Ok where to start. Year before last I swapped out my column w/ my parts suburban column. The one in my truck had developed a problem of the wipers going when you put it in park, or if you moved the tilt, the wipers would go until you put the column back in the same place. Fast forward 2 years. Couple days ago, I noticed my lack of backup lights. This column has always been a little funky w/ the backup lights, had to hold the shifter up, like, against P, to make em come on. Well that quit working. So today, I notice I have no intermittent wipers, and to make em park, I have to hold mist till they get to the bottom. If I release too early or too late, they are infront of my eyes Does it sound like these 2 problems are related, and if so, what is it? The wiper motor has been changed for the one off the parts burban (original died), and the wiper delay module (the big finned shiny silver box under the column) was changed when I swapped columns. This one doesnt have the ghetto tilt/wiper problem atleast, but its a pain when its just misting to have to fiddle w/ the stalk to make the wipers do what I want em to. Sorry for the novel, anyone got any ideas of how/why the wipers & reverse lights are related? Thanks. Chris.
