Enter your question.I have a 2004 ford expedition. The front a/c blows cold but the rear blows hot. Thought it was a vent motor but when I moved the vent the air blew hotter. What controlls rear temp. Is there a seperate charge point for the rear? If so I cant find it.
It all runs from the one compressor under the hood, but has a seperate system to an extent. It sounds like you have a problem with the blend door for the rear AC. If you are getting heat, it sounds like it is stuck.
