AC colder on drivers side than passenger side
My AC is blowing cold only through the two drivers side vents. The two passenger side vents are obviously cooler than outside air, but not near as cool as the drivers side. Any ideas? Blend door not fully functioning? I plan to take it in to the local rover shop, but thought I would check here for ideas first.

EDIT: Do you have Dual Climate Control? Do you have both sides set to the same temp?
Here is a page from the RAVE that shows how to manually run the A/C Diagnostics. On my Jaguar, it runs through many more tests, but maybe it will come up with something to help you in this case.

From my understanding, if you've got a stuck door, it should have thrown a code. Maybe it doesn't always???
I'd wonder about something physically blocking air flow (leaves, foam), or maybe a loose connection somewhere (hose disconnect).
Also, maybe the controller itself is not sending the correct voltage to the one side?

You probably just have low refrigerant. Get it checked for leaks and recharged, or at least top it off with a bottle from the auto store.
I had exactly the same symptom. It didn't make sense to me why it would be "sided" instead of just not cold overall, but that's how it was. Driver's side was nice and cold, and passenger was lukewarm. I topped it off and it was cold on both sides. Then I had to replace the leaking hose which was the root cause.

An older thread but I'll try anyway. Have the same problem as Cosmic. 2003 Disco. The drivers side blows cools air.. Not cold but cool enough while the passenger side blows warmer air through the vents and very warm air out of the middle lower leg warmer vent. Ran the manual diagnostics in the morning before work, daylight but not bright sunshine with a 21 and 22 code triggerd. Tried again at three with bright sunlight and no codes but still warm air from the passenger side. Tried again a couple hours before sunset with the codes triggered again. If ther is an open or faulty circuit, would changing the control panel most likely take care of this problem? Thanks.
