I have to eat a little crow here guys! (When I had previously messed with this issue, it must have been that there was just enough ambient noise that I couldn't hear the motor running thus assuming they weren't!)
Early in this thread I was asked if I can hear them running, I replied "No". Well....a little while ago I went out to the ::QUIET:: garage and manipulated the headrest button and to my 'HORROR' - I could hear the motor running!
This was the case on both headrests.
Sounds like they are off track or the link that moves them up/down is broken/separated. No?
