I have a 90 pickup with the 3vze and my cruise control works till I hit my turn signal then it kicks my cruise off but the cruise light stays on. I thought maybe with running electric fans it was pulling too much power but I turned them off and tried it and it still does it. And I have leds bulbs and when I hit the turn signals I can watch my volt gauge bounce back and forth. Does anyone does else have this problem?
