Windshield sensor?

[SandDiesel]

I am having a new windshield installed in my 2020 1500 Big Horn. There is a small sensor on the back of the mirror pod under the glass. What is it? I'm told I won't need calibration after install.

Is it a rain sensor? Sorry live in Arizona, not much rain this year....

 

[Fatherof3]

I’m not sure what that is , maybe your guess is right about the rain sensor .

I was told on mine its part of the adaptive cruise control if you have it and it does have to be recalibrated. My insurance covered mine at the dealer because the windshield people couldn't do it. they didn't have the software.

I have the same sensor, but no ACC. Do they outfit every truck with the sensor for ACC and it's just a SW upgrade? I would love to get ACC. I also figured it was a rain sensor, but I also live in AZ, so go figure.

That's the automatic rain sensor. No calibration needed, but ensure it's operational after they install it.
If it's an OEM windshield, you should be fine.

So do Big Horns have rain sensing wipers too? I thought that was a Laramie package.

IDK if they all have them as standard, or if it's part of a package. OP obviously has this.

Cool, I'll check my windshield after work and see if mine has it.

This is what i found after doing a search if you don't have the in the systems the chart your good to go. that camera was probably in all windshield of the higher end trucks it does more than just rain sensing.

Thanks, but the pic the OP posted is the windshield IR sensor, not a camera (which is used for lane keeping assisted, emergency braking/crash mitigation, and adaptive cruise. Different systems altogether.

Here’s a picture of mine for future reference (the camera on the far left is just my dash cam).

So what does the IR sensor do? I looked at my Big Horn and I have the same thing.

Rain sensor for auto windshield wiper.

Rain sensor for auto windshield wiper.

I have it and dont have auto wipers

 

[2020GCM]

I believe it is a humidity sensor, used for the auto climate control system. I have this sensor but don't have auto wipers either.

 

[irishwake63]

I wasnt aware I have auto climate control either unless thats standard

 

[Andymax]

I think it's simply a light sensor for automatic headlights, and it could be for both the lights and the auto wipers.

It's the rain sensor. If anything, make sure they get a new gel patch for it, which is cheap. I didn't have an OEM windshield installed after mine cracked, and I have problems with my auto wipers coming on every now and then. Also make sure they're careful with the plastic cowling around the mirror. The gorilla replacing my windshield broke 2 of them before I asked them to just order one and let me put it on.

This ^
Same on my truck as well. Adding rain sensing wipers soon and will have to change out this sensor to the combo sensor. (rain/humidity)

Hope this link helps from a related thread. Yes, this is either a humidity sensor or a combo rain/humidity sensor.

Rain Sensing Wipers (Not equipped but have the part)

I did the upgrade and used JScan. The menu on my 8.4 showed up immediately. Not working yet but going to let it rest over night. JScan - adaptation Radio user setting Rain sensitive wipers on/off Everything work out ok with it? Did you order part 68298334AA and did it come with the gel pack...
