely, and you can afford it, your best bet is to replace the blend door assembly (as it is a common failure) and the heater core. The labor costs would be high if you don't do it yourself, but if you go that route, it would be foolish to remove the dashboard just to fix the no heat clicking noise and not do the complete job including the blend door and core as its accessible with the dashboard removed. Hiring a complete dashboard removal/heater core & blend door job could possibly exceed the value of the vehicle itself. Bottom line: If you have the exact problem described (and nothing else wrong such as air not being directed to the proper location) the part number and no dash removal is probably the way to go. I wish you luck and hope you rate this as helpful.

I think the Blend door motor need to be replaced.

You probably have something wrong with either the heater core or the fan. If its blowing cold air on heat then your heater core is out. If you are not getting any air, your fan is out or something in the ducting is clogged.

Good luck

Check the heater control valve, when u switch to heating mode, this valve is supposed to open, allowing hot engine coolant into the heater core under the dash, it is not opening the valve, the clicking is the sound from it attempting to open the valve.

When the temp control is switched to heat there is a clicking noise under the dash and no heat comes of this. The noise is continues until cold air is turned on.

theres a good possibility that the blend door in heater is bad, or the acuator itself. the reason it works when heat is not on is, the heater blend door does not move so you get cool air. when you turn it to heat the blend door moves over to direct heat in car. if its working properly. good-day ! this is for a 2004 explorer, but i believe that it is the same as a 2005. please go to this site for more info, and how to save a few hundred bucks. this site is do it yourself in about 45 minutes. but the garage charges 2.5 hours labor. the dash does not have to come out. good-day!

Heater blowing cold air and fan is making clicking noise when turned on.

check that you have coolant, that is a dangerous symptom, if you have low or no coolant, your heater core will not be able to heat up and transfer heat into vehicle. Clicking is probably just dusty blower motor out of alignment. you will have to remove cover and clean and check alignment

The air control door is probably jammed, and the drive motor is probably slipping and clicking. Dig all the acorns and squirrel droppings out and re-attach the linkage.
