The sole task of the Buick Window Regulator is to move the glass section of the window up and down upon demand of the passengers in the vehicle. In its makeup, the window regulator has slides and levels that smoothly move the glass window up and down without binding. It is made out of metal for structural integrity.
When the polymer seal at the edge of the door and the glass window becomes worn, moisture can leak into the interior of the door panel. This is the location of the window regulator. Since it is made out of metal, it will begin to rust. This will cause the window regulator to stiffen when asked to roll up or down the window. In time it will no longer be able to function as it was designed too causing the occupants of the Buick to no longer have access the window without the danger of it breaking.
The procedure for replacing the Buick window regulator is simple and can be accomplished by the owner of the vehicle. With the glass section of the window in the upper most position it should be held there by a block of wood. Then the regulator can be unbolted and removed from the inner door panel. Before the new component is installed, the moving components of it should be lubricated with grease. Once it is back in place the glass has to be reattached on your Buick.
Before the door panel on your Buick door is put back on the window regulator should be tested by moving the window down then up again. This makes it simple to make any adjustments in the tracks so the window will operate smoothly once again.
