I have a 2006 Kia Sportage and am having troubles with the rear hatch window. Initially it seemed that the metal prongs on the rear window that “plug in” to the control box when the window is closed would get gunk on them causing the window wiper, defroster, and upper brake light to not work (or only work intermittently). After cleaning with alcohol wipes, the problem would be fixed for a week or so. However, now, no matter the cleaning, the issue will not fix itself.
Oddly, if I turn on the rear wiper blade and go around to the back window and press the window in where the “plug” is located, I can make the wiper work. This leads me to believe that a problem with the “plug” or the gas pistons that hold the window open/closed. After speaking with a mechanic, and demonstrating the problem, I asked if the pistons could be worked on or if the plug (male or female end) could be replaced. The response was an “I don’t know because I’ve never dealt this this sort of problem on a Kia.”
Can anyone offer any advice on how to fix this? Houston can be quite rainy at times and I would love the use of my rear wiper blade and brake light.
