Hi, I have an issue with a Gallardo that the AC works fine and cold on the driver's side and starting from middle vents toward the passenger side vents the air comes out hot. Anyone had this issue before??

i have almost the same problem. all of a sudden i have hot air on all airflow. so i have to stop the car. switche off and restart the monster.
very annoying.

what year is your car?

sounds like the vent flaps are getting the wrong signals. If your cars are still under warranty I'd check in with your respective local Dealers to have the problem resolved.

I have the same exact problem in my 04 "G" also.

I did not have that problem but I have had to replace my A/C condensor and Compressor on my 2004 G

I have been told that this issue was most likely the result of a bad actuator motor. This problem is more common in cars that have had their factory radios replaced or worked on (connection to motor is behind radio). The motor can be eaisly replaced and is relatively inexpensive.

I just replaced my 04 leaking ac line located in the tunnel (3 ft long) so my a/c was low on freon, not to hard to replace and the hose was $180.00. Any issues with A/c I would check for leaks..you can tell by looking for green oil that looks similar to coolant....and running the car low on freon can damage the compressor etc...

where is in the tunnel exactly?

If you have your car on the lift, it is the area where the driveshaft travels to the front differential, the ac line and I think the coolant lines are there also, there is an aluminum cover covering it. I saw the oil leaking out of the edge of the aluminum cover. Remove the cover with the 50 screws and you can see what is going on! I looks just like green glycol coolant so its not hard to miss, hope this helps. next time I have my car on the lift Ill snap a pic..
