#7 of 232 2001 Ford Expedition Rear Air Conditioner Problems
Feb 21, 2006 (7:25 pm)
Need assistance, looking for the electrical diagram for a 2001 Expedition, XLT Sport Edition. Took the truck 3 months ago to get the oil changed, all of the sudden the rear a/c stopped blowing cold air. A week ago I did my own oil change and noticed a loose connector underneath and I am asking myself if this has to do something with the A/C situation. This connector is nearby the drain plug. Looking for the diagram in order to troubleshoot it.
#8 of 232 2002 Ford Explorer Rear Air Conditioner Problem
May 07, 2006 (4:49 am)
I have a noise with my rear air in my 02 Explorer. It sounds like a pump or something pulsating. Its a constant click, click, click. The engine does not have to be on, just the ignition. The rear air still blows cold. I pulled the panel off in the rear and it feels like its coming from a clear colored part behind the air unit. I unplugged the rear air to get rid of the annoying noise. When it started it would continue for about 30 minutes and then go away. Now it does not go away.
If anyone has any idea's on what this might be, I'd love to hear them.

I have just stumbled upon your problem while trying to search for the part to repair my exact same problem. My noise presented itself in almost the same way, however, occasionally the kids in the back would complain that the A/C was blowing hot air. The culprit in my 2003 explorer seems to be the air temperature mixer control for the rear air. There are two controllers on the rear air unit...one to control the air direction (up or down) and the other to control the air temp. They are both constructed of white/clear opaque plastic. The air temp. controller went bad on mine...it appears to have stripped a gear inside the sealed unit. I checked it by removing the unit from the main blower housing and plugging it back in. It did not click until I grabbed the shaft that goes into the mixer door on the housing. It felt as if it had stripped out and would not move when I was holding it with my fingers and just click. I guess the only way to repair is to replace the controller (don't know the cost yet, but it appears it is a dealer part and is probably expensive! ) I guess you have had the cover off to at least see these from your description of your problem. You have to remove two bolts and one nut to loosen the housing from the Explorer body enough to pull it out far enough to remove the controller(s)-- (3 screws hold them on) . You could just unplug the elec. connector to this controller to stop the noise as a temp. fix. Hope this helps!!!">

Just fixed my 2002 Explorer with this issue.
You'll need part number #YL5Z-19E616-AA costs $86.06 + tax.
It is the unit described by jminier in his reply.
The box snaps apart by 2 plastic molded clips on each of the 4 sides.
The gears had teeth that were indeed broken. I did some more investigation as to why this happened. The box is a simple DC motor / gear assembly with a wiper resistance pot to feed back position. The cars controller does not have the correct set points for the stopping points. This problem drives the motor even when the mechanical stop (flap is fully open or closed) is reached. This continued pressure strips the gears and causes the clacking noise.
We all need for FORD to better engineer their vehicles so this does not happen.
I have not dug into the controller to see if the end points can be adjusted to turn off the motor at the end points.
Let us all know if someone does this work.
Hope this helps (it is not cheep)

I have this same problem. Can you explain how to get the cover off? I'm assuming you have to remove the interier panel?

I have a 98 Expedition and had a problem with the rear only shooting out cold air, not hot. After tearing out the rear interior trim and was able to access the blower and heater core assembly, I found the blend door (which is what allows the hot/cold air through) was broke. This is a very common problem with explorers and expiditions. Very easy part to change for the rear. You just have to remove alot of trim to access the housing for everything. Also, the rear heater core was clogged and I had to replace that myself. I reccomend troubleshooting and fixing yourself. They will charge you an arm and a leg to take it somewhere.
The front on the other hand is a pain in the you know what. I replaced the heater core in that. You literally have to take out the whole center console along with the whole dash board and everything in tact. After replacing and getting everything back together, I still had no heat. That is when I heard the "blend doors" go bad 95% of the time you have ac/heat problems. So for a temp fix, I drilled a small hole behind the glove box, into the left side of the housing for the heater core, and used a screw driver to pry open the blend door till warmer wheather comes and I can rip the dash out again to repair. Good Luck!
The front is a whole different story
#16 of 232 Strange noise coming from rear heater in 2003 Expedition
Mar 15, 2007 (3:01 pm)
A noise started coming from the rear heater in my 2003 Expedition this winter. At first I thought it was one of the kids kicking something in rhythm but then found it to be coming out of the rear heater. Does anyone know how to open that rear panel or has anyone heard of this noise?
