So when i first got the car if i pushed the wiper stalk forward it would spray the front windows, if i pulled it back it would spray the rear window. Recently, i have noticed that no matter if i push it forward or pull it back, only the front washer turns on, for both directions. Its strange because they were two separate operations in the past. Anyone else noticed this? Seems to me like its a software issue since its the function of the actual switch that has changed, i'm wondering if its time to invest in a techstream cable to mess around.
