I have a 2026 Tahoe and last night when I was driving home the max defog turned on and went to 76 degrees. I turned it off and then 10 seconds later it turned back on. This continued for the entire 20 minute drive home. I hoped it was just a minor malfunction but jumped in this morning and the same issue happened again. Has anyone else experienced this? I wanted to see if there was an easy fix before I took it into the dealership. I've found a few people with a similar issue on other Chevy forums but no answers or resolutions that I have been able to find.
