#200 of 537 2004 Explorer a/c concern - blows cold passenger side & warm on driver side
Jun 23, 2009 (4:06 pm)
Please help -- I have a problem with the manual air conditioning system in my 2004 Ford Explorer.
The vents on the driver-side of the vehicle (includes left vent on dash center panel, vent on left-side of steering wheel and left floor console vent) blow warm air whenever the A/C is in the maximum (re-circulated interior air) and regular (draws in exterior air) positions. This warm air condition is most observable when outside air is used. I believe this is because as the a/c system re-circulates the interior air in the "Max" a/c position, the difference in vent temperature diminishes.
1. Air flow volume appears normal
2. Right-side (passenger side) vent temperature is in the 65 to 68 degree range (not precise as inexpensive stick-on thermometer was used)
3. Left-side (driver side) vent temperature appears to equal the temperature outside of vehicle when a/c is in regular position
4. Left-side vent temperature slowly equals right-side as the interior cools (only applicable when "Max" position is selected)
1. What should be my next steps to attempt to diagnose the concern?
2. Is there a physical divider in the a/c system that splits the cool air distribution into two distinct (driver-side & passenger-side) sections?
#202 of 537 04 Ford Explorer, front vents not working
Jun 29, 2009 (11:57 am)
The front vents on my 04 Ford Explorer have stopped blowing air. The floor, rear, and dash vents are all working fine. This is the case for both heat and air. Can anyone tell me what the problem could be, and if it would be easy for us to fix ourselves, or if we should just take it to a shop. Also if anyone knows aprox. how much it would cost to fix this problem. Thank you so much!

I am having similar problems with my 04 Ford Explorer. Were you able to get this problem fixed? If so, what was the problem, how did you fix it, cost, etc. Thanks! My rear vents are blowing fine as well, not sure if yours were working or not.

This is strange behavior and you'll need to check several things to get to the bottom of the problem.
1. Is the air flow strong and changes with fan speed on the defrost/floor/dash vents? Need to make sure that there isn't some sort of blockage of air flow into the fan motor. If flow isn't changing with fan speed, suspect the re-circ door.
2. Did this occur all of a sudden or was some work done to the dash panel before the symptoms. It's easy to get the dash panel out of alignment when you attach it to the frame and a misalignment may diminish flow through the center vent. You can always pull the center dash control panel and make sure that the vent is clear.
3. There is a spring loaded valve on the center vents that opens when the vehicle is on max heat. If the vent doors stick, it will block air flow during normal operation. Does the vent come to life when you go to max heat? If the flow changes then the problem is this sticking vent. The vent is opened when the blend door moves to the full up position and is meant to give a little boost of heat when the heater is first started. It's kind of a dumb idea since the air is cold at first and rapidly becomes too hot and you have to turn the heat down. If this is the problem I'd suggest just removing the front control panel and breaking valve. It's only purpose is to make the passenger compartment warm up about 30sec faster. We can provide pictures if you search the user name.
4. The center vent door is actuated by the blend door moving up and down. If the door starts to get out of alignment, it can push the spring actuated center vent door to the side causing it to jam. This is an early indication that the blend door may be going bad. When this breaks, you lose control over the temperature control in the system. We have extensive information on the doors and a technical explanation of the operation and design flaws in the system. If the door turns out to be the problem there are aftermarket solutions available.
I would be interested in knowing what you find.

WHERE DO YOU FIND THE RESPONSES TO THESE QUESTIONS? SOME MENTION PHOTOS, DETAILS ETC...
HAVING SAME PROBLEM AS MANY OF THESE POSTS, AND WOULD LIKE MORE INFO ON HOW TO ACESS THE BLEND DOOR VIA THE GLOVE BOX.

I have exactly the same vehicle (2004 Explorer) and exactly the same problem. If anyone can advise how to check or repair the blend door without dismantling the dash, please chime in. Thanks.
#208 of 537 '93 Explorer Blower Intermitant

Blower only works intermittently. I've replaced resistor package with no success. Next applied a 12volt line directly to blower and it turned on. I'm thinking dash switch? Any other place I may look?

heatertreater, my AC seems to work in that it will put out cool air, but the Max AC portion does not seem to be working. The air output does not increase and the air does not get cooler over time when Max AC is selected. Do you think your blend door fix will take care of my problem?
