So the dealer recently replaced the bottom heater element in my 2016 GMC Yukon - the heater works now, but I feel the lane-alert haptic feedback vibrations while driving are now diminished I am not sure if this is in my head, but I swear they were more prominent before the heater was replaced (I can barely feel the right side). Could this just be in my head, or is there a real possibility that they somehow didn't replace these motors correctly when putting the seat back together? Thoughts? Thanks!
