If you mean my new seals, they were done both in front and back, plus the vertical strip between the front and rear doors, see the picture on previous page.
Cannot see the pics anymore.
As luck would have it I drove by a Mazda dealership today. No one had heard of noise complaints! However there is a TSB, No. 09-024/18 covering 2014-2016 and some 2017 models. Mazda is only covering under the limited new vehicle warranty which is 3/36k.
"Some vehicles may exhibit wind noise at rear door quarter glass when driven at high speed. This is caused by air leakage from the gap between rear sash molding, rear door glass run channel, rear door glass guide, and rear door quarter glass guide.
Replace the rear door quarter glass guide, rear door glass guide, and the rar door glass run channel at affected side(s) with modified ones on MGSS (REAR DOOR QUARTER GLASS REMOVAL/INSTALLATION)."
GHK1-72-651E is RH rear door quarter glass guide
GHK1-73-6515 is LH
GHK1-72-602B is rear door glass guide
GRT6-72-605A is RH rear door glass run channel
GRT6-73-605A is LH.
I was quoted 193.15 for all part before tax. TSB calls for .05 hours for one door and .08 for two.
