Default Passenger window won’t roll up

So recently I replaced the window regulator.

The window now rolls down and rolls back up, but on occasions it rolls down, and I try to pull it all the way up, it just moves down. I would have to roll the window all the way down and back up. Strange huh?

I started tugging on the window and I found that it’s misaligned, and it doesn’t stay intact when it rolls up or down. So when it doesn’t like being rolled up, I push the window glass down then I push the switch for the window to go up.

What can I do to remedy this problem?? Do I need a new motor?

Check that the cradle that holds the glass moves straight up and done. Then make sure your glass is positioned right (not misaligned).

Once that crooked-ness is fixed, you have to teach the system the right force to apply ... by holding the switch up-while-the-glass-moves-up-all-the-way and down too.

simplecar,

Another reason the window does not respond correctly to the power button is a bad relay on the window switch controller board. Were you having that issue before you changed the regulator?

I did have that issue. I replaced that bad relay and it worked fine, it responds, it’s just the issue where it would like to go down but then I have to realign the window glass for it to go back up.
