I have the same POS 2006 Ford Explorer with exactly the same problem. I have been told to change the radiator, change the thermostat, change the fan clutch assembly, change the blend door. All of which did nothing but help Ford pay for their over priced employee pension fund. I will never buy another Ford product. 2 years old and I cant drive it in the winter unless I want to freeze to death. Pathetic.
 
The roar is probably your fan clutch but who knows. If you have a small leak in your radiator it can also cause the fan to engage and sound like a freakin bus.

I have a 1998 Ford Explorer that mice have gotten into--in the blower, I have taken my glove box out and can see the bower and it had trash in front of the blower and a bit of trash in the blower I got wat was lose out I've had to cut the grid on left side so I can get my hand in there, I'm still cleaning on stuck on gunk, I've yet to get the smell out I turn on the vents and I'm still getting that odor yukkkk--anyway before I started this process the blend door was working fine on max/ac the door closed on regular ac and vent the door opened well the door stopped operating and has started operating again But the door is only open the it's turned on the max/ac it's close on everything else hearter/deforst etc.
now I think I'm crazy WHEN and how does this door operate--seems as if it's working backwards now but maybe I just Thought it was working the reverse before--help--also any ideas how to remove this smell and could it be in the vent if so is there any way to get to them--Ford wants a fortune to do this, I'm trying to do what I can.
Thanks so much for any help

#189 of 520 1998 Ford Explorer AC by dtownmil

My 98 AC does not work at all. Is it worth having the system checked for leaks and charged? I may only have the exploder for one or two more summers and I've suffered through two with no AC already.
 
I tried one of those cans that you charge it yourself and it didn't even make the AC cold for any time period at all.
 
Any advice appreciated. Thanks.

Of course the compressor has to be running properly and providing cooling capacity to the evaporator core inside the plenum box. You should be able to feel one AC line going into the firewall getting icy cold when the compressor is running and the return line warmer. This is a pretty good indication that the system is charged and providing at least marginal cooling. You'll need a set of gauges to check that it is absolutely optimal, but just checking with your hand should get close.
 
A common problem with this particular model is the blend door in the system. This door diverts some or all of the air flow through the heater core. The door tends to break and will let air flow through the heater core, killing AC efficiency even if the evaporator core is cooling properly. The actuator motor for the blend door is on top of the plenum box behind the glove box opening. You can remove this motor and examine the blend door axle. There are two common fail modes and pictures of both are available. The repair involves replacing the blend door and the dealer will want to remove the dash and plenum box to replace the plastic door with another plastic door. Replacing the door is easy, but it's 8-10hrs labor to disassemble the dash, evacuate the AC system and remove the plenum box(figure $800+). There are better alternatives available.

#192 of 520 2005 Explorer vent problem by chsrower

I have a 2005 Explorer the air is only coming out of the defrost and floor. The heat works fine, and the a/c is cold. The only problem is that the a/c won't switch to the front vents. So the a/c just blasts my feet and the windsheild. Any ideas?

#193 of 520 Ford Explorer Heater Fix by heatertreater

On #191, the problem is likely with the blend door or actuator motor. The motor is hard to get to and there are video's in YouTube showing how to get to and examine the motor and blend door axle. The fix is within the capability of most DIY'ers and much better than an expensive dealer repair.
 
On #192, the function between defrost/vent/floor is controlled by the mode door which is a vacuum actuated system. The vacuum motor and door is visible from the passenger side under the dash above the transmission tunnel. If you happen to be a left handed, 93lb, double jointed, contortionist, it's easy to get to...otherwise it's a tight fit. There is a plastic lever from the door that the shaft of the vacuum motor attaches to. This little plastic arm tends to break and will give the exact symptoms that you are seeing.
 
The lever is a plastic piece that inserts into the end of the axle. It can be pried out with a screw driver and you can attempt to glue the pieces back together and get it working again. The HeaterTreater guys can help you with a metal replacement lever if the glue doesn't work out. Once you have it out, you can see the size and axle connector and may find some way to make a little lever that will work or a junkyard piece. I don't think Ford sells this part individually and you would have to buy the entire plenum box to get a replacement.
