Yes: A weak o r low 12V battery can affect the window motors. If the battery voltage s below a certain level, the window motors may not receive enough power to operate smoothly, causing slow movement o r failure.

Testing the 12V Battery: Use a multimeter to check the battery’s voltage. If it’s below 12.4V, consider charging o r replacing the battery.
