Rain Sensing Wipers (Not equipped but have the part)

[Rick8325]

Was messing with my rear view mirror to see if I can install my dash cam inside the mirror trim because there’s so much room and it already has a cutout by the windshield and saw this part and looked it up. It says rain sensor. I don’t have it as a setting in my Bighorn radio settings. Why is this here?

I’m feeling since these vehicles are mass produced it’s easier to have the components in and then activate afterwards. Too bad we do not have a Ram tech as a forum member on here to assist us.

I would guess that it also senses outside air temp. Do you have a readout for temp in your truck?

I do but how is that even possible through glass? Lol

 

[HeliPilot]

Not sure, its just a WAG.

it would be nice to get access to an actual Bill of Materials for the truck that lists part numbers that were used.
I know, there are probably over 20,000 individual parts, however one can narrow it down to specific functions/components.
I want to know how many of the "shared" parts that are required for adding adaptive cruise control are actual on my truck so I can just focus on what I need to get.

Just looked up a replacement rain sensor for the 2019 Ram, and that is indeed what you have. I completely missed the fact that you stated it says rain sensor on it. I agree that its weird that its even there. On the bright side, maybe an easy upgrade for you!!!!

where did look this up?

Simple google search for 2019 Ram rain sensor

Here is the part number on it: 68298468AA

I’m sure a simple coding with Witech and new multi function switch and will come alive

And a BAD WAG at that

Thanks your magnanimous

outside air temp is in the driver side mirror

Reviving the thread - my bighorn is the same way.

I'm currently working on enabling the option in the BCM with AlfaOBD and testing functions..suppose to rain tonight.
I was able to get the option to enable to show up in my radio, which I did.
I'm just waiting for physical rain to occur, so I can see if the wipers start working on there own!

Don't feel bad. If you were right, it may have explained why the stupid sensor can't measure the correct outside temperature to save it's life. I understand it's hot outside here in Virginia, but when I get in my truck and 20 minutes later it still shows it being 120 degrees outside, but the weather report says it's in the high 90's, something's not right.........

Now, as for the rain senor working? That's debatable too. I have the setting turned on, and my wipers are in intermittent mode. However, there have now been times where it's started raining and a decent amount of water builds up on the windshield and the wipers don't run. I have to manually turn it to the on position to get it to work. And then, there are times on a sunny day where out of the blue while driving, the damn wipers will make a pass. WTF? So, chalk this up to another feature (like the emergency rear braking) that is much less useful than it was originally intended for.

Spray a hose onto the windshield

Spray a hose onto the windshield

I did, but I think the vehicle has to be in drive, ie. auto wipers won't work in park to neutral...and if I exit the vehicle in drive, the parking break comes on and it switched to park anyway. and I don't have a helper to do the hose at the moment.

My auto wipers work in Neutral and in Park when the engine is running. Had to time it just right to use the window cleaner at the gas station when cleaning across the sensor.
