I need help. My turn signal module p/n 0486190 is starting to act erratic again. It'll work fine for awhile and suddenly stop blinking. When that happens the rear signal lamp stays on even after I removed the key. This will be the third one that's failing. I have this minivan since new. It now have 120 K, Km. The parts guy at the dealer says that it's not a normal failure item and something else could be wrong. However when I replace it each time with a new unit, it works fine until it acts up again. I've searched this newsgroup and Allpar minivan forum but couldn't find any answers.
Thanks.
