Does anyone know of any reliable brands for these that last longer than a year or two? I’ve had my 2015 FiST since 2018 and have already replaced the DS blend door once and the PS blend door twice. Both times I used Dorman brand, which I thought was an upgrade. But both last winter and this winter, they’ve broken again. It’s a fairly inexpensive fix, but it’s pretty frustrating having to replace them every year.
