I have a 03 EB and lately when turning the rear ac on there is a clicking sound all the way in the back coming from the right rear. Sound like a door is stuck and it keeps trying to open (Any1 know how to open that rear panel where the 60/40 buttons are at). When I turn the **** to allow warm/hot air it sometimes goes away any ideas. Also I read the forums about the TSB on the reverse Tilt-down mirrors was wondering if there was a TSB on the 03 rear sensors (backup aid) Thanks in advance!

I had the rear unit replace on my 03 a/c. It's under warranty.
