Well...I never ran the previous code check...however, we're back at it...almost exactly 1 YR LATER....last time we had this problem, the dealer has us listed as coming in with it JUN 1, 2012...now, in JULY of 2013, the same issue has returned...I'll get it re-charged again, however, I would like the dye added to test for a leak...I had this symptom on my 2005 EX-L...problem is caused by low refrigerant. I hate to ruin all the rocket science going on here, and I'm not saying that it COUDLN'T be something complicated, just that it's probably a lot simpler than what's going on here in the mad scientist club.
Basically, find the leak. Mine was on the high side pipe connecting the rear unit to the front compressor. I put dye in the system, and thought it was antifreeze when I first saw it on my driveway....what a dummy, huh? But anyway, once I realized it was dye, it was easy to find the leak. The pipe had simply corroded due to the corrugated plastic covering the turn up into the cabin, which, instead of protecting it actually trapped water and road salts against the pipe, and ultimately corroded a hole in it.
Find the leak, hopefully it won't be too hard to fix, and you'll be good to go.
My wife ran into this problem on the way home from work. HOT air from the driver side and cold air from the passenger side. I knew immediately that it wasn't mechanical but rather electrical since it happened so quickly. I searched google and came across this thread. For me, the blender motor was stuck in the open position.
I moved the drivers side seat all the way back and pressed in the parking brake for clearance. I laid on my back on the floor board and searched for the dark grey box with a green plug and white arms near the center console. Once I found it, I turned on the van and set the AC to LO. All I did was lightly touch the arm on the blender motor and it popped to life. The drivers side vents went from HOT to cold instantly. If it happens again, I will continue to fiddle with the box until it finally dies.

Silicone or Teflon Spray will be fine.Had the exact same problem some up tonight when my wife was driving home. 2007 EX-L. In my case it was also the control arm was stuck in the closed position (grey box, green plug, white arm, by center console). I played with the arm while AC on. then I turned the AC temp all the way down, to the lowest setting, then it slid out of the stuck position and started working normally with cold air in both sides when I returned the temp to 65. So for me it was that arm got stuck on one position. ANybody know what type of lubricant I could put on that [plastic arm assembly? Thanks, everyone! This forum is awesome.
CNN, Thanks for pointing me in the right direction. I followed the lead of "belundy" in post 18 of that thread. He repaired the part by opening it and cleaning it. That worked for me. See the photos below.First...your dealer is a hack, so stay away from them.
- If you have COLD air on pass side, this means your AC system is working fine.
- When you have a differential (hot one side, cold the other side), then one of the "blend door motors" is defective.

The values above make more sense in context of this chart:5. Driver's Air mix opening (% of opening - Lower value indicated cold air distribution, higher value indicates warmer air)
7. Driver's vent temp (°C) :huh:
