2005 Buick Terraza cxl rear windows dont open?

If the rear Windows of your 2005 Buick Terraza CXL aren't opening, the issue could be due to a faulty window motor, a blown fuse, or a problem with the window switch. First, check the fuse related to the power Windows in the fuse box. If the fuse is intact, test the switches and wiring for any signs of damage. If everything appears functional but the problem persists, the window motor may need to be replaced.
