I have 6 windows that are fogged up. They started failing while still under warranty. Several have been replaced, some of them more than once. I am well out of warranty now and not DRV or Hehr will do anything about it. I feel a recall should have been issued for these windows years ago. I guess DRV and Hehr don't care about customer service anymore. Anybody out there know of a place in South Dakota that can repair them?
