What the heck is this?

Anyone know what this thing is, bottom/front of the driver side mirror?

 

[NJMOPAR]

Temperature sensor

 

[Nicholas Cove]

Yup thats the ambient temp sensor.

 

[BadHemi2014]

Ok I'm so glad you asked that because I never knew what that was lol.
Thanks guys for your collective wisdom!

i thought this was like a little puddle light that illuminates when you un lock the truck?

I broke that thing just a couple of days after getting my truck because I just can't leave stuff alone.
I thought it was a button to open the little square thing around it.

At first i thought that it might be a Proximity Sensor, but the other mirror would have the same thing on it

I never liked the ambient temperature sensor in the driver's side mirror, it is always incorrect, because it is surrounded by hot plastic, reflective glass from the side window & a metal door

The engineers must not have studied how temperature gauges work

When you mount an outside temp gauge on a tree, you are supposed to mount it above the tree trunk at the line of where the leaves begin & the breeze can pass over it.

Before they mounted them in the mirror, they mounted them behind the grille & off to the drivers side of the radiator & condenser fins & the temp gauge reading was real close to correct

Just wait until you do a quick car wash and it’s 93 outside and the gauge says 68. It’s going to blow your mind. Then the water clears and it goes back to normal.

Thanks for the info, I thought maybe it was an antenna for the remote start or something lol.

 

[GTyankee]

The remote start antenna is behind the back seat on the drivers side near the vent

It is called a RF Module

 

[Andy Morrison]

Don’t be fooled. It is a camera so the government can see your every move. Lol

Very true. I was always amazed at how accurate it was and the reading never seemed to be affected by baking in the sun. The new mirror mount-not so amazed.

Is this the same RF antenna/module that provides the signal for the proximity sensor to unlock the door when you grab it and to lock when you push the button on the handle?

 

[GTyankee]

From what i understand, the RF Module is what allows the FOB or RKE to function

Fun Facts:

FOB is short for FOBIK = Frequency Operated Button Ignition Key

RKE = Remote Keyless Entry

 

[Scrounger]

Its a light for when your backing a trailer, button is at bottom of light knob below fog light button
