OMG! I got it!!! I have been driving this car for almost a year and just now found how to make the washer work! I read the manual, and could not understand how they explained it... You push the entire STALK forward on the right side, just like the high beams on the left! I got to tell you , that I have been driving for 40 years, have owned over a dozen cars, and never saw this... It has always been that you TURN the rear wiper switch a little extra, or PUSH the end of the stalk inwards towards the steering column
, but NEVER PUSH the stalk AWAY from you ... Thank you so much!!
