Driver side mirror always fogged up?

[SirenRed16]

Just like the title says, my driver side mirror on my 2016 Silverado with the DL8 mirrors always are fogged up or with condensation on it. The passenger side mirror always clears up within a few minutes of driving. Is there anyway I can fix it without upgrading to Dl3 mirrors? Any help is appreciated.

Clean it and put some rain-x on it?

I clean it once I get in the truck. Driving around in 35ish degree weather within minutes it's fogged up again and the passenger mirror clean.

Anyone else have a clue why the mirror says fogged up?

It might have to do with the wind and the way the dew settles on your truck. The winds are always out of the south here so the right side of my truck is usually clear of dew, but the leeward side of my truck, the left side, is usually covered in dew.

 

What I'd like to figure out is how to turn on the heated mirrors. In my 2011 I had a dedicated heated mirror button, but I can't find it in my 2016. I have an SLT so I'm assuming I have heated mirrors, but how the hell do you turn them on? Do they come on with the rear defroster?

Yes the rear window heat button turns the side mirror heaters on.

It's odd. I have a '15 Silverado and didn't think my truck had heater mirrors. Usually they have the little heated mirror icon on the mirrors to indicate his feature (my '10 Camaro did at least). I was pleasantly surprised that the truck came with this as when I pull underground from driving in the cold my mirrors fog up immediately. Until I pushed my rear window defroster button one day, I would have never even known!

I would agree, more likely related to temps and outside weather. Here in the upper Midwest, temps in the mid-30s usually means dampness and dew.

When you turn on the heat function does the mirror clear and remain clear?

When I turn the heat to clean windshield and back window it cleans but when I turn it off it starts to fog up again.

Yes the rear window heat button turns the side mirror heaters on.

 

Rear window heat turns on mirror heat even it my mirrors don't have heat function?

[Donstar]

Do you have the heat function on your mirrors? If you do, this feature is controlled by the same switch as your rear window heat. You claimed that the mirrors cleared when you rear window heat was on so I assume you have heated mirrors. For the days that they fog up, keep the heat on!

[SirenRed16]

I doubt they have heat thought, my Silverado is 2016 LT regular cab. All my truck has is power adjustable that's all.

As I mentioned above, I didn't think my '15 Silverado had heated mirrors but it 100% does. I was pleasantly surprised. It wasn't listed on the dealer invoice nor is it labeled on the mirrors. But when I turn on my rear defrost you can see it clearing up the foggy mirrors within seconds.
