Use to get a chime when selecting either Memory #1 or #2 when the seat and mirrors were in place....or when resetting Memory #1 or #2.....no longer get these. Still hear the chime for when the top is in the down or up position; hear the back-up sensor, the auto alarm set.....those chimes all work.
Is this a failure of one of the seat modules?

 

First thing to check is the speaker in the steering column. John Dee has a good Youtube video on the subject.

 

The steering column speaker is fine, have turn signals clicking and gear selector sounds as described in the video.

Next??
