There are a series of wires which connect the window switch to the window motor. If one switch works and not the other, the switch could be bad or some wiring connecting them may be faulty.

If it’s sticky from debris or out of place, the regulator motor might not be strong enough to overcome the friction and move the window. The gasket in the window keeps wind and rain out of the car and helps align the window properly. Even if it can do that, the regulator will get worn out a lot faster. Regulators are not always strong enough to force a window away from its frame if they’re frozen together. The reason is that the glass of the windows will stick to their frames. If you live in a region with a lot of snowy and icy conditions, this could compromise the functionality of your power windows.
