I did some initial digging and found the thread for “The Wiper Issue”, which was very informative and helped me possibly isolate the ‘potential’ components that may be causing the problem.
To make a long story short… basically my wiper controls from the steering stalks are not working for my 2012 Model S. The high-beam and turn signals (which reside on the same stalk) work just fine.
A relatively important thing to note is that the Wiper Service Mode works just fine and the wipers are commanded into their ‘service’ position.
I took the car into the service center and they blamed the stalk, and wanted to charge me $600 for a ‘new’ one. I was a little concerned by their diagnosis, and took the car back.
If I understand this correctly, there are only three points of failure for the mechanism that drives the wiper from the stalk (after assuming the wiper motor is fine):
1) Stalk
2)BCM
3)possible wiring issue
If the fuse for [wiper park] was blown, then the wiper would not work at all (service mode would be unresponsive?). I double-check the fuse, and it looked perfectly fine.
Are there any other relays or components that I can check that are directly related to the stalk’s communication/signal to the wiper motor?
When I flip the wiper to any setting it does not respond, and pressing the stalk down to ‘spray’ also does not work.
