Clicking noise under dash

[grasshopprdisco]

2008 Ford Expedition EL, loud clicking noise coming from under driver side dash at start up only, lasts about 10 seconds.

sounds like your blend door is starting to fail, very common problem with these trucks.

Try to zero in on the source of the noise. It could be anything.

Most likely the blend door like mentioned above. try just moving the blender a tick or two from full and it will probably go away. Mine does it only if I have it cranked completely to the cold side, one tick up and no noise, no noticeable cooling lost either

 

[Denethor]

It could also be one of the other diverters too, if slowly moving the hot/cold blend doesn't make the clicking stop then, try each setting on the diverter (floor, dash, windshield,etc) and see if that causes it or makes it stop. Then you'll know which gear is slipping.

Yeah, wife said that when she switched to defog windshield this morning, kept blowing from dash vents. Clicking comes from behind center of dash, where the console ends and the dash begins at firewall.

 

[Denethor]

So its most likely the diverter door and not the blend door. What year? Climate control or manual?
You might have two issues going on though as I think the clicking noise is the blend door and the not switching from defrost to vent is a vacuum leak or block as that door is vacuum controlled I think, unless they changed from vacuum to electronic in 2008.

2008, manual controls.

I had this same problem recently on my 2010. I took it to the dealership because it was only a couple of days after buying it. They diagnosed it to be the blend door (electric motor with gears. The housing tends to separate over time and causes the gear teeth to misalign and click as they skip across each other). I didn't have to pay it but the total cost of repair was $317 and it took a couple of hours to complete.

According to the technician there are no longer any vacuum switches or controls in the air control system.

The blend door actuator is right behind the radio, one screw is very easily removed, the other takes a super thin socket wrench or possibly a flexable type might bend sharp enough to get to the other but i doubt it. The part is $25 on Amazon (Motorcraft YH1933 Heater Blend Door Actuator). Videos of how to change it can be found on youTube

 

[Denethor]

If it is the Air Door actuator (vent/defrost/floor/etc...) and not the blend door (hot to cool ratio) then my manual says you need part # 19E616

Is The left side actuator the same part number as the right side actuator? (2009 Expedition - Eddie Bauer) Dealer is saying the left side actuator needs to be replaced... at a cost of $1600. The part # they wrote on the invoice is DL3Z-19E616-A.

 

[Denethor]

25 bucks on Amazon, just put that part# in the search. DL3Z-19E616-A is the OEM part #
The replacement part on Amazon is
Motorcraft YH1933 Heater Blend Door Actuator
The dealer is getting you on the labor, because it's hard to get to, so they just remove the whole dash.

Thanks Denethor! I always look on here first, I would never pay that.... I love taking stuff apart, and trying to put it back together!

I love a good ending! Especially when the stealer doesn't get a chance to bend someone over! You know, if they charged a fair price for stuff, they would be able to hire 5 times the number of mechanics they presently have....but Ford and the rest are blind to the big picture and only see the short term gains. They are counting on people being unwilling or unable to accomplish the exact same work as their guys perform and allowing themselves to be *****.

I have a friend of mine who is a Service Mgr at the Annap Mercedes dealer and he tells me it's a running joke at all dealers among the Service Mgrs....to see if they can induce shock on the clients face when they give them the price for the work. They think it's funny to put someone in financial duress. Sounds kind of sick to me but he tries to justify it by saying it's been the culture at dealers forever.

Yet he wonders why I never take my 2 seater to his dealer. I just tell him, "it never breaks".

While we aren't schooled in the exact mechanics of these cars/trucks, we are certainly able to learn with a little instruction help or a quick vid! THAT's why I love this kind of happy ending as much as the other!
