Popping Noise From Rear A/C Blower '03 Expo

[Goats]

Mine took a crap today,so it looks like I'm going to do mine tomorrow.

Rear A/C Actuator

It's called a rear A/C actuator that is causing the clicking noise. These go out over time and you should have two of them. Both located in the rear next to the third row seat on the right side. I just got done changing mine out a few weeks ago. Fairly simple to change once you get around the side panel.

I replaced both of mine about six weeks ago. I already have to replace the unit which controls roof/floor. It's Dorman part 604-213. Luckily it has a warranty, so I'll get a new one from Advance, but based on my experience I would not recommend the Dorman brand. YMMV.

I just replaced my acuator not even a month ago and the clicking has returned!!!! I'm sooo pissed! Is there a permanent fix for this issue or am I just stuck spending money on actuators once a month??? To be honest I dont even need the floor vents in the back seats so if there was a make shift way to keep it blowing just from the overhead vents that would be great instead of it being so damn tempermental!

If you just want air to come out of the roof vents, put the control into that position, then when you get air out of the roof vents and the clicking starts, just unplug the actuator..Voila! No more clicking. I did this on mine until I could install a new actuator.

+1. I also just want mine blowing through the roof vents, so I simply rotated the control to that position and removed the actuator. If it was in roof position I could have just as easily unplugged it, but it was on the floor position so I had to remove the three screws holding it in place to back it out enough to rotate the shaft to the correct position, so I removed it.

I replaced both of mine and no prob

Update: this does not work. The damper, with the actuator arm removed, was left free to rotate and moved back to the floor position on its own. I'll need to freeze/glue the actuator arm in position and then reinstall it to hold the damper in place.

If the banging noise is coming from the right rear wheel panel area, it is probably the " Rear Blend Actuator". It sounds like a door trying to constantly open or shut. That happened to my 2003 Expedition in 2011. The part number was ' YH-1767 " YL5Z-19E616-AA
You have to remove some trim. If you have small hands the unit can be unbolted and squeezed out. If not, a lot of the trim must be removed including the upper seatbelt bracket.

After learning that I couldn't simply leave it off, I did this and it worked. The actuator arm doesn't move and I now have it permanently on the roof position.

another victim of ford quality crap click sound in rear today, lucky I was reading the thread a while ago, and just switch the rear ac around and stop when the click stop.

this is my last ford truck suv, im moving back to chevy, they do not have great/best look interior like ford did, but atleast no problem

You can buy a GM and know the government has more tax dollars to bail them out again.
Have fun with the ignition switch!!

all u have to do is replace the 2 little selector motors...maybe $50 for both and i got them from ebay...20 minutes later prob fixed

 

[ExpeditionAndy]

With the new GM vehicles, they use a buss wiring system that runs through the radio so you can't change the radio or the vehicle will not start. Also the way that system is designed, law enforcement or the government can send a signal to shut down your vehicle any time they want. I think I'll stick with the older technology.

can you link me the page

 

[keithnra]

ifinally got this fixed on my 04 simple fix

 

[Jeckler]

I'm done replacing those stupid actuators. I've done the roof/floor one once and the hot/cold one twice. The latter lasted just over a year and last week started making noise again. And this was an OEM part. I'm simply unplugging it in the cold position and the kids can bring blankets if they need to.

Thumping At Max Position Only

Either way the system works fine but once I go the extreme side of the temp control I do hear a thumping noise. All i have to do is back it off slightly and the thumping goes away.

This is annoying and dont like to be limited. What needs to be replaced in order to not have the annoying thumping sound?

Thanks

The plastic gears in the actuator get stripped over time. You can use gears from a gen one actuator from a salvage yard or you can get a new actuator from the auto parts stores like Auto Zone or Rock Auto.
