Is it possible to retrofit an 09 G37X couple with the rain sensing wiper system?

 

Anything is possible with enough money. However, in this case I don't think it's practical. You'll need the rain sensing module, new wiper control stalk, and possibly a new BCM. You may also require a new wiring harness depending on what the connections are like for the rain sensor. Not to mention all the labor involved.

 

how do you know whether you have rain sensing wipers or not? does it come with tech pkge?

 

yes, it's in the tech package

 

You'll have a big black plastic square next to your rear view mirror. Also, your wiper control stalk will have an "auto" setting like the headlight control stalk.

 

i have tech package but my wipers never turn on my itself... do i need to find auto and leave it in that setting to work?
