2000 jeep a/c only blows cold on drivers side

On these 1999-2004 Jeep it was a common problem for the blend doors to get stuck or broken making things not work properly. Mine were fixed under warranty so I didn't have to tear the dash and heater box out. Ugh!

My 2004 did the same thing. There is a vacuum ball under the battery box. You have to take the tray out if I remember right. Replaced the vacuum lines there that were cracked. Worked like new

Or under the intake box. I know its behind the bumper.
