Mercedes Forum - Mercedes Benz Enthusiast Forums - 2016 E350 AC Blowing Hot Air Intermittently

I'm having a problem with the AC in my 2016 E350. While the AC is running and blowing cold air as expected, it'll randomly blow hot air for a few moments and then start blowing cold air agin. It appears that the problem only occurs on the driver's side. I'll get a quick blast of hot air while the passenger side vents are blowing cold. Since I first experienced this issue 2 years ago, I've taken the car to 3 different dealers on 10+ different occasions to no avail. Each time, I'm told that there's nothing they can do for me since they can't replicate the problem. I escalated the issue to their Atlanta center with no results.

While searching the internet to find a solution, I noticed several owners have posted similar experiences on the Edmunds.com review page. I'm wondering if anyone on this forum has experienced similar issues and more importantly, knows what needs to be done to resolve the issue.

Has anyone experienced a similar issue?
