well if there is no heat, 9 times out of 10 it’s gonna be a heater core(in my experiences). as for the clicking noise i’m not entirely sure, if you could elaborate a bit more, either me or someone else can help ya out ^^
well the clicking noise is just a constant click click click click click click click click doesnt stop
I would be looking at possible issues with your blend doors.
To check the heater core for flow, you can feel the heater core hoses once the vehicle is at operating temperature. Both hoses should be warm. If one is cold, you may have air in the system or a blocked heater core.
I would chase down the clicking first as it sounds like its a solenoid trying to operate possibly. You may also have some debris that fell through the vents causing a blend door to stick.
Here is a video on making sure the cooling system is bled correctly as this can cause a no heat or poor heat condition –

Also, please don’t you caps when posting as to some people, it looks like your shouting and not alot of people will answer posts that are all caps. C8-)
If you just opened the system to replace the thermostat than I would suggest you are air bound and need to burp the system. as for the clicking it sounds
as if you have something stuck in the blower wheel.turn the blower off completely and see if the noise stops.if it does than you will need to locate your
blower and remove the debris. good luck and keep us postedIt is almost certainly the blend door or its actuator. A friend of mine was quoted $600 to fix this because of labor to disassemble the dash. It can be done in about 45 minutes if you throw away the manual though.
It may be a mode door as has been suggested but just to be sure the issue is in the HVAC and related to airflow you might just check to see if the heater core hoses going into the firewall are both warm when the engine is warmed up, if one is warm and the other cool or cold this would indicate a problem with flow through the heater core but if both hoses are warm or hot then the problem is likely to be related to airflow through the HVAC and possibly related to a blend door or mode door not working properly, as stated the ‘click’ noise you hear could be this door trying to operate and it’s not able to but I don’t know that for sure.
Those things are common failures of the blend door breaking and the click noise is the actuator turning inside the broken part. ford will want you to buy an HVAC box to get just the door but a place on ebay sells a door kit for twenty bucks or so.
ok i think i found a easy fix not quite sure though check out this link and tell me what you guys think this is just the tech page that describes my problem well if u go back to the home page you can get reveiws and videos

That’s an interesting article.
You would need to take a look at your own vehicle and see if that is your issue.
Let us know how it goes.
Before buying the heater treater kit, definitely check if your problem is the blend door vs the actuator itself (or any of the other stuff mentioned above). I did this three years ago and don’t remember very well, but I was able to remove the actuator by taking off the knee bolster (below the steering column and the center control panel cover and using a 1/4 flex drive with a small socket to access the hard-to-reach screw. I tested the actuator by keeping it plugged in and putting some pressure on the output while operating it. You can also carefully disassemble it and see the stripped plastic gears inside. You can then manually turn the blend door and see if it operates or not. The actuator itself can be purchased separately from the dealer (I’ve heard there’s and aftermarket part too.)

thanks rick thats my plan of attack imma jump on it tomm my poor wife has been taking it back and fourth to work in this cold but she has tomm off so im hoping just bad gears and not entire flap which alot of post ive found is people bitching about the gears no real fixes lol but thanks for everyones post and yes dreamer i will post updates tomm
ok so here is what was wrong the blend door actuator gear wheel broke teeth off and the clicking was it trying to open for the heat but kept skipping pretty easy to access three little screws hold it in i put an allen wrench into the flap hole and flap still functions so i opened it and wedged a foam piece in there to hold it open until i get the replacement actuator shipped in but easy fix all in all so thanks for all the support
here is the best priced replacment for my 2007 xlt 4.0 manual controls

Thank you for posting the fix! Nice pictures too.
Don’t forget to change the traffic light to green if the issue is solved so it updates our database C8-)
