I bought a 2006 Ridgeline with 300k miles. I notice the rear passenger windows don't go down. Both left and right windows will not go down even with the window buttons on the driver side or each individual button on each window. So I decided to change the window regulator and motor. But even then it still will not work. Now both windows are stuck halfway down and I cant leave my truck like that. So if I changed both window regulators and it still doesn't work, what could be the problem.
