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!!!

THE A/C IS COOL WHEN AT IDLE, AS YOU REV UP THE ENGINE THE AIR GETS HOTTER, THE LOW AND HIGH SIDE PRESSURES LOOK OK, THE LINES UNDER THE HOOD ARE VERY COLD TO THE TOUCH???

You are correct again. I read your post and the other guy/lady's question and response about the ac. I had the same problem with the ac not working. My wife and i had a argument about taking it in. She just wanted to take it in this afternoon and i wanted to wait and think things out. i wanted to think things out because there are other things we need done to our 2K Explore, brakes, and transmission checked. She had a jerk reaction and i told her i wanted to think about it, the big picture not just the ac. She set up an appointment and I looked on line and you had the solution and saved me some money!! And my credibility!!!! Thanks.

Sounds like a vacuum leak in the control system. A reduction in vacuum when you accelerate is allowing a blend door to open to the hot side of the system, and overcoming the cool side. May be a little hard to find, listen for a hiss, may lead you to it. Could also be the actual control panel leaking air as well. However, I THINK these controls are electric on this car. Could be wrong.

I have an 02' Explorer and the ac works best while driving down the road. Once I stop the air gets just barley cool. any ideas what this could be? Thanks.

I have a 2003 Ford Explorer XLT V6 4WD, the front air blows cold but the rear only blows air. The heat works in the rear, just not the a/c. Does anyone have a clue what could be wrong?

Most likely low refrigerant.

Easy clue. This car has two evaporator units, one for the front, one for the back. The expansion valve for the rear unit is plugged. Not a hard, or expensive fix. If one knows the location of the expansion valve. It's in the line somewhere before the evaporator.

Often when you have two evaporators but only one compressor there is an EPR valve in each line to prevent a single evaporator from "stealing" all of the liquid refrigerant.

#422 of 520 Help! A/C Only Blowing Through Defrosters by teamster445

Jul 30, 2011 (12:32 pm)

Hi - Seems like a popular problem, but I haven't been able to find the solution, hopefully someone here can steer me in the right direction.
 
I have a 2006 Ford Explorer 4x4 Eddie Bauer IV Generation 6cy with rear aux heating and cooling. The A/C is only blowing out the defrosters in the front. Rear AC works fine. Temperature control is working, I have both hot and cold air with no thumping or clicking noise when I turn the control knob. So it doesn't sound like the blend door. I checked the blend door actuator on the lower driver side and its working. I checked the vacuum lines behind the vent control knob and behind the glove box and all connections seem ok. I can reach through the vent and push the door open that blocks the front vents but but it's not opening or staying open on it's own. I also checked the metal arm that attaches to that flap from the vacuum reservoir in the back and it's intact. Seems like maybe a vacuum issue. I'd appreciate any suggestions. Thanks!
