Oct 31, 2008 (11:08 am)
hello i have a 2003 explorer heat went out after the clicking noise started i have seen the heatertreater kit to fix what seems to be the more common cause of this my question and problem i believe is different the part that has broken on mine is located behind and under the left hand side of the radio, there is a black plastic piece that connects to a metal arm with a hole in it the arm still moves as i adjust form heater to defrost etc the plastic part is what broke and it appears to fit into a hole on the vent assembly however when i put the piece back in the hole to see if i am able to move anything ( like a door or flap) there is nothing in there its very difficult to reach, i have removed the stereo the temp controls and a few other parts to see if i can reach any better it helps. can anyone tell me whats next and can i even buy the part thats broke, is there a flap in there needing replaced ? do i need to remove the dashboard drop the steering ?? if so do i need to disconect the airbag?? is there a diagram of this anywhere ?? i have included a pic of the broken piece that started it all arrows point to the areas that are broke can anyone please help please help !!!??? freezing in the pacific northwest .. and thanks ahead of time 1031081147a.jpg

Your pic link doesn't work for me - you need a place to host the photo so you can link to it. Your CarSpace page would work. Just go to the Photo Albums there and upload the pic from your computer to the album.
There's more in Help (or shoot me an email):
How do I post a photo in the Forums?

The broken piece in the picture is a lever that pushes down on a vacuum control button that controls a vacuum actuated valve on the heater hoses. The lever is positioned so that it depresses the button in full AC mode. The idea is to cut off flow of coolant through the heater core to maximize AC efficiency. The broken piece will leave the heater core hot when the system is in max AC, but has nothing to do with your lack of heat when you are in heater mode.
The first thing I would check is the vacuum actuated valve on the heater hoses. The default for the valve is that with no vacuum, the valve is open and if the lever in the picture is missing, there should be no vacuum and you should have heat. Since the lever seems to be associated with the problem, I'd check the valve on the heater hose to see if it is somehow stuck closed. You can replace the valve with a garden hose splice connector to just take it out of the loop altogether.
The lever to stop coolant flow in max AC is an efficiency invention from Ford. It's a good idea and will make you feel more "green", but it isn't a critical component for operation of the HVAC system. The HeaterTreater replaces this lever and installing a new door would solve the problem with the broken lever, but I'm not sure that it's worth the time and effort to replace the blend door just to get a new lever. The HeaterTreater would certainly be much less expensive than a dealer fix for the problem, but I'm not sure that it's worth the cost to fix it just to improve AC efficiency.
Check the heater hoses going into the firewall. My guess is that your valve is stuck and no heat is being transferred to the heater core. This may just be a 59 cent fix with garden hose parts from Home Depot.

I TOO HAVE A 2003 EXPLORER AND IT STARTED CLICKING WHEN THE AIR WAS TURNED ON.
ONLY THE HEAT WOULD WORK AND NOW NOTHING WORKS.
THE CLICKING NOISE IS STILL THERE.
WHAT DID YOU FINALLY DO ABOUT THE PROBLEM?

well to be honest i am still working on it, i have checked the heat valve as heater treater advised and still no heat, both hoses to the core are hot to the touch so i am on to the next thing, its cold and miserable so i am checking one thing a day by the time i get home its dark and i have no where to work so its a slow process but i will keep u advised but check the blend door actuator first, open the glove drop it all the way down look up on the heater box housing and u should see a small white plastic piece with wires going to it thats the motor or actuator.
