#428 of 520 A/C intermittently blows minimal (warm) air
Aug 13, 2011 (10:01 am)
I have a 2003 Ford Explorer, and the AC after driving for 5 minutes, starts blowing minimal/warm air, and then cools again. Have taken to repair, and they replaced the compressor, but continue to have the same problem. Have taken back to the repair shop many time, but they cannot find the problem. They checked for leak with a blue dye, and indicating it's not leaking. They did fix some seals, but still, the problem persists. Any suggestions, before I continue to spend more $$$ on this SUV without fixing the problem. Ive already been advised that I may wish to seek a 2nd opinion, as they can't find the problem. Any help would be greatly appreciated.

That sounds just like a faulty, or dirty Expansion Valve in the line. It should have been replaced with the new Compressor, however, lots of shops don't bother to do that. So: If they did replace it when they changed the compressor, it's likely bad. IF they didn't replace it, it's likely plugged with debris from the lines. Either way, I'd have it replaced. It's very cheap part, and half an hour to replace. Not a big deal.

#431 of 520 2002 Explorer Blower Only Through Vents
Aug 19, 2011 (1:14 am)
I have a 2002 Explorer. The A/C and Heat control works fine. Cold air when I want cold and hot air when I want hot. But the air will only blow through the cabin vents. If I turn the controls to floor or defrost, the air stills flows through the cabin vents. The controls do not change the direction of the air flow. I recently replaced the motor blower resistor and the blower speed control now works as it should. Can anyone give me some insight on what the problem may be. Thanks

Hi stimm I have a 2004 Ford Explorer but yours could be the same. Open your glove box ans gently push the back sides in to each other and then your glove box will drop down some more.Then look with a flash light right in the left top corner behind the glove box. You will see a vacumm rod that is suppose to slide into your vent changer, that could be broken. What I did was pull gently on the rod and try my vent dial , when i could get my rod to give me all vent air. I then pulled off the vent dial in that posistion and put a piece of plastic that I made round to fit so that I would not turn that dial for defrost, floor or center vent. I am getting air condition this way and also all vents are on. I know this is a major problem with Ford Explorers but i read that Ford is not fixing it. willjk
#433 of 520 2002 Explorer HVAC Flow Control Valve and Door
Aug 20, 2011 (4:30 am)
2002 Ford Explorer.
Symptoms: AC and heat controls work fine. Fan speeds work fine. But air flows only through front vents. When I attempt to change air flow to floor or defrost, the air continues to flow through the front vents.
Observations: There is a flow control valve located to the upper left of the glove compartment box. When I turn the flow control switch on the front panel from floor to vent to defrost, the valve rod moves in and out as it should. The valve rod though is to be connected to a plastic lever arm that pivots a flow control door or flapper. This plastic lever arm has broken and is not connected to the valve rod. Can anyone tell me how I could replace this plastic door and reconnect it to the valve rod.? Thanks

Hi Stimm You would have to remove the console and part of the dash to get to the plastic control. Look up Youtube on how to remove dash on your year. I left mine alone because of the cost, I was able to pull on the control valve and keep trying your flow control switch. I was able to get air from all vents at once. So I pulled off the flow control switch and cut a piece of black plastic and placed sticky tape inside and placed round piece of the black plastic disc that I made to cover that opening so that I would not use the vent control and my vents are fine, as long as I don't touch that flow control switch again. I also get air condition through all the vents also.
#435 of 520 A/C rear line replacments 2008 EB Explorer 2008
Aug 29, 2011 (5:25 am)
I have a 2008 Eddie Bauer with 3 rows of seats, 4.0 liter engine with 43,000 miles and my A/C is blowing hot air. I brought it to a dealer who told me the that the "lines to the rea rA/C unit need to be replaced" The cost is out through the roof. 1) Is this a common problem with the ED "rear A/C unit and 2) can I simply seal off/plug off the rear A/C unit as no one ever sits in the 3rd row of seats.

That's ridiculous! There surely is a leak, but very very doubtful it's the lines to the rear evaporator unit. Go somewhere else and get another diagnosis. I think you're getting taken for a ride. Those lines should last 20 years.
