Windshield wipers stuck on after washing

so I had been chatting about this in a similar 1st gen thread but figured I'd take it here to see if any other 2nd gen owners have experienced this. The last two times I've washed the truck the wipers start going nuts by themselves. This lasts for about 4 - 8 hours after washing. Clearly something is getting wet that shouldn't be. I've taken the truck in to the dealer both times and been told they can't recreate it. Today however, they said they would show their master tech the video tomorrow and should have a fix by Saturday. Anyone else have this prob?

Waiting for outcome....... Crazy

 

Just a normal wash, no engine bay cleaning?

 

Correct. Never popped the hood

Never mind i see you posted on the thread.

 

Yeah thanks, I had posted there and saw a couple fixes from the first gen guys but I wanted to see if any other 2nd gen owners had experienced it.

 

What do you think? @Blueitrgsr

 

Not sure if the OP is the original owner, but some vehicle makes have wipers that turn on when it senses rain.

Could an aftermarket module been installed to simulate a similar function?

 

I used to have a Lexus with rain sensing wipers but not this time. I bought the truck new in October of this year

 

bizzare

as the wiper control is in the stalk on the steering wheel. wtf here?

 

My old Chevy had the wiper relay fail. Sometimes after using the spray function they just wouldn't turn off. Perhaps its a similar issue, water maybe got into the relay/control box under the hood.

Just a thought...

 

I had a relay that was bad on an Acura that wouldn't quit spraying water on the rear window once a spray was initiated. I would first check relays.

 

Update:
I heard back from the dealer today. They said they still want me to bring the truck in Saturday and will give me a loaner car until they have a fix. Pretty good service so far. I'll update when the resolution is in.

 

Just dropped the truck off and picked up my loaner (Camry). They have a specialist coming down from Los Angeles to inspect the truck and plan on keeping it a few days.
