#405 of 520 Air Conditioner Output rotates automatically
Jun 21, 2011 (4:01 pm)
I have a 2002 Ford Explorer Eddie Bauer. Recently I noticed that the air conditioner will automatically rotate the output of airflow from the dash to the floor to the windshield every 30 seconds or so. It doesn't matter if the A/C is on automatic or on manual and I am attempting to tell the A/C to blow out of the dash, the floor, etc. What could possibly be malfunctioning and what $$$ am I looking at for repair?

I have a 2005 Ford Explorer, XLT 4wd. About a month ago my A/C pumped out cold. Now its jut blowing air with hardly any pressure. Although I can hear the fan at full blast the emitting air has low pressure, and the air is ambuient. Could you please give me a possible whats going on.

Depending upon whether the blend door that controls the direction of the output is electric on that model, or vacuum driven, you either have a bad switch, or a vacuum leak that is letting the door cycle. Neither are a really simple thing to deal with, unless you get lucky and find either the switch on the dash, or a hose leaking under the dash that is easy to find and get to. Otherwise, you may need help.

Did you get this resolved? I may have a similar problem with my 2005 Mercury Mountaineer. Air is loud when fan speed is turned up to 4 (max), but it doesn't seem to blow out as strong as one would expect.

70K miles on the mountaineer. I did not notice a filter in there.

There is no filter on these cars. What usually happens to these, because of the ABSENCE of a filter, the evaporator coil clogs up with dust and grime from the airflow, although not usually until a bit later in life. Some cars, you can get a hose in there and clean it out. I dont' know if that's possible on these or not, I never tried. My 03 did the same thing, but it had 140,000 miles on it when I sold it, still running strong, by the way. It's also possible to have a blend door not functioning properly, or an obstruction in the intake.

CLUSTERBUSTER IS RIGHT!!!!! Pop the glove box down and look at the vacuum cylinder (brass or aluminum) in the upper left part of the void left by the box. There should be a lever attached to the plunger of cylinder, THAT IS THE FLOW CONTROL VANE OPERATING LEVER. Moving the lever changes the flow location. The CRAPPY TIN METAL LEVER ARM on the flow control vane broke and wasn't attached to the cylinder, SO I ZIP TIED IT THE CYLINDER PLUNGER (it has an eye at the end) AND VANE LEVER TOGETHER, ran some tests, adjusted the zip ties some, and VIOLA!!!! $200 MY ASS SUMMERVILLE FORD!!!
