Symptom/Vehicle Issue: Single Pop Noise From Rear Of Sunroof While Opening
Discussion: With aid of a helper, view the roof while operating the sunroof in “Vent”
and “Open” positions. If the sheet metal of the roof is grabbed and pulled down by the
sunroof glass/seal causing a single pop noise follow the below prior to replacing any
components. Note minor movement of the roof skin is normal. The sunroof seal
presses against the roof and some minor deflection will occur without a pop noise.
1. Inspect the sunroof glass seal for damage, taking a “set” or wear to the surface.
The surface of the seal should be slick to the touch. If it is worn smooth, feels
tacky or sticky replace the sunroof glass (seal comes bonded to the glass).
Normal seal appearance is slightly rough texture but slick to the touch. If the
texture is ok and no wear found, apply weather strip lubricant 04773427AB to the
seal. Note it is necessary to remove the glass to apply the lube. Reinstall the
glass and go to step 2.
2. Verify glass installed height first. Refer to service information 23 - Body / Sunroof
/ GLASS, Sunroof / Adjustments. Set the glass position to the 0mm to -2mm in
front and -1mm under flush to roof at rear corners.- Note this differs from service
information. Use non-marring body gap feeler gage Mopar Essential tool
#2022300230 to help center the glass in the roof opening.
