[backtolife]

Q:
Would I be able to improve or get rid of the window rattle if the Regulator or Track was replaced on the front drivers side window?

Q:
What is the purpose of the Regulator and Track?

The front passenger side window seems much better & is barely noticeable compared to the front drivers side window.
I would think that both windows should be the same.

if this is correct why is the drivers side rattling?

As the weather gets better I am opening my windows more now.
I have also noticed a slight rattle on occasion when driving on bad roads with the window up.(driver side window)
