QUESTION: 2002 Toyota Camry XLE

Answer
Remove those pieces, I have no idea what they may be, try to reinitialize the sunroof by doing the following: 1. Push and hold down the “TILT UP”
side of the switch until the moon roof
tilts all the way up and then tilts down
slightly (approx. 10 mm [0.39 in.] at
the rear).
2. Check for proper operation of the
“one–touch slide open/close” and
“one–touch tilt up/down” functions by
pushing the switch briefly to the
“SLIDE OPEN” and “TILT UP” position
