Sounds like it could be the infamous blend door problem. Take a look at this website and see if it sounds like what you have.

o.k. when i do this test(below), NONE of the display segments light up. i turn the car on press the a/c buttons and recirc button and turn the drivers side temp control knob clockwise, the two button light light up but nothing else happens. Now if it were the a/c heater control were bad wouldn't i have more problems then just the passenger side heat not working,

  1. To enter the self-diagnostic mode, depress the a/c and recirc buttons at the same time and hold. Rotate the left temperature control knob clockwise (CW) one detent.

There aren't too may WJ on this forum much less ones with the automatic controls, mine is the manual control model.

All I know about the problem is what I've read..
