Strange Behavior at Car Wash

[Mill4570]

Pulled my truck into a car wash to spray off dust from a country road trip. This car wash is one with the wand that spays soap or rinse water under pressure but nothing like a pressure washer. After spraying the back and sides of the truck I moved to the front and sprayed the drivers side power folding mirror. The light in the mirror came on as well as all the exterior lights as if you hit the unlock button on the key fob. I quite spraying it and went around towards the passengers side and when I sprayed that mirror, same thing. Light in mirror came on, etc. Before I finished washing the truck, everything went back to normal. A week later, same car wash and same thing with the mirrors. The truck was unlocked and the key fob was in the console. Anyone see anything like this?

Do you have the touch door handles? Maybe there was enough pressure for overspray to hit the handle and simulate you trying to unblock the doors.

It's water running behind the sensor in the door handle. Sensor thinks it's your hand.

Mine did that too. I never noticed it when washing at home; only at the car wash.

My 300S does this. When you spray water on the door handles, the touch sensors sense it

Exactly this!!!
Nothing to worry about.

It's normal. My wife's Edge does it too.

Mine does it washing at home. Doesn’t need to be a pressure washer

I didn’t think about the door handles....Thanks for the help guys

I haven't been to a car wash, but it happened to me at home. I finally realized it was because I had the key fob in my pocket (or in the truck). After I moved the fob out of range, the flashing lights stopped.

Yep, quite normal behavior for these systems. I just leave the FOB inside the truck on top the center console to avoid this.
My Mercedes did this, and so does my wife’s Lexus.

Cheers,

this happens to me every time I wash my truck and if I had to guess how many washes I've given my baby so far I'd say about 30-40. Weird though isn't it?

That explains why mine did it at the car wash but not at home; I never have my keys when washing at home.

Mine does that too. Quite funny/annoying. Looks like a dang Christmas tree going off when I’m spraying it down lol

It’s from the sensors to unlock the doors on the door handle. It sets it off when water hits it

Yes, I have experienced similar weird things when just washing truck using a hose. I think RAM has an issue with these mirrors. I had to have my drivers side replaced 2 wks after I purchased it for being loose. Ever since I started having issues with the backup look down image being blacked out on the drivers side, which indicates a problem with the camera in that mirror. It is intermittent and seems related to temperatures under 40F.
