My climate control is not working properly. Driver side does not blow hot air (as hot as the right side) and the right side does not blow cold air (as cold as the driver side). This is happening when both side are at the same temperature in the A/C climate control.
What's going on?

 

Could be either the duct sensors failed or the A/C computer control unit taken a powder. They are generally pretty robust apart from the lamps in them. My 'guess' is it's the duct sensor(s) playing up. If you can get your hands on a good code scanner (Hawkeye or Nanocom or similar) it should throw up a code showing what has failed in the A/C system.

 

I had a similar issue, fixed it by cleaning the little temp sensor to the left of the steering wheel. It was completely full of dust and dirt.
